A recent build has generated multiple badly corrupted dumps. Fix
all the errors found by the unintentional fuzzing.

Red/Black trees are supposed to be trees, not directed cyclic graphs.
Sometimes trees in ramdumps may become corrupted though, resulting in
cycles. Detect these cycles in the tree to avoid looping forever.

Workqueues may be modified at runtime which can leave them in an
inconsistent state in ram dumps. Check for infinite loops in
workqueue lists caused by this state.

Somewhere along the way we started ignoring the --nm-path and --gdb-path
options. Fix this. Also ensure that the command line options take
precedence over anything from local_settings.py or anything discovered
from CROSS_COMPILE.

We are currently printing gdb_path when there are issues with
nm_path. Fix this by printing nm_path. Also change local_settings.pyi to
local_settings.py.

Sometimes the slabinfo data structures may be corrupt because of software
error or when the ramdumps were collected. Detect this bettter to
avoid looping forever or going out of bounds.

Older targets use a slightly different version of map around the hole
which has different variable names. Account for this in the code.

Several imports were dropped during code refactor. Re-add them.

The alternate workqueue function is based on 3.0, not 3.4. Fix the
name.

After a crash, ramdumps may be collected for analysis. The ram
parser is a tool to aid in analysis of these dumps. The script
extracts useful information from the dumps to help with debugging.
Please see the README for full details.
