Added a more complex test case of breakpoint commands, which executes a sequence
of 'breakpoint command add/list/remove' commands to set breakpoint callbacks,
list them, and then remove one.
Modified the lldbtest.TestBase.expect() method to add two additional keyword
arguments:
o matching (default to True), which, if set to False, reverses the semantics of
'expect' to 'expect not'
o patterns (default to None), which specifies a list of regexp patterns to match
against the output from running the command
TestBreakpointCommand.py uses the matching=False and the patterns=[...] expect()
API.
