Add the tools directory to the mypy pre-commit configuration.
bpf_inspect.py has a bunch of mypy errors, so we'll opt it out for now.

Now that we enable CONFIG_VIRTIO_BLK in our kconfig, there's no need to
use a loop device. Configure a virtio-blk device in vmtest.vm so that
the block helper tests have a disk to test with.

My team and I have investigated many issues that turned out to be caused
by a stray reference to a file or filesystem, either by user error or
due to a kernel bug. Userspace tools like lsof and fuser can't find all
of these. This adds a drgn-based tool similar to lsof/fuser. This
initial version only checks the basics: file descriptors, task working
directories, task root directories, task executables, and VMAs. Upcoming
changes will check additional, more obscure places.

Type units don't have a skeleton unit, so we need to walk over all of
the units in the split DWARF file to find them. Instead of doing this in
a second pass, rework drgn_dwarf_index_read_cus(): instead of
substituting skeleton units with their respective split units, call
drgn_dwarf_index_read_cus() recursively on the split DWARF file.

My elfutils patches to support .dwp files were just merged and included
in release 0.191. libdw does all of the heavy lifting, we just need to
apply the section offsets when we parse DWARF ourselves. We still need
to support older versions of elfutils, so add a stub.

Closes osandov#317.
