Michael Niedermayer 274a50ab57 avcodec/utils: Warn the user about the lack of a lock manager if insufficient locks are detected 
A lock manager is not the only possibility to avoid open/close locking
issues but its easier and more robust than maintaining a lot of lock/unlock
calls.

Michael Niedermayer fe328f0807 avfilter: Dont partially merge lists 
This prevents the unneeded insertion of multiple aresample filters in some cases

The format merging is moved to avoid having to call the channel layout
merge twice. The channel layout merge code uses different structures and
is not compatible with the added dry run wrappers.

This is similar to int32_to_float_fmul_scalar, but
loads a new scalar multiplier every 8 input samples.
This enables the use of much larger input arrays, which
is important for pipelining on some CPUs (such as
ARMv6).
