Revert CC_WNO_USE_AFTER_FREE from Makefile's (thanks uwe@)

Sprinkle CC_WNO_USE_AFTER_FREE for GCC 12

All of them are blamed for idiom equivalent to:
newbuf = realloc(buf, size);
p = newbuf + (p - buf);

install pkg-config file for libedit

version number matches portable libedit
--cflags output matches portable libedit, since users probably want the
readline interface

bsd.own.mk: rename GCC_NO_* to CC_WNO_*

Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.

GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

introduce some common variables for use in GCC warning disables:

GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

branches: 1.65.6;

Allow wide characters (properly encoded as byte strings according to LC_CTYPE)
to be (perhaps part of) the "invisible" characters in a prompt, or the
required prompt character which follows the literal sequence (this character
must be one with a printing column width >= 1). The literal indicator
character (which is just a marker, and not printed anywhere) (the PSlit
parameter in sh(1)) can also be a wide char (passed to libedit as a wchar_t,
encoded as that by sh(1) or other applications that support this.)

Note: this has currently only been tested with everything ascii (C locale).

add literal escape sequence support, patterned after the tcsh ones.

new man page from Ingo Schwarze.

From Ingo Schwarze:
* Replace fcns.c by a shorter and simpler func.h
and include it only in the one file needing it, map.c.
* Combine help.h and help.c into a simplified help.h
and include it only in the one file needing it, map.c.
* Check the very simple, static files editline.c, historyn.c, and
tokenizern.c into CVS rather than needlessly generating them.
* So we no longer autogenerate any C files. :-)
* Shorten and simplify makelist by deleting the options -n, -e, -bc,
and -m; the latter was unused and useless in the first place.
* Move the declaration of el_func_t from fcns.h to the header
actually needing it, map.h. Since that header is already
included by el.h for unrelated reasons, that makes el_func_t
just as globally available as before.
* No longer include the simplified fcns.h into el.h,
include it directly into the *.c files needing it.

Start removing the WIDECHAR ifdefs; building without it has stopped working
anyway. (Ingo Schwarze)

re-enable -Wconversion

Only use -Wconversion if GCC is actually the active compiler.

Don't use "-Wconversion" with GCC 4.5 which will complain about all the
expressions where signed variables are converted to unsigned in an
expression e.g. "size_t foo = sizeof(something) * int_var;".

Is that the right way? Perhaps WARNS=5?

Rename key to keymacro to avoid conflicts with term.h. The renaming of term

Fix wide build, test it, but don't turn it on yet.

Wide character support (UTF-8) from Johny Mattsson; currently disabled.

WARNS=4

Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the
FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to
various string and memory copy and set functions (as well as a few system
calls and other miscellany) where known at function entry. RedHat has
evidently built all "core system packages" with this option for some time.

This option should be used at the top of Makefiles (or Makefile.inc where
this is used for subdirectories) but after any setting of LIB.

This is only useful for userland code, and cannot be used in libc or in
any code which includes the libc internals, because it overrides certain
libc functions with macros. Some effort has been made to make USE_FORT=yes
work correctly for a full-system build by having the bsd.sys.mk logic
disable the feature where it should not be used (libc, libssp iteself,
the kernel) but no attempt has been made to build the entire system with
USE_FORT and doing so will doubtless expose numerous bugs and misfeatures.

Adjust the system build so that all programs and libraries that are setuid,
directly handle network data (including serial comm data), perform
authentication, or appear likely to have (or have a history of having)
data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default,
with the exception of libc, which cannot use USE_FORT and thus uses
only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no
per-directory or in a system build will disable if desired.

Rename TEST/test.c to avoid problems when doing a cleandir on case-insensitive
file systems.

MAKEVERBOSE support

Libedit depends on libterm. From Patrick Welche

Make everything that uses makelist depend on Makefile - that way the
created files pick up new entries.

Separate out the filename completion functions from the readline() code.
Pass in loads of parameters instead of relying on shed-loads of global
variables to modify the behaviour.
The filename completion code can now be enabled by code that uses el_gets().
(eg /bin/sh)

Tokenization function enhancements:
* Make tok_init(), tok_end(), tok_reset(), tok_line() and tok_str()
publically available in <histedit.h>
* Documented the public functions in editline(3)
* Renamed tok_line() -> tok_str()
* Added new tok_line() which takes a "const LineInfo *" instead of
"const char *" (the former has "cursor" information), and optionally
return the argv index ("int *cursorc") and offset within that index
("int *cursorv"). This means that completion routines can use the
tokenization code to crack the line and easily find which word the
cursor is at. (mmm, context sensitive completion :)
* Fixed TEST/test.c when using "continuation" lines (unmatched quote
or \ at EOL), and added some more DEBUG messages including highlighting
where the cursor is (with a `_').

Rework how dependency generation is performed:

* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

tweak this unconventional (some might say "baroque") Makefile to work
with the new <bsd.dep.mk> *.d semantics.

vi mode and memory fixes from david laight.

Explicitly move setting of NOxxx and USE_SHLIBDIR to the top of the
Makefile (before including <bsd.own.mk>)

Add a couple linted comment and enable WARNS=3

* Add user-controlled mk.conf variables
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".

- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.

- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so

2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so

3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed

Standard location of readline headers is /usr/include/readline/, so install
them there.
readline.h of libedit had to move to subdirectory 'readline', due to the way
BSD makefiles work; this is better than potentially fragile Makefile hacks

use .tmp temporaries for generated files, to avoid having failed generated
output being used.

Use LIBEDITDIR instead of CURDIR so we can use that Makefile to compile
libedit from another directory.

More trailing white space.

Add minimal dependency to make "make depend" optional
after cleandir.

* add more checks for NULL pointers in passed arguments
* implement el_get(EditLine *, int op, void *result), which does the
inverse of el_set()
* add EL_EDITMODE operation to el_set and el_get; if non zero editing
is enabled (the default).
* add "edit on | off" editrc command, which modifies EL_EDITMODE.
users can now add '*:edit off' in ~/.editrc as an advisory to
disable editing.

NOTE: at this time EL_EDITMODE is just an indication of the
state of the 'edit' command. It's up to the application to check
this after el_source() or el_parse() to determine if editing is still
required.

Build readline.o into debugging versions of libedit, too.
