This resubmits commit c0c249e9f2ef83e1d1e5f166b50673d92f3579d7.
It was broken due to some weird template issues, which have
since been fixed.

This reverts commit 83ea17ebf2106859a51fbc2a86031b44d33696ad.
This is failing due to some strange template problems, so reverting
until it can be straightened out.

After some internal discussions, we agreed that the raw output style had
outlived its usefulness. It was originally created before we had even
thought of dumping to YAML, and it was intended to give us some insight
into the internals of a PDB file. Now we have YAML mode which does
almost exactly this but is more powerful in that it can round-trip back
to a PDB, which the raw mode could not do. So the raw mode had become
purely a maintenance burden.
One option was to just delete it. However, its original goal was to be
as readable as possible while staying close to the "metal" - i.e.
presenting the output in a way that maps directly to the underlying file
format. We don't actually need that last requirement anymore since it's
covered by the yaml mode, so we could repurpose "raw" mode to actually
just be as readable as possible.
This patch implements about 80% of the functionality previously in raw
mode, but in a completely different style that is more akin to what
cvdump outputs. Records are very compressed, often times appearing on
just one line. One nice thing about this is that it makes full record
matching easier, because you can grep for indices, names, and leaf types
on a single line often.
See the tests for some examples of what the new output looks like.
Note that this patch actually regresses the functionality of raw mode in
a few areas, but only because the patch was already unreasonably large
and going 100% would have been even worse. Specifically, this patch is
missing:
The ability to dump module debug subsections (checksums, lines, etc)
The ability to dump section headers
Aside from that everything is here. While goign through the tests fixing
them all up, I found many duplicate tests. They've been deleted. In
subsequent patches I will go through and re-add the missing
functionality.

This is to reflect the evolving nature of the tool as being
useful for more than just dumping PDBs, as it can do many other
things.

This adds support for Symbols, StringTable, and FrameData subsection
types. Even though these subsections rarely if ever appear in a PDB
file (they are usually in object files), there's no theoretical reason
why they *couldn't* appear in a PDB. The real issue though is that in
order to add support for dumping and writing them (which will be useful
for object files), we need a way to test them. And since there is no
support for reading and writing them to / from object files yet, making
PDB support them is the best way to both add support for the underlying
format and add support for tests at the same time. Later, when we go
to add support for reading / writing them from object files, we'll need
only minimal changes in the underlying read/write code.

This is the same change for the YAML Output style applied to the
raw output style. Previously we would queue up all subsections
until every one had been read, and then output them in a pre-
determined order. This was because some subsections need to be
read first in order to properly dump later subsections. This
patch allows them to be dumped in the order they appear.

The pdb2yaml and raw subcommands did something very
similar but with a different output format, and they
used a lot of the same command line options, but each
one re-implemented the command line option with slightly
different spellings / options. This patch merges them
together into a single definition which is shared by
both subcommands. This new syntax also allows for more
flexibility in the way debug subsections are dumped.
