Use LLDB_PLUGIN_DEFINE_ADV to make the name of the generated initializer
match the name of the plugin. This is a step towards generating the
initializers with a def file. I'm landing this change in pieces so I can
narrow down what exactly breaks the Windows bot.
This patch changes the way we initialize and terminate the plugins in
the system initializer. It uses an approach similar to LLVM's
TARGETS_TO_BUILD with a def file that enumerates the plugins.
The previously landed patch got reverted because it was lacking:
(1) A plugin definition for the Objective-C language runtime,
(2) The dependency between the Static and WASM dynamic loader,
(3) Explicit initialization of ScriptInterpreterNone for lldb-test.
All issues have been addressed in this patch.

This is a step towards making the initialize and terminate calls be
generated by CMake, which in turn is towards making it possible to
disable plugins at configuration time.

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).

This can e.g. happen if the debugged executable exits before the initial
stop, e.g. if it fails to load dependent DLLs.
Add a virtual destructor to ProcessDebugger and let it clean up the
session, and make ProcessWindows::OnExitProcess call
ProcessDebugger::OnExitProcess for shared parts.

Summary:
This patch introduces a switch, based on the environment variable
`LLDB_USE_LLDB_SERVER`, to determine whether to use the `ProcessWindows` plugin
(the old way) or the `lldb-server` way for debugging on Windows.

Summary:
This patch adds support of watchpoints to the old `ProcessWindows` plugin.
The `ProcessWindows` plugin uses the `RegisterContext` to set and reset
watchpoints. The `RegisterContext` has some interface to access watchpoints,
but it is very limited (e.g. it is impossible to retrieve the last triggered
watchpoint with it), that's why I have implemented a slightly different
interface in the `RegisterContextWindows`. Moreover, I have made the
`ProcessWindows` plugin responsible for search of a vacant watchpoint slot,
because watchpoints exist per-process (not per-thread), then we can place
the same watchpoint in the same slot in different threads. With this scheme
threads don't need to have their own watchpoint lists, and it simplifies
identifying of the last triggered watchpoint.

Patch by Martin Andersson (martin.andersson@evoma.se)
If the process is resumed before the state is changed to "running"
there is a possibility (when single stepping) that the debugger stops
and changes the state to "stopped" before it is first changed to
"running". This causes the process to ignore the stop event (since
the state did not change) which in turn leads the DebuggerThread to
wait indefinitely for the exception predicate in HandleExceptionEvent.

Summary:
This change extracts functionalities from processwindows into a
introduced processdebugger that can be reused in native process
debugging.
The main reason is that the native process debugging
can't directly be based on processwindows or be implemented
as a pass-through to this plugin since the plugin has ties to
Target and Process classes that are needed in host debugging but
not necessary in native debugging.

A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.
Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.
I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

Add a flag to control whether the ModulesDidLoad notification is
called when a module is added. If the notifications are disabled,
the caller must call ModulesDidLoad after adding all the new modules,
but postponing this notification until they're all batched up can
allow for better efficiency than notifying one-by-one.
Change the name of the ModuleList notifier functions that a subclass
can implement to start with 'Notify' to make it clear what they are.
Add a NotifyModulesRemoved.
Add header documentation for the changed/updated methods.
Added defaulted-value 'notify' argument to ModuleList Append,
AppendIfNeeded, and Remove because callers working with a local
ModuleList don't have an obvious idea of what notify means in this
context. When the ModuleList is a part of the Target class, the
notify behavior matters.
DynamicLoaderDarwin has been updated so that libraries being
added/removed are correctly batched up before notifications are
sent. Added the TestModuleLoadedNotifys.py test to run on
Darwin to test this.

Summary:
When a process is loaded, update its sections with the load address to resolve any created breakpoints. For the remote debugging case, the debugged process is launched remotely so GetLoadAddress is intended to pass the load address from remote to LLDB (client).

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.
