a78f136f3f configure: Use a separate config_components.h header for $ALL_COMPONENTS 
This avoids unnecessary rebuilds of most source files if only the
list of enabled components has changed, but not the other properties
of the build, set in config.h.

3bf1be2101 avformat/apm: read header correctly 
The leading WAVEFORMATEX in .APM files is malformed:
* The nAvgBytesPerSec field is wrong, and
* sizeof(cbSize) is 4 instead of 2.
