'k', 'M', and 'G' are SI (unit) prefixes or metric prefixes,
not 'number postfixes'. Also, the statement regarding binary
prefixes ("powers of 2 are used instead of powers of 10")
might be misinterpreted (1 kB = 10^3 B, but 1 KiB != 2^3 B).

configure: suncc: Add compiler arch support for Nehalem & Sandy Bridge
GCC does not appear to have a -march= string for Westmere, which is a
bit surprising as it has a few more instructions than a Nehalem, but
a few less than a Sandy Bridge.

av_memcpy_backptr: optimise some special cases
- Add special cases for offsets of 2, 3, or 4 bytes. This means the
offset is always >4 in the generic case, allowing 32-bit copies to
be used there.
- Don't use memcpy() for sizes less than 16 bytes.
Note that tag_bytes is unsigned, which makes the right-hand side of
`tag_start = ...' unsigned, too. The 32-bit unsigned value is then
zero-extended to 64 bits. Therefore, tag_start must be non-negative,
and the check (tag_start < 0) is always false, which breaks the error
handling. This patch fixes the check.

pcm: fix decoding of pcm_s16le_planar on big-endian
The sample count is decremented by the DECODE() macro and needs to be reset
in each loop iteration. Also, DECODE() increments the src pointer so that does
not need to be done separately.

If there are any samples remaining in the output fifo from previous conversion

Use a different char* for extracting info string from the URL. The

avserver: remove daemon mode
This code spews a multitude of warnings with glibc (unchecked

the deamonisation is not suitable for use with typical startup

Users wishing to run avserver as a daemon can still do so using
start-stop-daemon or equivalent tools.
