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.

ce1cd1cba2 Rename read/write_line() to av_read/write_image_line(). 
The old names were not av_ prefixed, and they were causing linking
failure on many platforms.  The new names are also more descriptive.

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.

dd025f25da Change AES code to be strict-aliasing-safe. 
Makes it give correct results with e.g. gcc 4.4.
For unknown reasons the generate asm code also changes
on e.g. gcc 4.3, making the code a bit larger but also
a bit faster.
