[pushed][PATCH v3 2/4] Extended-remote exec catchpoints

Here is what I pushed.

This patch implements exec catchpoints for extended-remote Linux
targets.  The implementation follows the same approach used for
fork catchpoints, implementing extended-remote target routines for
inserting and removing the catchpoints by just checking if exec events
are supported.  Existing host-side code and previous support for
extended-remote exec events takes care of the rest.

Tested on x86_64 GNU/Linux with native, native-gdbserver, and
native-extended-gdbserver targets.
