Specifically, they didn't handle installing data from both srcdir and builddir.
We have the tutorial in the srcdir, and build the manual in the builddir.
Also, stop rebuilding the manual for each make target in the doc directory, and
every time any of those targets get called. This change now makes the manual
never rebuild once built; we plan to fix that later, by rewriting the makefiles
to avoid recursive make, and then making the manual depend on the source files.

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.
Don't override the default htmldir with an unquoted copy.
Don't suppress `make` echoing on Doxygen commands.
Ensure the tutorial is always installed even if Doxygen isn't
available.
Take better advantage of the automake installation infrastructure.
