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.

static there is no reason to wait for a major version bump, removing

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.
