Joe Tsai 4069211bcd protogen: use full path for generated file variable name
Use the full path (including the extension) for the generation of
the per-file variable name. Several reasons for this:

* The current logic is buggy in the case where pathType == pathTypeImport
since the prefix variable will be mangled with the Go import path.

* The extension is technically part of the path.
Thus, "path/to/foo.proto" and "path/to/foo.protodevel" are two
distinctly different imports.

* Style-wise, it subjectively looks better. Rather than being a mixture
of camelCase and snake_case, it is all snake_case for the common case:
	before: ProtoFile_google_protobuf_any
	after:  File_google_protobuf_any_proto

* Since the extension is almost always ".proto", this results in a
suffix of "_proto", which provides an additional layer of protection
against possible name conflicts. The previous approach could possibly
have a conflict between "Foo.proto" and a message named ProtoFile
with a sub-message called Foo.

Also, use the per-file variable name for the raw descriptor variables
instead of the hashed version.
