61c68000ed avcodec/mjpegdec: Add some sanity checks to ljpeg_decode_rgb_scan()
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.

36cd017acd avformat: make avformat_close_input() more tolerant.
The purpose of this commit is to make error management simpler and less
error prone, just like av_free() which is safe with NULL.

d5b58f678d tools: add benchmark for crypto functions.
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.

35cbc98b72 alac: Check that the channels fit at the given offset
The code tries to decode a number of channels at the
offset given by the ff_alac_channel_layout_offsets table.
Even if the number of channels decoded so far doesn't
exceed the total number of channels, we need to check that
we actually can decode that number of channels at this offset
as well.
