Committed the basic builtin provider, supporting only the "C" locale.

There were a few changes since the last version I posted:

* Added simplistic validation of the locale name to initdb.c (missing
before).
* Consistently passed the locale name to
get_collation_actual_version(). In the previous patch, the caller
sometimes just passed NULL knowing that the builtin provider is not
versioned, but that's not the caller's responsibility.
* pg_dump previously had some minor refactoring, which you had some
questions about. I eliminated that and just kept it to the changes
necessary for the builtin provider.
* createdb --help was missing the --builtin-locale option
* improved error checking order in createdb() to avoid a confusing
error message.

I also attached a rebased series.

0001 (the C.UTF-8 locale) is also close. Considering that most of the
infrastructure is already in place, that's not a large patch. You many
have some comments about the way I'm canonicalizing and validating in
initdb -- that could be cleaner, but it feels like I should refactor
the surrounding code separately first.

0002 (inlining utf8 functions) is also ready.

For 0003 and beyond, I'd like some validation that it's what you had in
mind.
