No need to invoke vlc-config to expand a shell variable.

The lock is static anyway (and so is the data).

This is really poor implementation, but it is not really used.

 * No recursion within the VLC threading functions.
 * No need to care about VLC cancellation.

The overhead is negligible, and this avoids depending on the message
bank.

This saves over 1kb in libvlccore. This object was found with:

As blocks are in coding orders, calling ES_OUT_SET_PCR at each blocks increase to trigger ES_OUT_RESET_PCR.
The reference blocks should be in chronological order though.

The release of the block only makes sense if the edition is ordered.

This is the 12-bits logarithmic found on digital magnetic tapes,
also known at MIME audio/DAT12 (IETF RFC3190).

This is also known as MIME audio/L20 (IETF RFC3190)

 * Use GCC built-ins for 32-bits and 64-bits byte swap where available.
 * Load/store with single memcpy() instead of many byte operations.
 * Do not use bits operations for the local byte order.
 * Do not use reserved C keywords with leading underscores.

Note that this attribute implies that the function never returns in
any circumstances (it exits, it aborts or it gets cancelled).
Do not use this attribute for function that do not return at the end
but may return from other branches.

This can be used as follows:

 #if VLC_GCC_VERSION(major,minor)
 ...
 #endif

There is nothing "VLC" about it. The prefix is only about namespacing.
