Add the capability of supplying the pre/post-flight functions to the test suite such that

the pre-flight code gets executed during setUp() after the debugger instance is available
and the post-flight code gets executed during tearDown() after the debugger instance has
done killing the inferior and deleting all the target programs.

Example:

[11:32:48] johnny:/Volumes/data/lldb/svn/ToT/test $ ./dotest.py -A x86_64 -v -c ../examples/test/.lldb-pre-post-flight  functionalities/watchpoint/hello_watchpoint
config: {'pre_flight': <function pre_flight at 0x1098541b8>, 'post_flight': <function post_flight at 0x109854230>}
