[PATCH 13/16 v2] Extended-remote exec catchpoints

[Don Breazeal <donb@codesourcery.com>]

This patch implements exec catchpoints for extended-remote Linux targets.

The implementation follows the same appraoch used in patch 9 of this
series for fork catchpoints, implementing extended_remote target 
routines for insert/remove.  Existing host-side code and the support
for exec events introduced in patch 12 of this series takes care of
the rest.

Tested native, remote, extended-remote on x64 Ubuntu.

Thanks

	(_initialize_remote): Initialize target vector with new exec
	catchpoint functions.
