mtrace: Deprecate mallwatch and tr_break
The variable and function pair appear to provide a way for users to
set conditional breakpoints in mtrace when a specific address is
returned by the allocator. This can be achieved by using conditional
breakpoints in gdb so it is redundant. There is no documentation of
this interface in the manual either, so it appears to have been a hack
that got added to debug malloc. Deprecate these symbols and do not
call tr_break anymore.
