Previously this change was submitted from a Windows machine, so
changes made to the case of filenames and directory names did
not survive the commit, and as a result the CMake source file
names and the on-disk file names did not match on case-sensitive
file systems.
I'm resubmitting this patch from a Linux system, which hopefully
allows the case changes to make it through unfettered.

In a previous patch, it was suggested to use all caps instead of
rolling caps for initialisms, so this patch changes everything
to do this.

This makes it easier to have the writable and readable PDB
interfaces share code since the read/write and write-only
interfaces now share a single allocator, you don't have to worry
about a builder building a read only interface and then having
the read-only interface's data become corrupt when the builder
goes out of scope. Now the allocator is specified explicitly
to all constructors, so all interfaces can share a single allocator
that is scoped appropriately.

This provides a better layering of responsibilities among different
aspects of PDB writing code. Some of the MSF related code was
contained in CodeView, and some was in PDB prior to this. Further,
we were often saying PDB when we meant MSF, and the two are
actually independent of each other since in theory you can have
other types of data besides PDB data in an MSF. So, this patch
separates the MSF specific code into its own library, with no
dependencies on anything else, and DebugInfoCodeView and
DebugInfoPDB take dependencies on DebugInfoMsf.

This is the next step towards being able to write PDBs.
MemoryBuffer is immutable, and StreamInterface is our replacement
which can be any combination of read-only, read-write, or write-only
depending on the particular implementation.
The one place where we were creating a PDBFile (in RawSession) is
updated to subclass ByteStream with a simple adapter that holds
a MemoryBuffer, and initializes the superclass with the buffer's
array, so that all the functionality of ByteStream works
transparently.

r267049 broke multiple buildbots (e.g. clang-cmake-mips, and clang-x86_64-linux-selfhost-modules) which the follow-ups have not yet resolved and this is preventing subsequent committers from being notified about additional failures on the affected buildbots.

PDB parsing code was hand-rolled into llvm-pdbdump. This patch moves the
parsing of this code into DebugInfoPDB and makes the dumper use this.
This is achieved by implementing the skeleton of RawPdbSession, the
non-DIA counterpart to the existing PDB read interface. None of the type /
source file / etc information is accessible yet, so this implementation is
not yet close to achieving parity with the DIA counterpart, but the
RawSession class simply holds a reference to a PDBFile class which handles
parsing the file format. Additionally a PDBStream class is introduced
which allows accessing the bytes of a particular stream in a PDB file.
