I traced the issue reported by Caroline and Pavel in #134757 back to the
call to ProcessRunLock::TrySetRunning. When that fails, we get a
somewhat misleading error message:
> process resume at entry point failed: Resume request failed - process
still running.
This is incorrect: the problem was not that the process was in a running
state, but rather that the RunLock was being held by another thread
(i.e. the Statusline). TrySetRunning would return false in both cases
and the call site only accounted for the former.
Besides the odd semantics, the current implementation is inherently
race-y and I believe incorrect. If someone is holding the RunLock, the
resume call should block, rather than give up, and with the lock held,
switch the running state and report the old running state.
This patch removes ProcessRunLock::TrySetRunning and updates all callers
to use ProcessRunLock::SetRunning instead. To support that,
ProcessRunLock::SetRunning (and ProcessRunLock::SetStopped, for
consistency) now report whether the process was stopped or running
respectively. Previously, both methods returned true unconditionally.
The old code has been around pretty much pretty much forever, there's
nothing in the git history to indicate that this was done purposely to
solve a particular issue. I've tested this on both Linux and macOS and
confirmed that this solves the statusline issue.
A big thank you to Jim for reviewing my proposed solution offline and
trying to poke holes in it.

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).

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.

Summary: I was building lldb using cross mingw-w64 toolchain on Linux and observed some issues. This is first patch in the series to fix that build. It mostly corrects the case of include files and adjusts some #ifdefs from _MSC_VER to _WIN32 and vice versa. I built lldb on windows with VS after applying this patch to make sure it does not break the build there.

This diff fixes typos in file headers (incorrect file names).
Test plan:
Under llvm/tools/lldb/source:
find ./* -type f | grep -e '\(cpp\|h\)$' | while read F; do B=$(basename $F); echo $F head -n 1 $F | grep -v $B | wc -l ; done

*** 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.

This API has been present since XP, and I think it's safe to
drop support for XP (since other things have been introduced long
ago which already don't work on XP anyway).
With this patch, we can statically bind against the exports and
not bother falling back to a CRITICAL_SECTION if we can't load
the API.
