* configure.ac: Set LT version to C4/A4/R2.

* autogen.sh: Add --find-version stuff.  Taken from GnuPG.
* configure.ac: Change accordingly

--

* src/context.c (assuan_set_error): Do not pass NULL for %s in the
trace function.
--

This likely fixes
GnuPG-bug-id: 1659

* src/debug.c (_assuan_debug): Check wether CAT want to be logged.

* src/debug.h (TRACE_ERR): Check CTX before a deref.
* src/assuan-defs.h (_assuan_error): Turn into an inline function and
check CTX before a deref.
--

Found by Hans-Christoph Steiner with cppcheck.

* autogen.rc: New.
* Makefile.am (EXTRA_DIST): Add it.
* autogen.sh: Update from GnuPG.

* compile, config.guess, config.rpath, config.sub, depcomp, ltmain.sh
* doc/mdate-sh, doc/texinfo.tex, install-sh, missing: Move to
build-aux/.
* Makefile.am (EXTRA_DIST): Remove config.rpath - it is implicitly
distributed.
* configure.ac (AC_CONFIG_AUX_DIR): New.
(AM_SILENT_RULES): New.

--

This is the version from current libgpg-error which already has the
changes done here plus these:

  bf0d67db * Update libtool to support Android.
  dd05f379 * Fix libtool 2.4.2 to correctly detect .def files.
  6971fe55 * Update to libtool 2.4.2.

* config.guess, config.sub: Update to latest version (2013-11-29).
* m4/libtool.m4: Add patches for ppc64le.
--

We don't want to update libtool, thus we use patches supplied by IBM.

--

* configure.ac: Set LT version to C4/A4/R1.

* configure.ac (have_dosish_system): Set for W64.
* src/assuan-defs.h (SOCKET2HANDLE, HANDLE2SOCKET): Add versions for
W64.
* src/assuan-handler.c (assuan_command_parse_fd) [W64]: Use strtoull
to parse an FD.
--

Note that these changes are not complete but merely sufficient to
allow building of GpgEX.

* ltmain.sh: Prefix the SO number for W64 with a "6".
--

We need to stick to libtool 2.4.2 anyway, thus we take the easy way
and hack libtool instead of adding "-release 6" to the Makefile.  This
also avoids an extra dash before the 6 and thus yields a prettier name
than the one produced by the -release option.  The header files and
def files are supposed to be identical for w32 and w64 thus we don't
need to do any special code for them.

Having a different namespace for 64 bit DLLs is such a good idea that
I hope this or a similar feature will be provided by future libtool
versions.

--

* configure.ac: Bump LT version to C4/A4/R0.

* src/assuan.c (assuan_check_version): New.
(digitp, parse_version_number, parse_version_string)
(compare_versions): New.  Taken from libksba.
* configure.ac (VERSION_NUMBER): New ac_subst.
* src/Makefile.am (assuan.h): Pass VERSION and VERSION_NUMBER to
mkheader.
* src/assuan.h.in (ASSUAN_VERSION, ASSUAN_VERSION_NUMBER): New macros.
(assuan_check_version): New prototype.
* src/libassuan.def, src/libassuan.vers: Add assuan_check_version.
* src/mkheader.c (write_special, main): Support version and
version_number.
* tests/version.c: New.
* tests/Makefile.am (TESTS): Add version.
--

All our other libs have a version number check, thus we should have
one in Libassuan as well.

* src/system-w32.c: Do not include windows.h here.
--

winsock2.h must now be included before windows.h.  This is already
properly handled by assuan-defs.h.

* configure.ac (BUILD_TIMESTAMP): Use an ISO date string on all
platforms and ac_define it.
* src/sysutils.c (_assuan_sysutils_blurb): But revision and build date
into the binary.
--

An ISO date is for sure better than the old C standard time format.
An almost all platforms this should work.  We don't print the seconds
to be compatible with the way we did in on Windows.  However we print
in UTC.

* src/system-w32ce.c (__assuan_write, __assuan_recvmsg)
(__assuan_sendmsg, __assuan_waitpid): Make functions global.
* tests/ce-server.c: Fix syntax error (s/#else/#endif)
--

This patch fixes some cruft which has accidentally been introduced
over time.  The code builds, but due to a lack of ready to use CE box,
I was not able to test it.

* autogen.sh (build-w32): Include {amd64,w32_toolprefixes).
--

Note that despite of the support in autogen.sh and possible other
places, there is no W64 support yet.

* configure.ac: Update to modern git version checking.  Remove svn
support.
* src/versioninfo.rc.in: Update copyright years.

* m4/gpg-error.m4: Update from current gpg-error git.

* compile, config.guess, config.rpath, config.sub, depcomp,
* install-sh, mkinstalldirs: Update to current versions from gnulib.
--

Some of them have not been updated here in over 8 years, time to fix
that.

* src/client.c (assuan_transact): Send an CAN after an error return
from the inquiry callback.

* configure.ac: check for getpeerucred() which (Open)Solaris/SunOS
uses.
* src/assuan-socket-server.c (accept_connection_bottom): make use
of getpeerucred().

* configure.ac: check for LOCAL_PEEREID and getpeereid().
* src/assuan-socket-server.c (accept_connection_bottom): make use of
LOCAL_PEEREID and getpeereid().
--

For use with assuan_get_peercred(). Note that getpeereid() does not
set the PID member. LOCAL_PEEREID is checked before getpeereid()
since NetBSD has both of these. SO_PEERCRED is still checked first.

[Second revision]
This revision adds support for LOCAL_PEEREID which NetBSD uses. Its
tested against NetBSD 6.0 and may work without problems with earlier
versions. FreeBSD uses getpeereid() which does not have PID support.
Recent OpenBSD versions do support SO_PEERCRED and old versions have
getpeereid() but also may have LOCAL_PEEREID (not sure).

* configure.ac (mmm4_revision): Use git rev-parse.  Print version
information at the end of a configure run.

* autogen.sh: Remove option -c from chmod.
