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. Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>

The reader reads in chunks of 11 bits at most, and at most 3 times. The unsafe reader therefore may read 6 chunks instead of 1 in worst case, ie 8 bytes, which is within the padding tolerance. The reader ends up being ~10% faster. Cumulative effect of unsafe reading and code block swapping on 3 sequences is for 1 thread, decoding time goes from 23.3s to 19.0s.

The old code was reserving the 0xFFFF entry to represent an inexisting entry/codeword. These entries are now detected through their length being <= 0. As this entry is often used for the residuals (-1,-1), which should be among the most frequent, it is particularly important to not reserve it. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

The effect is not really deterministic, as it seems to be a combination on x86_64 of fewer registers used, different jump offsets and, for all archs, of likely branches. Speedup is around 15%. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

When the joint table does not contain a valid entry, the decoding restarts from scratch. By implementing the trick of jumping to the 2nd level of the individual table (and inlining the whole), a speed improvement of 5-10% is possible.

Almost all of the code is shared so there is little point in enabling one decoder/encoder without the other.
