* configure.ac: Bump LT version to C3/A3/R0.

At some point in the past we introduced a regression in that the
client of a pipe server received its own pid and not the pid of
the server.

* src/assuan-pipe-connect.c (struct at_pipe_fork)
(struct at_socketpair_fork): Add PARENT_PID.
(at_pipe_fork_cb, at_socketpair_fork): Use PARENT_PID instead of getpid.
(pipe_connect, socketpair_connect): Set PARENT_PID.

* src/vasprintf.c (checkit): Set flag for a test failure.
(main): Return error on any failure.

* build-aux/gitlog-to-changelog: New script.  Taken from gnulib.
* build-aux/git-log-fix: New file.
* build-aux/git-log-footer: New file.
* doc/HACKING: New file.
* ChangeLog: New file.
* Makefile.am (EXTRA_DIST): Add new files.
(gen-ChangeLog): New.
(dist-hook): Run gen-ChangeLog.
* autogen.sh: Install commit-msg hook for git.

Rename all ChangeLog files to ChangeLog-2011.

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

- Libtool is now at version 2.4.
- Fixed the newer autoconf warnings.
- Updated config.{guess,sub} to a more modern version; we used a 4 years
  old version.

Also enhanced the m4 test marcos and removed some cruft.

This fixes bug#1328 (libassuan: ce-server fails to compile on Darwin
due to missing include).

Let an existing command previously registered with assuan_register_command() be updated with new values. This fixes overriding the HELP command for example.

Improved gpgcemgr
