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.

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.
If a proto_library has more than one srcs, we designate the first one as the primary (that file will be passed to rustc as the crate root). All other files will represent (internal) submodules of the crate.
In general, Rust users won't see which .proto file a message came from, they will only see a crate corresponding to the entire proto_library, and in it public submodules for all `package` statements in all .proto files in the proto_library sources. Therefore in this CL we reexport all messages from non primary sources into their corresponding public modules (= packages declared in their owning .proto files).
Besides the common case this CL also handles .proto files without package statement, and a subset of behaviors needed for public import functionality.

This CL introduces two new files, names.h and context.h.
The former is intended to hold functions that generate the stringified names of things to splat into text templates. The latter holds per-invocation options, and a Context struct that makes it easy to thread extra information throughout the codegen backend.

After this change, the Rust codegen can be enabled via the protoc flag '--rust_out'. Due to its experimental nature we require a magic value to be provided '--rust_out=experimental-codegen=enabled:<out>'.
Make the 'RustGenerator' create an empty *.pb.rs file.

This code is experimental and should not be expected to emit working code, and callers are liable to break without warning.
It is being released now so that development can occur in the open, but users should not expect this to be supported any time soon.

* WIP.
* WIP.
* Builds and runs. Tests need to be updated to test presence.
* Ruby: proto3 presence is passing all tests.
* Fixed a bug where empty messages has the wrong oneof count.
* Some fixes to make the code work in google3.
* Removed plugin.h.
* Some more fixes to be namespace-independent.
* More fixes for namespace independence.
* A few final fixes.
* Another fix (hide ToUpper from Copybara).
* Fix for charp_unittest.
This adds a Ruby extension in ruby/ that is based on the 'upb' library
(now included as a submodule), and adds support for Ruby code generation
to the protoc compiler.
General
* License changed from Apache 2.0 to New BSD.
* It is now possible to define custom "options", which are basically
annotations which may be placed on definitions in a .proto file.
For example, you might define a field option called "foo" like so:
import "google/protobuf/descriptor.proto"
extend google.protobuf.FieldOptions {
optional string foo = 12345;
}
Then you annotate a field using the "foo" option:
message MyMessage {
optional int32 some_field = 1 [(foo) = "bar"]
}
The value of this option is then visible via the message's
Descriptor:
const FieldDescriptor* field =
MyMessage::descriptor()->FindFieldByName("some_field");
assert(field->options().GetExtension(foo) == "bar");
This feature has been implemented and tested in C++ and Java.
Other languages may or may not need to do extra work to support
custom options, depending on how they construct descriptors.
C++
* Fixed some GCC warnings that only occur when using -pedantic.
* Improved static initialization code, making ordering more
predictable among other things.
* TextFormat will no longer accept messages which contain multiple
instances of a singular field. Previously, the latter instance
would overwrite the former.
* Now works on systems that don't have hash_map.
Python
* Strings now use the "unicode" type rather than the "str" type.
String fields may still be assigned ASCII "str" values; they will
automatically be converted.
* Adding a property to an object representing a repeated field now
raises an exception. For example:
# No longer works (and never should have).
message.some_repeated_field.foo = 1
