[lldb] Rename Logging.h to LLDBLog.h and clean up includes

Most of our code was including Log.h even though that is not where the
"lldb" log channel is defined (Log.h defines the generic logging
infrastructure). This worked because Log.h included Logging.h, even
though it should.

After the recent refactor, it became impossible the two files include
each other in this direction (the opposite inclusion is needed), so this
patch removes the workaround that was put in place and cleans up all
files to include the right thing. It also renames the file to LLDBLog to
better reflect its purpose.

[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).

Replace 'ap' with 'up' suffix in variable names. (NFC)

The `ap` suffix is a remnant of lldb's former use of auto pointers,
before they got deprecated. Although all their uses were replaced by
unique pointers, some variables still carried the suffix.

In r353795 I removed another auto_ptr remnant, namely redundant calls to
::get for unique_pointers. Jim justly noted that this is a good
opportunity to clean up the variable names as well.

I went over all the changes to ensure my find-and-replace didn't have
any undesired side-effects. I hope I didn't miss any, but if you end up
at this commit doing a git blame on a weirdly named variable, please
know that the change was unintentional.

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.

[windows] LLDB shows the wrong values when register read is executed at a frame other than zero

Summary:
This is a clean version of the change suggested here: https://bugs.llvm.org/show_bug.cgi?id=37495

The main change is to follow the same pattern as non-windows targets and use an unwinder object to retrieve the register context. I also changed a couple of the comments to actually log, so that issues with unsupported scenarios can be tracked down more easily. Lastly, ClearStackFrames is implemented in the base class, so individual thread implementations don't have to override it.

[Windows, Process] Fix an issue in windows thread handling that was causing LLDB to hang

Summary: The function ResumeThread on Windows returns a DWORD which is an unsigned int. In TargetThreadWindows::DoResume, there's code that determines how many times to call ResumeThread based on whether the return value is greater than 0. Since the function returns -1 (as an unsigned int) on failure, this was getting stuck in an infinite loop if ResumeThread failed for any reason. The correct thing to do is check whether the return value is -1 and then return the appropriate error instead of ignoring the return value.

Refactor LLDB's Windows process plugin (NFC)

The Windows process plugin was broken up into multiple pieces a while back in
order to share code between debugging live processes and minidumps
(postmortem) debugging. The minidump portion was replaced by a cross-platform
solution. This left the plugin split into a formerly "common" base classes and
the derived classes for live debugging. This extra layer made the code harder
to understand and work with.

This patch simplifies these class hierarchies by rolling the live debugging
concrete classes up to the base classes. Last week I posted my intent to make
this change to lldb-dev, and I didn't hear any objections.

This involved moving code and changing references to classes like
ProcessWindowsLive to ProcessWindows. It still builds for both 32- and 64-bit,
and the tests still pass on 32-bit. (Tests on 64-bit weren't passing before
this refactor for unrelated reasons.)
