to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This will show more detail when using `llvm-pdbutil explain` on an
offset in the DBI or PDB streams. Specifically, it will dig into
individual header fields and substreams to give a more precise
description of what the byte represents.

This adds support for dumping a summary of module symbols
and CodeView debug chunks. This option prints a table for
each module of all of the symbols that occurred in the module
and the number of times it occurred and total byte size. Then
at the end it prints the totals for the entire file.
Additionally, this patch adds the -jmc (just my code) option,
which suppresses modules which are from external libraries or
linker imports, so that you can focus only on the object files
and libraries that originate from your own source code.

This was originally reverted because of two issues.
1) Printing ANSI color escape codes even when outputting to
a file
2) Module name comparisons were failing when comparing a PDB
generated on one machine to a PDB generated on another
machine.
I attempted to fix#2 by adding command line options which let
you specify prefixes to strip from the beginning of embedded
paths, which effectively lets us specify a path to "base" each
PDB from and only compare the parts under the base. But this is
tricky because PDB paths always use Windows path syntax, even
when they are created on non-Windows hosts. A problem still
existed when constructing the prefix to strip, where we were
accidentally using a host-specific path separator instead of
a Windows path separator.
This resubmission fixes the issue on Linux (and I have verified
that the test now passes on Linux).

A test was checked in on Friday that worked by checking in an
object file and PDB generated locally by MSVC, and then having
the test run lld-link on the object file and diffing LLD's PDB
against the checked in PDB.
This failed because part of the diffing algorithm involves
determining if two modules are the same, and if so drilling into
the module and diffing individual fields of the module. The
only thing we can use to make this determination though is the
"name" of the module, which is a path to where the module (obj
file) was read from on the machine where it was linked. This
fails for obvious reasons when comparing a PDB generated on one
machine to a PDB on another machine.
The fix employed here is to add two command line options to the
diff subcommand, which allow the user to specify a "binary root
path". The bin root path, if specified, is stripped from the
beginning of any embedded PDB paths. The test is updated to
specify the user's local test output directory for the left
PDB, and is hardcoded to the location where the original PDB
was created for the right PDB. This way all the equivalence
comparisons should succeed.

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.
