It all started with src/extensions.c being distributed. Thanks to this, tarballs
shipped with this generated file and actually building this file was skipped.
Fix this by using the nodist_ variant of the SOURCES variable.
Due to this oversight (sorry!), the out-of-tree build wasn't actually tested.
The rule that generates src/extensions.c was missing $(srcdir) in front of the
path to extensions.py. This rule is now fixed and, as suggested by Daphne
Pfister, also changed to explicitly call the python interpreter. Configure is
changed to look for it.
Finally, extensions.c couldn't include errors.h. This worked before, because the
C compiler automatically looks for headers in the same directory as the source
file. However, for out-of-tree builds, the source directory and build directory
are different. Paper over this problem by explicitly making it look in the right
directory.

This didn't find xcb_errors.h for out-of-tree builds. Fix this by using
$(srcdir) correctly.
Also, the test suite makes use of libxcb and thus should link against it.

This is based on util-cursor's build system and libxcb/configure.ac for finding
xcb-proto's XML files.
