Added reentrant and gdb testing mechanisms to test framework

Browse Source 
Aside from reworking the internals of test_.py to work well with
inherited TestCase classes, this also provides the two main features
that were the main reason for revamping the test framework

1. ./scripts/test_.py --reentrant

   Runs reentrant tests (tests with reentrant=true in the .toml
   configuration) under gdb such that the program is killed on every
   call to lfs_emubd_prog or lfs_emubd_erase.

   Currently this just increments a number of prog/erases to skip, which
   means it doesn't necessarily check every possible branch of the test,
   but this should still provide a good coverage of power-loss tests.

2. ./scripts/test_.py --gdb

   Run the tests and if a failure is hit, drop into GDB. In theory this
   will be very useful for reproducing and debugging test failures.

   Note this can be combined with --reentrant to drop into GDB on the
   exact cycle of power-loss where the tests fail.
