This should significantly reduce the size of large arenas. Previously, a large arena would nearly double in size if the most recent block filled up. This could end up wasting large amounts of memory. After this CL, we will waste at most the max block size, which defaults to 32k.
This more or less matches the behavior of the C++ arena.

This change moves almost everything in the `upb/` directory up one level, so
that for example `upb/upb/generated_code_support.h` becomes just
`upb/generated_code_support.h`. The only exceptions I made to this were that I
left `upb/cmake` and `upb/BUILD` where they are, mostly because that avoids
conflict with other files and the current locations seem reasonable for now.
The `python/` directory is a little bit of a challenge because we had to merge
the existing directory there with `upb/python/`. I made `upb/python/BUILD` into
the BUILD file for the merged directory, and it effectively loads the contents
of the other BUILD file via `python/build_targets.bzl`, but I plan to clean
this up soon.

A couple weeks ago we moved upb into the protobuf Git repo, and this change
continues the merger of the two repos by making them into a single Bazel repo.
This was mostly a matter of deleting upb's WORKSPACE file and fixing up a bunch
of references to reflect the new structure.
Most of the changes are pretty mechanical, but one thing that needed more
invasive changes was the Python script for generating CMakeLists.txt,
make_cmakelists.py. The WORKSPACE file it relied on no longer exists with this
change, so I updated it to hardcode the information it needed from that file.

This is the second attempt to fix our Git history. This should allow
"git blame" to work correctly in the upb/ directory even though our
automation unexpectedly blew away that directory.
Clang and GCC differ on how they detect Address Sanitizer. Support both.
Closes#1424

This will move us towards keeping all these encapsulation breaks in a common place.
This also removes the IFTTT blocks. Keeping IFTTT blocks for each language would become unmanageable, but going forward we will know to look in `//third_party/upb/bits` whenever the internal data structures in upb change.

It no longer has any users. If we need it later, we can add it back.
This saves one pointer of memory from `sizeof(upb_Arena)`.
Also, we now allow fuses if if the block allocators differ. This is made possible by cl/520144430, but was not take advantage of in that CL.

_upb_Arena_FastMalloc() has been directly inlined
Arena::allocator() has been removed
mem_block is now _upb_MemBlock
some calls to upb_Arena_Alloc() (which is going away) have been changed to use upb_Arena_Malloc() instead

Ref: https://github.com/protocolbuffers/protobuf/pull/10291
Ruby types defined though native extensions should register
a function that report their memory footprint in bytes.
This feature is used by various memory profiling tools.
some headers were not including port_def.inc
some headers were not declaring extern "C"
some headers were backing out of the above in the wrong order

Lots of changes but it's all just moving things around.
Backward-compatible stub #include's have been provided for now.
upb_Arena/upb_Status have been split out from upb/upb.?
upb_Array/upb_Map/upb_MessageValue have been split out from upb/collections.?
upb_ExtensionRegistry has been split out from upb/msg.?
upb/decode_internal.h is now upb/internal/decode.h
upb/mini_table_accessors_internal.h is now upb/internal/mini_table_accessors.h
upb/table_internal.h is now upb/internal/table.h
upb/upb_internal.h is now upb/internal/upb.h

An enum MiniDescriptor simply encodes a set of valid `int32_t` values, so that the protobuf parser can test whether a given enum value is known or not.
The format implemented here is novel and needs to be documented. In short, the format is:
1. base92 values 0-31: 5-bit mask indicating presence or absence of the next five enum values.
2. base92 values 60-91: varint indicating skip over a region of enum values.
Negative enum values are encoded as their `uint32_t` equivalent.
