>Description:
Remove sideffects from libgdb breakpoint create function.

The user can use the CLI to create a breakpoint with partial
information - no file (gdb would use the file from the last
breakpoint).

The libgdb interface currently affects that environment which can lead
to confusion when a user is setting breakpoints via both the MI and
the CLI.

This is also a good example of how getting the CLI ``right'' will be
hard.
