Get rid of upb_symtabtxn.
...
This type was nothing but a map of defs.
We can as easily just pass an array of defs
into upb_symtab_add().

Directory restructure.
...
Includes are now via upb/foo.h.
Files specific to the protobuf format are
now in upb/pb (the core library is concerned
with message definitions, handlers, and
byte streams, but knows nothing about any
particular serializationf format).

Update copyright to be Google Inc.
...
This doesn't reflect any material change in
how I will be working on upb, and I have no
problem making this change. It's still open
source under the BSD license, and I'll still
be working on it well beyond the hours that
constitute a normal job.

First version of an assembly language decoder.
...
It is slower than the C decoder for now because it
falls off the fast path too often. But it can
successfully decode varints, fixed32 and fixed64.

Split inttable into a hash part and an array part.
...
upb_inttable() now supports a "compact" operation that will
decide on an array size and put all entries with small enough
keys into the array part for faster lookup.
Also exposed the upb_itof_ent structure and put a few useful
values there, so they are one fewer pointer chase away.

Recover bad performance of 0-keyed tables.
...
We do this by special-casing the (unusual) zero case
and only bother checking the is_empty bit in the
zero case.

More completely fixed the 0-key thing.
...
Unfortunately this degrades hash table lookup performance by
about 8%, which affects the streaming benchmark for googlemessage1
by about 5%. We could get this back at the cost of some memory,
but it would be nice to avoid that.
