Before this CL we only used features where they were applicable, e.g.
file features were only set on the file descriptor and field features
only on the fields descriptor. After this CL all descriptors (file,
message and field) contain always all features and when initializing
either of them we merge the features specified by options with the
features of the parent descriptor and use the result as the effective
feature. This way we initialize all the descriptors the same way and the
proto spec can change on which level features can be specified without
us having to change the code (at the moment most features can only be
specified on file or field level, in the future message might also be
possible).

This fixes a bug introduced by CL/182360.
Overview of the problem:
* CL/182360 removes the internal/prototype package, such that
protodesc was re-implemented using internal/filedesc.
* As a result of that change, resolving internal dependencies became
the responsibility of protodesc.
* Dependency resolution used the following two-pass algorithm:
1) first pass derives the full name of all declarations
2) second pass fully initializes each descriptor declaration,
now being able to resolve local dependencies from the previous step.
* When the second pass looks up a local dependency, it is guaranteed to
find it, but it is not guaranteed that the dependency has been initialized
(since it may appear later on). This is problematic for default enum values
since it implies that the enum dependency may not be sufficiently
initialized to be able to query its set of values, leading to panics.
* CL/182360 recognized the problem and attempted to enforce an initialization
ordering where nested enums were always initialized before the body of the
message declaration itself.
* However, that ordering fails to enforce that that enum declarations outside
the parent tree are initialized beforehand. For example, referring to an
enum value that is declared within a sibling of the parent message.
* This CL fixes the problem with a three-pass algorithm:
1) first pass derives the full name *and* fully initialize the
entire descriptor *except* for dependency references (i.e., type_name).
2) second pass only resolves dependency references,
where we do not need to worry about initialization ordering.
3) third pass validates the descriptors are well-formed.
This can now depend on all information being fully initialized.
* While a lot of code moves, this change is actually very mechanical.
Other than split things apart, no new logic is introduced nor removed.

This change makes it such that Files now functionally registers all
descriptors in a file (not just enums, messages, extensions, and services),
but also including enum values, messages fields/oneofs, and service methods.
The ability to look up any descriptor by full name is needed to:
1) properly detect namespace conflicts on enum values
2) properly implement the relative name lookup logic in reflect/protodesc
The approach taken:
1) Assumes that a FileDescriptor has no internal name conflicts.
This will (in a future CL) be guaranteed by reflect/protodesc and
is guaranteed today by protoc for generated descriptors.
2) Observes that the only declarations that can possibly conflict
with another file are top-level declarations (i.e., enums, enum values,
messages, extensions, and services). Enum values are annoying
since they live in the same scope as the parent enum, rather than
being under the enum.
For the internal data structure of Files, we only register the top-level
declarations. This is the bare minimum needed to detect whether the file
being registered has any namespace conflicts with previously registered files.
We shift the effort to lookups, where we now need to peel off the end fragments
of a full name until we find a match in the internal registry. If a match
is found, we may need to descend into that declaration to find a nested
declaration by name.
For initialization, we modify internal/filedesc to initialize the
enum values for all top-level enums. This performance cost is offsetted
by the fact that Files.Register now avoids internally registering
nested enums, messages, and extensions.
For lookup, the cost has shifted from O(1) to O(N),
where N is the number of segments in the full name.
Top-level descriptors still have O(1) lookup times.
Nested descriptors have O(M) lookup times,
where M is the level of nesting within a single file.

Previously, we liberally permitted mutiple files to be registered that
have the same path. However, doing so causes complexity in various places
that need to assume that file paths are unique. Since unique paths are
the intention of the proto language, we strictly enforce that now.

Rename each generated protobuf package such that the base of the
Go package path is always equal to the Go package name to follow
proper Go package naming conventions.
The Go package name is derived from the .proto source file name by
replacing ".proto" with "pb" and stripping all underscores.
