wm4 4873b32c59 Rename directories, move files (step 2 of 2) 
Finish renaming directories and moving files. Adjust all include
statements to make the previous commit compile.

The two commits are separate, because git is bad at tracking renames
and content changes at the same time.

Also take this as an opportunity to remove the separation between
"common" and "mplayer" sources in the Makefile. ("common" used to be
shared between mplayer and mencoder.)

/*
* *BSD (hopefully, requires working driver!) BrookTree capture support.
*
* Still in (active) development!
*
* v1.1 Mar 13 2002 Fully functional, need to move ring buffer to
* the kernel driver.
* v1.0 Feb 19 2002 First Release, need to add support for changing
* audio parameters.
