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.

The *real* difference between these two was that
a) The "graphical" dumper could recurse, while the text one could
not.
b) The "text" dumper could display nested types and functions,
while the graphical one could not.
Merge these two so that there is only one dumper that can recurse
arbitrarily deep and optionally display nested types or not.

This reworks the way virtual bases are handled, and also the way
padding is detected across multiple levels of aggregates, producing
a much more accurate result.

Previously the dumping of class definitions was very primitive,
and it made it hard to do more than the most trivial of output
formats when dumping. As such, we would only dump one line for
each field, and then dump non-layout items like nested types
and enums.
With this patch, we do a complete analysis of the object
hierarchy including aggregate types, bases, virtual bases,
vftable analysis, etc. The only immediately visible effects
of this are that a) we can now dump a line for the vfptr where
before we would treat that as padding, and b) we now don't
treat virtual bases that come at the end of a class as padding
since we have a more detailed analysis of the class's storage
usage.
In subsequent patches, we should be able to use this analysis
to display a complete graphical view of a class's layout including
recursing arbitrarily deep into an object's base class / aggregate
member hierarchy.

When dumping classes, show where padding occurs, and at the end of the
class print statistics about how many bytes total of padding exist in a
class.
Since PDB doesn't specifically contain information about padding, we have
to mimic this by sort of reversing a small portion of the record layout
algorithm (e.g. looking at offsets and sizes and trying to determine
whether something is part of the same field or a new field).

Previously when dumping class definitions, there were only
two modes - on or off. But it's useful to sometimes get a
little more fine-grained. For example, you might only want
to see the record layout (for example to look for extraneous
padding). This patch adds a third mode, layout mode, which
does exactly that. Only this-relative data members are
displayed in this mode.

Summary:
There are a number of files in the tree which have been accidentally checked in with DOS line endings. Convert these to native line endings.
There are also a few files which have DOS line endings on purpose, and I have set the svn:eol-style property to 'CRLF' on those.

A short list of some of the improvements:
1) Now supports -all command line argument, which implies many
other command line arguments to simplify usage.
2) Now supports -no-compiler-generated command line argument to
exclude compiler generated types.
3) Prints base class list.
4) -class-definitions implies -types.
5) Proper display of bitfields.
6) Can now distinguish between struct/class/interface/union.
And a few other minor tweaks.
