These prevent the rgb ljpeg code from being run on parameters that it doesnt
support. No testcase available but it seems possible to trigger these.

Sorry, I'm too lazy to fix the rest.

See previous commit.

The purpose of this commit is to make error management simpler and less
error prone, just like av_free() which is safe with NULL.

This ensures that no uninitialized bytes cause non-deterministic behavior.

This allows creation of frame accurate chapter marks from sources like
DVD and BD where the precise chapter location is not known until the
chapter mark has been reached during reading.

Prevent an invalid free in case of init failure.

Fix trac ticket #2930.

Some parts of the code have been known to react badly to
empty frames; they should not, but there is no need to
take risks.

The benchmark tests the speed of the following algorithms:
MD5, SHA-1, SHA-256, SHA-512, RIPEMD-160, AES-128.

It can optionally be built to perform the same benchmark on
other crypto libraries, for comparison purposes.
The supported libraries are:
- crypto:   OpenSSL's libcrypto;
- gcrypt:   GnuTLS's libgcrypt;
- tomcrypt: LibTomCrypt
To enable them, use this syntax:
make VERSUS=crypto+gcrypt+tomcrypt tools/crypto_bench
They do not need to have been enabled in configure.

It uses at least sin()

"into the doc/examples directory" vs "into doc/examples".

Currently all uses of the emu edge code as well as the code itself
assume int linesize
changing some but not changing all would introduce a security issue
once all use this typedef a simple search and replace can be
done to switch them all to ptrdiff_t

This makes sure that linesize * start_y doesn't overflow, so that
emulated_edge_mc can get back the original value if needed.
