4cabef0a9d Make strmatch() return 1 only if the string compared against the 
prefix does not contain other characters which may belong to an
identifier.

This allows to distinguish for example to have different constants
with the same prefix (e.g. "foo" and "foobar").

3fc548df28 Make ff_inverse stay with libavutil, and optional copy it to libavcodec. 
The ff_inverse table is used by FASTDIV macro, defined in libavutil, but up
to now the table was defined only in libavcodec.

After this change, the main copy of ff_inverse is part of libavutil (just
like FASTDIV), but if CONFIG_SMALL is unset, then a different copy is made
available to libavcodec, to avoid the performance penalty of using an
external look up table.

Dynamic linking works, because the libraries are linked with -Bsymbolic, so
the local copy of the symbol has priority over the external; static linking
works because the table is on a standalone object file in both libraries,
so the linker is able to discard one of the two.

Tested on Linux/x86-64 and Mac OS X/x86-64.

b7fa5c5abb random_seed: allow to block on /dev/random 
If both /dev/random and /dev/urandom failed to return data, an
uninitialised value might be returned.  Since most systems have a
non-blocking /dev/urandom or have /dev/random with similar properties,
the chance of blocking is minimal, and the alternative of returning
non-random data is worse.
