059a037fbd AVOptions: split get_number().

instead of options and have consistent naming and signatures.

641c7afe3c AVOptions: add new API for enumerating children.
This will allow the caller to enumerate child contexts in a generic way
and since the API is recursive, it also allows for deeper nesting (e.g.
AVFormatContext->AVIOContext->URLContext)

This will also allow the new setting/reading API to transparently apply
to children contexts.

88d1e2b2b0 intfloat_readwrite: fix signed addition overflows
These additions might overflow the signed range for large
input values.  Converting to unsigned before the addition
rather than after avoids such undefined behaviour.  The
result under normal two's complement wraparound remains
unchanged.

c8d787d2ef AVOptions: split av_set_string3 into opt type-specific functions
Also stop attempting to honor the alloc parameter, as things break
horribly in that case.
It will be removed in upcoming successor to av_set_string3.

8b19ae0761 crc: fix signed overflow
This fixes a signed overflow from i << 24 when i == 255 by
making i unsigned.  The result of the shift is already
assigned to an variable of unsigned type.

b3e144a7df des: add possibility to calculate DES-CBC-MAC with small buffer
This patch adds the possibility to calculate the DES-CBC-MAC of a
source buffer (i.e. the last block of the buffer encrypted in CBC
mode) without having to allocate a destination buffer that is as
long as the complete source buffer, but instead only 8 bytes
for the MAC.

a726d7fd4e AVOptions: in av_opt_find() don't return named constants unless unit is specified.
That is, unless the caller explicitly asks for them.

Prevents conflict between e.g. the 'loop' option in img2 demuxer and
'loop' flag in AVCodecContext.
