(_assuan_sock_bind): Create a Cygwin socket file depending on a socket
flag.

This code has not been tested.

* src/assuan-inquire.c (assuan_inquire): Clear return args on error.
Read up remaining lines after MAXLEN has been hit.
--

If we would stop immediately at MAXLEN, as we did, the client would
continue to send data which the server may consider as new Assuan
commands.

* configure.ac (BUILD_TIMESTAMP): Set to "<none>" by default.
--

This is based on
libgpg-error commit d620005fd1a655d591fccb44639e22ea445e4554
but changed to be disabled by default.  Check there for some
background.

* src/assuan-defs.h (wipememory2, wipememory): New.  Taken from GnuPG.
* src/assuan.c (assuan_release): Wipe the context.
--

The assuan context has buffers which may carry senitive information.
These buffers could be wiped out with each flush but that is too
expensive.  Thus we only wipe them when freeing the context.

(assuan_sock_set_flag): New.

* src/libassuan.vers: Add them.
--

These new functions are intended for a Cygwin socket emulation.  This
commit merely introduces a generic framework.

* src/assuan-defs.h (_assuan_error): Use error source Assuan if no CTX
is given.

* src/assuan-buffer.c (assuan_sendfd): Check that CTX is not NULL.
(assuan_receivefd): Ditto.
--

This change is to align the behaviour with that of assuan_send_data.

* doc/assuan.texi (assuan_inquire): Fix and improve description of
this function.

--

* doc/assuan.texi: fix documentation

--

Reading up on assuan to create python bindings uncovered a few bugs in
the documentation.

* src/Makefile.am (extra_ltoptions): New.
(libassuan_la_LDFLAGS): Use it.
--

Since gcc 4.8 there is a regression in that plain C programs may link
to libgcc_s.a which has a dependency on libgcc_s_sjlj.dll.  This is
for example triggered by using long long arithmetic on a 32 bit
Windows (e.g symbol __udivdi3).

This patch does not change anything right now but we add it anyway
in case long long will ever be used.

* configure.ac (AM_INIT_AUTOMAKE): Add serial-tests.
* src/Makefile.am (INCLUDES): Rename to AM_CPPFLAGS and remove the
nonexistent ../include/.

* src/assuan-socket-connect.c (assuan_socket_connect_fd): Map fd to
assuan_fd_t.
--

This function is actually not used by GnuPG.  The function should have
taken an assuan_fd but given that it did not we use our usual mapping
from Windows libc fds to an assuan fd.

* src/debug.h: Remove traling ", 0" expression part where not useful.
--

gcc 4.9 detected this.  Probably taken from gpgme but used
differently.

* src/w32-sock-nonce.inc.h (EADDRINUSE): Avoid redefining.
* src/assuan-socket.c (_assuan_sock_bind): Set error to EADDRINUSE.
--

With the latest mingw-w64 EADDRINUSE is defined but to a different
value than WSAEADDRINUSE.  We need to use EADDRINUSE becuase that is
what applications expect.

* configure.ac: Set LT version to C5/A5/R0.
(AM_INIT_AUTOMAKE): Add options.
* Makefile.am (AUTOMAKE_OPTIONS): Remove.

* src/assuan-socket.c (eval_redirection): Stop parsing at the first
LF.
--

Avoiding LFs in file names is better for logging.

* configure.ac (AC_CHECK_FUNC): Check for stat.
* src/assuan-socket.c (SUN_LEN): Add.
(eval_redirection): New.
(_assuan_sock_connect) [!W32]: Implement socket file redirection.
(_assuan_sock_set_sockaddr_un): New.
(assuan_sock_set_sockaddr_un): New.
--

This feature is useful to allow sockets with standard names even on
file system which do not supports socket and to help with shared home
directories.  For example to use GnuPG 2.1 with shared home
directories one will be abale to do:

 rm ~/.gnupg/S.gpg-agent || true
 printf "%%Assuan%%\nsocket=${HOME}/.gnupg/S.gpg-agent_${HOSTNAME}\n" \
       > ~/.gnupg/S.gpg-agent

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.
