When compiled with --disable-pthreads, e.g
http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7,
a bunch of -Wunused-functions are reported due to missing header guards
around threading related functions.
This patch should silence such warnings.

Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE.
The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros.
This solution is on the lines of the one in commit af181827.

Silence an incompatible-pointer-types-discards-qualifiers warning from clang.
rangecoder.c:58:34: warning: passing
      'uint8_t **' (aka 'unsigned char **') to parameter of type
      'const uint8_t **' (aka 'const unsigned char **') discards qualifiers in
      nested pointer types [-Wincompatible-pointer-types-discards-qualifiers]

The intended meaning is "if this block is the first block in a slice then
its left boundary is a slice boundary". Silence a logical-not-parentheses
warning from gcc.

Silence a warning due to frame assignment in dvenc. All uses of the
reference in dvdec are read only, except the ones in the main decoding
function, so use the frame pointer directly there.
