Hi,

Some types of pending breakpoints are commonly set by using 
gdb_test_multiple to respond to the "Make breakpoint pending?" question. 
This patch adds support for several breakpoint types to gdb_breakpoint 
so that the standard machinery can be used instead.

I've also taken this opportunity to update the neglected documentation 
for gdb_breakpoint. AFAICT, "passfail" just appeared out of nowhere, and 
it has never been implemented/documented.

Comments/questions?
