Glibc calls theirs __ctype_get_mb_cur_max. Make ours match to cut down
on differences between bionic and glibc.
Bug: 11156955

Previously this was hard coded to 4. This is only the case for UTF-8
locales.
As a side effect, this properly reports C.UTF-8 as the default locale
instead of C.

Although glibc gets by with an 8-byte mbstate_t, OpenBSD uses 12 bytes (of
the 128 bytes it reserves!).
We can actually implement UTF-8 encoding/decoding with a 0-byte mbstate_t
which means we can make things work on LP32 too, as long as we accept the
limitation that the caller needs to present us with a complete sequence
before we'll process it.
Our behavior is fine when going from characters to bytes; we just
update the source wchar_t** to say how far through the input we got.
I'll come back and use the 4 bytes we do have to cope with byte sequences
split across multiple input buffers. The fact that we don't support
UTF-8 sequences longer than 4 bytes plus the fact that the first byte of
a UTF-8 sequence encodes the length means we shouldn't need the other
fields OpenBSD used (at the cost of some recomputation in cases where a
sequence is split across buffers).
This patch also makes the minimal changes necessary to setlocale(3) to
make us behave like glibc when an app requests UTF-8. (The difference
being that our "C" locale is the same as our "C.UTF-8" locale.)

pthread_once is nice for decoupling, but it makes resource availability less
predictable, which is a bad thing.
This fixes a test failure if uselocale(3) is called before
pthread.pthread_key_create_lots runs.

The OpenBSD doesn't support C99, and the extent to which we support
locales is trivial, so just do it ourselves.
