ce20edb7bd Vorbis-in-Ogg: Do not set timebase to invalid values 
Avoids an assert when the sample rate is invalid and the timebase
is thus set to e.g. 1/0.
Sample file is http://samples.mplayerhq.hu/ogg/fuzzed-srate-crash.ogg

This is a quick fix for a crash, not a final solution.

e5262ec44a Optimize C version of ff_emulated_edge_mc(). 
From ~780 cycles to 551 cycles, mostly just by using libc memcpy()
instead of manually shuffling individual bytes around.

362d8f7d9e os_support: make poll() fallbacks conditional on CONFIG_NETWORK 
poll() is only used by networking code, so the fallback should
only be built if networking is enabled.  Also remove CONFIG_FFSERVER
condition from the declarations.

This should fix building on systems without poll(), broken
by a8475bbdb6.

a7827a17c6 In mpegts "reserved_future_use" field must be set to 1 in SDT table 
According to EN 300 468 section 3.1 (Definitions):

   Unless otherwise specified within the present document all
   "reserved_future_use" bits is set to "1".

This was not the case for SDT generation so this patch fixes it.

3e5bc7ff6a In the start_frame() debug log, print the reference pos value rather than the evaluated value converted to int. 
That's required because -1 is evaluated as NAN, which converted back
to int looks like a random number, this is especially annoying when
debugging sources with undefined pos (as the video4linux2 device).
