utilize a bit reservoir. Also, make the lame encoder utilize this flag.

4bdd3b76fe mpegvideo.h has two function declarations with the 'inline' specifier 
but no definition for those functions. The C standard requires a
definition to appear in the same translation unit for any function
declared with 'inline'. Most of the files including mpegvideo.h do not
define those functions. Fix this by removing the 'inline' specifiers
from the header.
