- remove dependency on gpg-offline, source validator already
does that

- Version bump to 0.9.34:
* Drop tls patch seems to build fine
* Remove code for other distros we build against 13.1+ anywhere
within obs and it just clutters the spec.
* Explicitely name switches in configure to make sure things go
the desired way.
* Fix install of libmicrohttpspdy pc file.
+ Added support for TCP FASTOPEN.
+ Removed dependency on plibc for simpler compilation for W32.
+ Added configure option "--disable-pipes" to use socketpairs
instead of pipes for signalling to child threads. Pipes are
always disabled on W32.
+ Corrected some uses of 'int' vs. 'size_t'.
+ MHD_USE_DUAL_STACK in libmicrohttpd currently just *inhibits
setting* the IPV6_V6ONLY socket option, but per Microsoft's
documentation the default on Windows is that this is enabled, thus
MHD_USE_DUAL_STACK will not work (since it leaves the
default). libmicrohttpd should probably just unconditionally set
IPV6_V6ONLY to the desired value when the option is available.
+ Allow Keep-Alive with HTTP 1.0 (if explicitly requested),
and automatically set "Connection: Keep-Alive" in response
in this case as well.
+ Adding explicit annotations to hide symbols that are not for
export in the C code (gcc 4.0 or higher only).
+ Adding a few lines to avoid warnings from picky compilers.
- Added patches:
* libmicrohttpd-0.9.34-spdy-pc.patch
