Make SearchMatch an interface, exclude 'context', move implementation.

Make SearchMatch an interface, exclude 'context', move implementation.


Also, mostly drop 'fileStamp' in SourceFileEdit.
Only `-1` is kept when the file is a new one, in other cases it' `0`.
As I can see, IDEA cares only about `-1`.
We don't know modification stamps with the new analysis driver.
But we know content hashes.

Do we know what the effect will be on other clients?

Other than that, lgtm.

File pkg/analysis_server/lib/src/protocol_server.dart (right):

https://codereview.chromium.org/2518903002/diff/1/pkg/analysis_server/lib/src...
pkg/analysis_server/lib/src/protocol_server.dart:55: * Adds [edit] to the file
with the [element] for the given [element].
This seems redundant. Perhaps "to the file containing the given"?
