Split all non-essential extensions into their own separate libraries, named

libXCBextname.  To use extension extname, include extname.h and link with
-lXCBextname.  This allows extensions to change without bumping the main
libXCB version.

bigreq and xc_misc remain in libXCB, because XCB uses them internally to make
big requests and to allocate XIDs, respectively.
