Currently, if the user doesn't specify a vmlinux image or an
autodumpdir (like when running ramparse.py with absolutely no arguments)
they get a big ugly python stacktrace and no helpful error message. Fix
this.

Currently we error out and ask the user to create the output directory
if it doesn't exist. As a convenience, just create the directory for
them.

It's not uncommon for the vmlinux file to live in the same directory as
the actual RAM dumps. If the users doesn't explicitly specify a vmlinux
image to use, look for it in the autodump dir. If we still can't find it
there, error out as usual.

When local_settings.py is missing variables we just error out when
trying to access those attributes. Improve the error message by
mentioning local_settings.py and pointing the user to README.txt.

During development, it's quite convenient to load up an interactive
python interpreter with a RamDump instance loaded. Add some command line
switches to launch an interactive shell with the RamDump instance that
gets created as a result of whatever other command line options are
passed.

If IPython is installed, an IPython interpreter will be launched,
otherwise a classic Python interpreter will be launched. The classic
interface can also be forced with --classic-shell.

Ram dumps are now being generated for 64-bit ramdumps. Update the
parser to account for this.

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.

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.
