676d380f2a Fix undefined behavior in ffv1 with insane widths.
The new tables is large enough to prevent this together with our image size checks.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

3224079956 optimize init_vlc().
Reduce worst case time from O(N^2) to O(N*log(N)).
Speedup average case by a factor of 10 in ffv2 (total decoding speed +4-25%),
factor of 1.3 in ffvhuff (total +0.5%),
factor of 1.8 in indeo5 (total +1%),
factor of 1.1 in mjpeg (total +0.1%).

4c4e746566 Avoid negative shifts in build_table()
A shift by a negative amount has undefined behaviour.  Even though
the result of this shift is never used, the shift itself could
cause an exception of some kind.

ef530829f8 Remove ff_realloc_static, it is no longer used and since it was declared
static there is no reason to wait for a major version bump, removing
it does not change ABI in any way, not even the non-public one.

ec62d942ea Fix potentially unaligned accesses in ff_copy_bits()
A pointer should never be assigned a value which may have less than the
required alignment of the target type.  Compilers may assume pointer
values have the required alignment, and emit normal load/store instructions.

Unaligned pointers should use a character type or compiler-specific
type modifiers.
