[lldb] Add setting to override PE/COFF ABI by module name

The setting `plugin.object-file.pe-coff.module-abi` is a string-to-enum
map that allows specifying an ABI to a module name. For example:

[lldb] Add setting to override PE/COFF ABI by module name

The setting `plugin.object-file.pe-coff.module-abi` is a string-to-enum
map that allows specifying an ABI to a module name. For example:

ucrtbase.dll=msvc
libstdc++-6.dll=gnu

This allows for debugging a process which mixes both modules built using
the MSVC ABI and modules built using the MinGW ABI.

[lldb/Interpreter][NFC] Remove explicit default initialization of members and base classes

According to clang-tidy's readability-redundant-member-init.

Add an option (-y) to "break set" and "source list" that uses the same
file:line:column form that we use to print out locations. Since we
print them this way it makes sense we also accept that form.

[lldb][NFC] Fix all formatting errors in .cpp file headers

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).

This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Pass ConstString by value (NFC)

My apologies for the large patch. With the exception of ConstString.h
itself it was entirely produced by sed.

ConstString has exactly one const char * data member, so passing a
ConstString by reference is not any more efficient than copying it by
value. In both cases a single pointer is passed. But passing it by
value makes it harder to accidentally return the address of a local
object.

Update the file headers across all of the LLVM projects in the monorepo
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.

Add functionality to export settings

For the reproducer feature I need to be able to export and import the
current LLDB configuration. To realize this I've extended the existing
functionality to print settings. With the help of a new formatting
option, we can now write the settings and their values to a file
structured as regular commands.

Concretely the functionality works as follows:

(lldb) settings export -f /path/to/file

This file contains a bunch of settings set commands, followed by the
setting's name and value.

...
settings set use-external-editor false
settings set use-color true
settings set auto-one-line-summaries true
settings set auto-indent true
...

You can import the settings again by either sourcing the file or using
the settings read command.

(lldb) settings read -f /path/to/file

Don't allow direct access to StreamString's internal buffer.

This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.

Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

Fix more functions in Args to use StringRef.

This patch also marks the const char* versions as =delete to prevent
their use. This has the potential to cause build breakages on some
platforms which I can't compile. I have tested on Windows, Linux,
and OSX. Best practices for fixing broken callsites are outlined in
Args.h in a comment above the deleted function declarations.

Eventually we can remove these =delete declarations, but for now they
are important to make sure that all implicit conversions from
const char * are manually audited to make sure that they do not invoke a
conversion from nullptr.

*** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

None of the files that were including this header actually depended
