Rework doxygen build and install to work with srcdir != builddir

The documentation generation with doxygen now works when built out of tree,
with srcdir != builddir.  xcb.doxygen now gets generated from xcb.doxygen.in,
so that it can use top_builddir and top_srcdir to find source and to output
documentation.  Also fill in PROJECT_NUMBER from @VERSION@, now that we have
it readily available via autoconf.
