Upstream version 2.2.1

--

* doc/assuan.texi: fix documentation

--

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

Upstream version 2.2.0

debian/patches/0001-Use-the-debian-changelog-timestamp-for-BUILD_TIMESTA.patch: Patch to use the debian/changelog date for BUILD_TIMESTAMP to make build reproducible.

* 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

* configure.ac: Set LT version to C4/A4/R3.

* src/system-w32.c (__assuan_read): Retry using select.  Map
WSAECONNRESET to EPIPE.
(__assuan_write): Retry using select.
* src/assuan-buffer.c (readline) [W32]:  Return EOF instead of EPIPE.
