Adam Cozzette	501ececd39	Reorganize upb file structure 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.

Adam Cozzette	047df98dea	Move upb-x/ back to upb/ 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.	1 year ago

Joshua Haberman	a04627abc8	Added map sorting to binary and text encoders. For the binary encoder, sorting is off by default. For the text encoder, sorting is on by default. Both defaults can be explicitly overridden. This grows code size a bit. I think we could potentially shave this (and other map-related code size) by having the generated code inject a function pointer to the map-related parsing/serialization code if maps are present.
