When using the M flags (which is functionally a mapping of
filenames to Go package paths), provide the user the ability to also
specify the package name by delimiting the package path with a ";".
Example usage:
Mpath/to/foo.proto=path/to/foo_go_proto;foopb
This uses the exact same syntax as the go_package option where a
";" delimiter can be used to specify a package name.
It brings the M flags and the go_package option closer in behavior.

In the default .pb.go filename generation mode, we generate the filename
from the import path when a file has a go_package option and the source
.proto filename otherwise.
Change filename generation when an explicit mode of paths=import is
specified to always use the import path, no matter how it was
determiend. The practical effect is that you can override the import
path of a file with Mx.proto=import/path and have this behave
identically to setting a go_package option in the file.

For historical reasons, MessageSets items are allowed to have field
numbers outside the usual valid range. Detect the case where the field
number cannot fit in an int32 and report an error. Also check for
a field number of 0 (always invalid).
Handle the case where a MessageSet item includes an unknown field.
We have no place to put the contents of the field, so drop it. This is,
I believe, consistent with other implementations.

By having the Message type implement proto.Message, it can be passed
to other general-purpose protobuf functions such as proto.Merge.
This provides a convenient way to convert the Message back into a
concrete form that may be easier to work with.
A minor consequence of this change is that invalid messages are
converted to an invalid Message that preserves type information.
Previously, they were simply transformed to a nil Message.

This test discovered that the pure protobuf reflect behavior
differs with the fast-path implementation for a few cases.
For the protobuf reflection implementation, we explicitly check
for invalid messages in Merge and Reset. Previously, these would
not panic if the message was already empty (i.e., had no need to
actually set/clear any fields in the receiver message).

The size cache is an int32. Store a -1 in it if the message size
overflows, and fall back to recomputing the size if the value is
negative. This means lamentable O(N^2) costs in marshaling,
but that's better than silently producing invalid output.
Also considered: Return an error. Avoids O(N^2) behavior, but gives the
user no good choices if they don't care the output being slow. Encoding
costs of messages this large are likely to be dominated by copying the
bytes rather than the size operation anyway, so slow-but-correct seems
like the most generally useful option.
We could store valid values for the range (0x7fffffff,0xfffffffe)
reserving only 0xffffffff as the overflow sentinel, but optimizing this
case seems less important than the code being obviously correct.
