This turned out to be much easier for upb than for C++. This CL pretty much
just does a cut-and-paste of the `ProxiedInMapValue` implementation from the
upb code generator to the runtime. This should help a bit with code size since
it removes the need to generate six `ProxiedInMapValue` implementations per
message.

Import both the public and private header into impls when the
private is needed.
Also update the tests to use more complete imports.
PiperOrigin-RevId: 671388271
This past reliance doesn't work well with Swift, and the sources
were trying to over hand optimize to minimize rebuilds, and that
likely isn't worth the trouble, so explicit imports.
The remaining places that still use them are where they are
needed within the header to deal with relationships between
the local definitions or where there is a cycle between the
headers and it allows either one to be imported first and still
get a complete definition in the using context.

This version works where both sides are the same message, messageview or messagemut type, but not any mix of them (e.g. cannot compare a message against its corresponding view).

This also increases compliance by adding `default_applicable_licenses` to several `BUILD` files that previously did not have it.

This avoids some extra copies and garbage generation.
There's still the extra default 10-sized backing array created by default in
ProtobufArrayList which isn't fixed yet, which we see in allocation tests. That's from `ensureXIsMutable()` which allocates a new list without awareness of the list's size. Maybe we can fix that later: b/362848901.

I've tried to keep the hot part of the loop (not null) in the loop without
requiring an extra function call, and only extracted the cold part (null
handling) to avoid repetition.

The way AnyMetadata works is by holding two pointers to the fields of
google.protobuf.Any, and its methods `PackFrom` and `UnpackTo` mutates these
pointers directly.
This works but is a bit overcomplicated. A whole new object is created to
mutate members of Any directly, breaking isolation. Each Any object will also
need to unnecessarily create room to hold an AnyMetadata object, which is at
minimum the size of two pointers.
By removing AnyMetadata and using free functions, the call site passes
`const Value& foo()` and `Value* mutable_foo()` directly into `PackFrom` and
`UnpackTo`. This is more idiomatic and will play well with hasbits.
The only catch here is that in some templated implementations of `PackFrom` and
`UnpackTo`, caller will need access to T::FullMessageName(), which is in
private scope. The workaround here is to have a single templated helper
function that is made into a friend of google.protobuf.Any, so that it has the
right visibility.

These are very old unit-tests that appear to have been written to provide some conformance capabilities before we had more comprehensive solutions. Today, they should be already covered by our conformance tests and create unnecessary noise.
The goal of this change is to simply desynchronize the Java and C++ text format golden files. Java at least seems to be using these for a dual-purpose for both locking down conformance and unit-testing text format behaviors.

When the user adds `option deprecated = true` for an `enum` or `message`, we
should add the `[[deprecated]]` attribute to the generated C++ `enum` or
`class`.

The old generated code suppressed warnings broadly to support protobuf
deprecations like this showing to users, but the previous commit does
provide a debug log statement for the usages.

We need this type to be trivial and standard layout because we directly read
its contents in Rust. This change removes its user-defined constructors so that
it becomes a trivial type.

The symbol renaming support has assumed folks would define a
custom version of the macro, but if a developer does renaming
just by #defining the class, the extension singleton names
required manual handing, by changing to just wrap the class
in the macro and using the compiler string concat support
it becomes easier as just the class name remapping can do
the work for extensions.

On macOS 15, the test suite was crashing due to `pipe()` failing with `EMFILE`. On inspecting `lsof`, it appears the file descriptor table was full of duplicated `tty` file descriptors.
I'm not entirely sure what's changed in macOS 15 to tip it over the limit, but there was nevertheless clearly a file descriptor leak and this PR fixes that.
We were calling `dup(1)` and `dup(2)` to copy stdout/stderr to new temporary file descriptors, storing it `original_stdout_` and `original_stderr_`, later moving it back to FD 1 and 2 but never actually closing the temporary file descriptor.

This CL is mostly a no-op, except that now google3-only code is actually stripped from OSS, instead of being preserved in `# begin:google_only` blocks.
This follows the conventions of the greater Copybara ecosystem.

This simplifies upb by removing differences between google3 and OSS.
This also points upb at the protobuf license, instead of keeping a separate copy around for upb.

This unfortunately makes the file significantly less compact. But given that Cider will automatically perform this formatting whenever you save, this seems like a fight we are not going to win.

Fixed some shadowing between local variables
Pretty simple fix, just renaming a couple local variables so they don't shadow other variables in scope. Just trying to reduce verbosity of warnings in users' own builds with higher warning levels (as is my case ;) ).
Obviously, no change in behavior, and hopefully the new names are reasonable.

For some reason, Clang 19 appears to raise an error in some situations unless
we explicitly inline the implementation of `StrongPointer()` here.
