Remove a stray bit of punctuation that crept into one of the license
headers and got copied around everywhere.

The old implementation had the behavior where a nil wrapper value:
m := new(foopb.Message)
m.OneofField = (*foopb.Message_OneofUint32)(nil)
was functionally equivalent to it being directly set to nil:
m := new(foopb.Message)
m.OneofField = nil
preserve this semantic in both the table-drive implementation
and the reflection implementation.

Usage of these is pervasive in code which works with proto2, and proto2
will be with us for a long, long time to come. Move them to the proto
package.

Len looks like it should be O(1), but the need to check for
non-zero-length repeated fields makes it at minimum O(n) where n is
the number of repeated fields. In practice, it's O(n) where n is the
number of fields altogether.
The Len function is not especially useful, easily duplicated with Range
and a counter, and can be surprisingly inefficient. Drop it.

Fix a bug where using Message.Range alone does not clear
memory references for empty, but allocated lists and maps.
Thus, we iterate over every known field and explicitly call Clear.
