[RFA] lengthen timeouts in gdb.base/checkpoint.exp

[dje@google.com (Doug Evans)]

Hi.

I'm seeing timeout failures in gdb.base/checkpoint.exp
on the 7.1 branch.

Running ../../../../src/gdb/testsuite/gdb.base/checkpoint.exp ...
FAIL: gdb.base/checkpoint.exp: break2 with many checkpoints (timeout)
FAIL: gdb.base/checkpoint.exp: info checkpoints with at least 600 checkpoints (timeout)
FAIL: gdb.base/checkpoint.exp: kill all one (timeout)

Ok to apply to trunk and 7.1 branch?

I went with adding a number to the existing timeout value because
I didn't want to make any assumptions on what the existing timeout
value was (I can imagine wanting to globally increase the timeout
to some value when testing a slow serial target).
I cut-n-pasted the means to save/restore timeout from watchpoint.exp.

	* gdb.base/checkpoint.exp: Fix comment.
	Lengthen timeout while doing >600 checkpoints test.
	Rename duplicate "kill all one" test to keep test names unique.
