rpc_errlist:
- add some missing error numbers.
- while i'm here, use c99 initializer.
clnt_sperrno:
- handle NULL in rpc_errlist as it's now sparse.

change 'char *' args of clnt_pcreateerror, clnt_spcreateerror,
clnt_perror, and clnt_sperror to 'const char *' to follow manual
pages (!!).

Add new RPC code, based on Sun's TI-RPC code. Adapted to not use XTI,
but sockets instead, internally. Old, backward compatible interfaces
maintained.

branches: 1.23.2;
Delint.
Remove trailing ; from uses of __weak_alias(). The macro inserts this if
needed.

fix use of uninitialized "buflen" (botched in 1.18), closes PR lib/9104
by bgrayson@ece.utexas.edu

Fix incorrectly initialized value from _DIAGASSERT() changes.

branches: 1.20.2;
back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.

since clnt_p*error() are expected to print an error message, print one if they're called with dodgy args. ;)

* 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)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif

int -> size_t

* ensure memory is released if operations fail (in authunix_create(),
xdr_callmsg(), xprt_register(), svc_tcp(), svc_udp(), etc)
* don't attempt to close a socket filedescriptor if it's -1 (some from
freebsd, some i found)
* make the initial xid a little more random (from freebsd)
* fix some spelos and tyops in comments (some from freebsd)
* use warn() instead of warnx() for many errors; the user probably
wants to know what the error code was.
* knf & whitespace nitpicks

delint

* in get_myaddress(); always return sockaddr_in containing localhost:PMAP_PORT.
(as recommended in Weiste Venema's portmap5_beta distribution)
* deprecate register
* use memmove instead of bcopy
* KNF includes
* use err/warn() instead of perror/fprintf(stderr,)
* fix some typos

revert; we can't break the existing ABI and API

major cleanup (to sync with changes made in include/rpc/*.h):
* use int32_t, size_t, in_port_t instead of long, u_int, u_short as appropriate
* use uid_t and gid_t instead of int
* KNF, fix typos and spellos
* use const as appropriate
* deprecate register
* use memmove instead of bcopy
* use err/warn()

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.

This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.

Fix printf format strings.
Fix RCSID's
Fix gcc warnings
Add missing prototypes

- convert unsafe strcpy(), strcat() and sprintf() to the `n' versions.
- some KNF.

branches: 1.8.2;
Changed clnt_{s,}p{errno,error,createerror} so that the functions that
output emit newlines and those that return a pointer to string do not
append them.

The existing behavior was inherited from RPC4.0, but this seems to have
been corrected sometime before SunOS 4.1.

The documentation has been updated to reflect the new behavior.

fix typo(?): rpc__errlist usage shouldn't have had two underscores.
Also, cast return types to (char *) to quiet compiler's complaints about
loss of 'const'-ness.

Changed auth_errmsg() and clnt_sperrno() to access error messages
directly instead of by linear search.

save my sanity; stop using Id.

Added \n to end of format strings used by all the perror-like functions.
Added const qualifier to array of error strings.

be much more careful with types, and add prototype everything.

Don't bother checking if errno is in range --- strerror() already does
that.

move the rpc code into libc
