Adrian's changes to support Catalyst processes and my
changes to support debugserver running on an arm64_32
device (Apple Watch Series 4, which uses an IPL32 model
on arm64 cpus).

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.

event as a thread stop reason if we receive one, using
some macros to decode the payload.
Patch originally written by Fred Riss, with a few small changes
by myself.
Writing a test for this is a little tricky because the
mach exception data interpretation relies on header macros
or function calls - it may change over time and writing
a gdb_remote_client test for this would break as older
encoding interpretation is changed. I'll tak with Fred
about this more, but neither of us has been thrilled with
the kind of tests we could write for it.

Summary:
When a MIG routine returns KERN_FAILURE, the demux function will release any OOL resources like ports. In this case, task_port and thread_port will be released twice, potentially resulting in use after free of the ports.
I don't think we can test this in any useful way

Fix alignment UB in some Mach exception-handling logic.
This lets us build lldb and debugserver with UBSan in trapping mode, and
get further along in the testing process before a trap is encountered.

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.
A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error". Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around. Hopefully nothing too
serious.

*** 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.

Changed the "jthreads" key/value in the stop reply packets to be "jstopinfo". This JSON only contains threads with valid stop reasons and allows us not to have to ask about other threads via qThreadStopInfo when we are stepping. The "jstopinfo" only gets sent if there are more than one thread since the stop reply packet contains all the info needed for a single thread.
Added a Process::WillPublicStop() in case process subclasses want to do any extra gathering for public stops. For ProcessGDBRemote, we end up sending a jThreadsInfo packet to gather all expedited registers, expedited memory and MacOSX queue information. We only do this for public stops to minimize the packets we send when we have multiple private stops. Multiple private stops happen when a source level single step, step into or step out run the process multiple times while implementing the stepping, and none of these private stops make it out to the UI via notifications because they are private stops.

On darwin, if child process of process being debugged dies due to mach exception, the debugged process will die.
debugserver now only handles the mach exceptions for the task being debugged.
