changes.
(1) Use PROTOBUF_NOINLINE attributes to avoid inlining of
Clear(), ByteSizeLong() and IsInitialized() routines
within the same .pb.cc file
(2) If the tag number is less than 16 and the type is one of
a handful of common types, call a non-inlined templated
routine specialized for that tag number that handles both
the EnsureSpace call and the encoding of the tag and the
value into the array.

Without it some compilers will not constant initialize the tables and cause
runtime failures during registration. We must be able to parse descriptors
during dynamic initialization.

We found last week that Clang's support for `musttail` on 32-bit Linux does not
seem to work reliably, so let's disable it for now.

While embedded nulls are technically allowed in JSON strings (and thus as object keys), they put undesirable constraints on implementations. Embedded nulls require that string length is stored explicitly, which wastes memory to accommodate a case that virtually nobody wants or needs.

This is a new feature allowing fields to be annotated with a `targets` option
specifying what kinds of entities that field may be applied to when used in an
option.

Sanitizers are picky for container start addresses to be aligned at 8 byte aligned offsets, which causes issues under 32 bit compilations as we lay out the internal layout as {arena*, elements[...]}. This change forces the minimum header size to be at least 8 bytes, adding padding as needed.

These changes hid public APIs that are deprecated in advance of protobuf editions. They will be fully removed in a future release. Any uses of them should be migrated to the future-facing feature helpers we provide on descriptor classes.

This way, when e.g. `Arena::CreateMessage<RepeatedPtrField<Msg>>` is called with a non-null arena, we won't end up calling the destructor of the repeated field later.
Also add some missing includes in unittest.

This saves 24 bytes on each `map` field when reflection is not used.
It also delays constructing a Mutex until reflection is needed. This means we do
not have to register the mutex for destruction in the arena for normal
operation.
