libc: Reintroduce getentropy.

This was introduced two years ago when the getrandom/getentropy API
question was still open, and removed because the discussion was
ongoing. Now getentropy is more widely adopted and soon to be in
POSIX. So reintroduce the symbol into libc since we'll be keeping it
anyway. Discussion of details of the semantics, as interpreted by
NetBSD, is ongoing, but the symbol needs to get in before the
netbsd-10 branch. The draft POSIX text is
(https://www.opengroup.org/austin/docs/austin_1110.pdf):

SYNOPSIS
#include <unistd.h>

int getentropy(void *buffer, size_t length);

DESCRIPTION
The getentropy() function shall write length bytes of data
starting at the location pointed to by buffer. The output
shall be unpredictable high quality random data, generated by
a cryptographically secure pseudo-random number
generator. The maximum permitted value for the length
argument is given by the {GETENTROPY_MAX} symbolic constant
defined in <limits.h>.

RETURN VALUES
Upon successful completion, getentropy() shall return 0;
otherwise, -1 shall be retunred and errno set to indicate the
error.

ERRORS
The getentropy() function shall fail if:

[EINVAL] The value of length is greater than
{GETENTROPY_MAX}.

The getentropy() function may fail if:

[ENOSYS] The system does not provide the necessary
source of entropy.

RATIONALE
The getentropy() function is not a cancellation point.

Minor changes from the previous introduction of getentropy into libc:

- Return EINVAL, not EIO, on buflen > 256.
- Define GETENTROPY_MAX in limits.h.

The declaration of getentropy in unistd.h and definition of
GETENTROPY_MAX in limits.h are currently conditional on
_NETBSD_SOURCE. When the next revision of POSIX is finalized, we can
expose them also under _POSIX_C_SOURCE > 20yymmL as usual -- and this
can be done as a pullup without breaking existing compiled programs.

GETENTROPY(3) Library Functions Manual GETENTROPY(3)

NAME
getentropy - fill a buffer with high quality random data

LIBRARY
Standard C Library (libc, -lc)

SYNOPSIS
#include <unistd.h>

int
getentropy(void *buf, size_t buflen);

DESCRIPTION
The getentropy() function fills a buffer with high quality random data,
suitable for seeding cryptographically secure psuedorandom number
generators.

getentropy() is only intended for seeding random number generators and is
not intended for use by regular code which simply needs secure random
data. For this purpose, please use arc4random(3).

The maximum value for buflen is 256 bytes.

IMPLEMENTATION NOTES
getentropy() reads from the sysctl(7) variable kern.arandom.

RETURN VALUES
The getentropy() function returns 0 on success, and -1 if an error
occurred.

ERRORS
getentropy() will succeed unless:

[EFAULT] The buf argument points to an invalid memory address.

[EIO] Too many bytes were requested.

SEE ALSO
arc4random(3), rnd(4)

STANDARDS
The getentropy() function is non-standard.

HISTORY
The getentropy() function first appeared in OpenBSD 5.6, then in
FreeBSD 12.0, and NetBSD 10.

Explicitly use -fcommon for globals shared between libc and CSU.

Install new man-page devname_r(3).

This is a link to devname(3).

Add the new signalname/signalnext/signalnumber interface to libc.

This as discussed on current-users in the thread
entitled:
Proposal: new libc/libutil functions to map SIGXXXX <-> "XXXX"
that can be found (starting at):
http://mail-index.netbsd.org/current-users/2017/04/28/msg031600.html

These functions provide the mechanism to enable applications
to divorce themselves from internal details of the signal
implementation.

Libc minor bumped, prototypes in <signal.h>, sets lists updated (and sorted).

One and all: feel free to improve the sources & man page (etc), but
please do not change the function signatures without discussion.

Mark exect(3) obsolete and bind it to plain execve(2) on all platforms

The original exect(2) from BSD4.2 was enabling bit for tracing
(single-step mode) and calling execve(2). The purpose of it was to generate
a signal for a tracer once the application will change its image to a new
program.

This approach no longer works as:
- exect(2) traces (single-steps) libc and it requires hundreds or
thousands steps before entering a new image
- it's vax and x86 specific code
- this functionality has been moved to the kernel - once a process is
traced it will generate SIGTRAP with si_code TRAP_EXEC and route it to
its debugger
- the side effects and unportability make this interface unusable
- there are no known users of this interface
- it apparently never worked better since day0 of NetBSD ("day0 bug")

Users are requested to move to other execve(2) variants. Calling current
execve(2) as it is the most similar behavior to this one from BSD4.2.

Discussed several times on mailing lists and in PR/51700.

Add warning to exect(3) telling about marking this function obsolete.

This function is prepared to be removed in next libc major bump.

- syslog_ss.c *_ss api functions (don't use stdio, time)
- syslog.c: *syslog* non _ss api functions (use stdio, time)
- xsyslog.c> common guts.

The motivation for this is not to drag in stdio/locale/floating point/time
for every binary, since syslog_ss() is used in __stack_check_fail() for SSP.

Add timespec_get(3) in <time.h> and enable unconditionally struct timespec

These changes conforms to the C11 standard
References:
- 7.27.1/3 Components of time (struct timespec)
- 7.27.2.5 The timespec_get function

According to ISO/IEC 9899:201x (draft) <time.h> defines the timespec
structure and declares the timespec_get(3) function with TIME_UTC
definition.

According to a C++17 standard draft <ctime> offers the same interface in
the std:: namespace.

The timespec_get function modifies the timespec object pointed by ts
to hold the current calendar time in the given base. The standard notes
only the TIME_UTC base with implementation defined value, set it to 1
as zero is reserved for error handling. Once operation was successful this
function returns passed base, otherwise exits with zero.

The timespec struct was already part of the POSIX standard in <time.h>.

Enable this interface unconditionally in the header to allow to use it
in a code prior C11 and C++17 as an extension.

move manpages for frexp/ldexp/modf to libm -- the (most) implementation is
already there

First step to clean up the variety of frexp(), ldexp() and modf()
implementations.
Long term goal is to use the implementation in libm and get rid of
the libc instances. For now, we need to keep one in libc for compatibility,
it belongs into the compat subtree.
The switch is per-arch. Should be painless for ieee754 boxes.
If all ieee754 archs are switched, libc/gen/{frexp,ldexp,modf}_ieee754.c
can be removed.

64 bit inode changes

Both libcurses and libc installed a getcap(3) manpage, and both used it

last in install overwrote everything from the other camp.

function is really named "getcap" here.

document getgroupmembership(3)

Implement getgroupmembership(3). This is similar to getgrouplist(3), except
that the "int maxgroups" and "int *ngroups" parameters are separated into
two separate parameters which makes it possible to call multiple nsswitch
back-ends and have the results correctly merged.
getgrouplist(3) is now implemented using getgroupmembership(3).

It tells you the major device number for whatever character or block

information) and not a database cobbled together from the contents of
the filesystem.

Renamed sys_errlist[] and sys_nerr to __sys_errlist[] and __sys_nerr.
The traditional API of sys_errlist[] and sys_nerr is provided by weak
references if they are supported. Otherwise, we're forced to have to
have two copies of the error message string table in the library.
Fortunately, unless a program uses both sys_errlist[] and strerror(),
only one of the copies will be linked into the executable.

This is all to provide an clean namespace as required by ANSI. I've
done the same for sys_siglist[], even though it is not required, to
be consistant.

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif

* Add more compat #defines and autoconf-checked functions.

Add hooks to make this compilable from src/tools/compat.

Readd my change from fts.c rev 1.10, which was incorrectly removed in rev 1.19

Adjust fts_pow2() for LP64 before Ross bricks me.

GC one line of unneeded code.

Fix the comment above fts_palloc().
Also, fail with ENOMEM if fts_pathlen would overflow, rather than silently truncating the
path.

Avoid memory leaks when realloc() fails (by storing the return value in a temporary, and
testing it before assigning it; fts_close(3) will deallocate the old memory).

Fix multiple problems in the FTS_NOCHDIR case:
* There was an off-by-one error that caused the addition of a NUL or slash in fts_build() to
overwrite other memory.
* After fts_palloc(), we need to reset `cp' so that it points to the new path name buffer;
otherwise the addition of the file name before calling fts_stat() could lose.
Also, fix stupidity in the fts_palloc() interface. We don't want N bytes more than the
current buffer size; we want N bytes more than the current length. Just pass in the new
size, since we can't figure it out easily here.

Allocate the path name buffer by powers of 2.

Minor change to previous.

Fix 3 bugs:
* When not using FTS_NOCHDIR, fts_accpath == fts_name. fts_padjust should not
try to move fts_accpath in this case.
* Previous entries at the same level also need to be adjusted.
* A bug was introduced in rev 1.8 (HI CHRISTOS!!) that caused the maxlen
comparison to always fail (due to type promotions) when sp->fts_pathlen ==
cur->fts_pathlen -- thus causing memory stompage.

back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

_DIAGASSERT(path != NULL)

fix bug introduced in rev 1.8 during delint(1)ing which broke globbing ~/
(hi christos! ;)

Warn about references to the old glob functions, and direct the user to
include <glob.h> to generate the correct references.

Suggestion from Christoph Badura.

delint! -- actually fix a bug lint found, globtilde could never have worked...

const poisoning.

* Remove GLOB_QUOTE, add GLOB_NOESCAPE. Per POSIX, backslash quoting of
special characters is the default behaviour, which may be disabled by
setting GLOB_NOESCAPE.
* If no matching pathnames have been found and GLOB_NOCHECK was not set
(or special csh(1)-specific treatment of magic characters was requested),
return GLOB_NOMATCH instead of 0; the latter would indicate a successful
operation.
* Use strcoll() instead of strcmp() to sort globbed pathnames.

Replace the old GLOB_ABEND constant with (the standardized) GLOB_ABORTED.

remove obsolete register declarations

Allow the old-name functions to be compiled from the same source file as
the renamed functions, and add some #error directives to force the
issue with weak symbols for renamed functions when we support weak
symbols in the C library.

On platforms where we can use weak aliases, use
__weak_alias(__errno, __errno_func);
and on platforms where we cannot, just compile the function as
__errno, since on those platforms we cannot make libc thread-safe,
at least using this trick.

Are there any platforms where we cannot do __weak_alias() anymore?
