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

Instead of building debugserver when building lldb, I'd rather pass
LLDB_CODESIGN_IDENTITY="" to cmake and use the one already on my system.
However, on one of my machines I only have the CommandLineTools installed, and
so the hardcoded path to the system debugserver does not work for me.
Additionally, we should verify the LLDB framework exists on the machine before
trying to set the path to debugserver. This allows us to warn the user at
configure time that a system debugserver can't be found if they choose not to
build it themselves.

1. Link against libpmenergy and pmsample unconditionally. It is available on
macOS 10.10 ("Yosemite") and newer. We're already linking against libcompression
unconditionally which is only available on macOS 10.11 & newer.
2. Change a few "sdk=macosx.internal"'s to sdk=macosx.
3. Clean up a few places where libcompression was being enabled inconsistently.
Note: the -DLLDB_ENERGY define is only set when building against the macosx.internal
SDK; it includes a header file that is not public. We link against the dylibs
unconditionally for simplicity.

Also including the debugserver bridgeos support, another arm
environment that runs Darwin akin to ios. These codepaths are
activated when running in a bridgeos environment which we're not
set up to test today.
There's additional (small) lldb changes to handle bridgeos binaries
that still need to be merged up.
Tested on a darwin system with avx512 hardware and without.

The lldb-server unit tests don't test the right thing when the debug
server in use is copied from somewhere else. This can lead to spurious
test failures.
Disable these unit tests when an external debug server is in use.
Fixes llvm.org/PR36494.

Summary:
Consolidate LLDB_CODESIGN_IDENTITY logic in one place and use
SKIP_DEBUGSERVER, which can be set independently, to control
codesigning targets.
Currently, running cmake the first time in a clean directory, without
passing -DLLDB_CODESIGN_IDENTITY='', fails. However, subsequent runs
succeed. That's because LLDB_CODESIGN_IDENTITY gets added to the
CACHE after the initial test. To fix that, the default value must be
set before it's tested.
Here's the error produced on the first run:
CMake Error at tools/lldb/tools/debugserver/source/CMakeLists.txt:215 (add_custom_command):
No TARGET 'debugserver' has been created in this directory.

(built with Xcode) from 10.9 to 10.11. It also enables the use of
libcompression in debugserver by default (these API are only present
in macOS 10.11 and newer -- 10.11 was released c. Sep 2015).
I don't know if we have people / bots building lldb on older mac
releases; if this turns out to be a problem I will revert the change.
There are some parts of lldb (e.g. debugserer's ability to report
the OS version #) that only work with 10.10 and this changes the
behavior of lldb (whether the older or newer dyld interfaces are
used) so there is some importance to updating the min required
version.

Summary:
Make sure we propagate environment when starting debugserver with a pre-loaded
inferior. AFAIK, RNBRunLoopLaunchInferior is only called in pre-loaded inferior
scenario, so we can just pick up the debugserver environment instead of trying
to construct an envp from the (empty) context.
This makes debugserver pass an test added for an equivalent lldb-server fix.

Null-checking functions which aren't marked weak_import is a no-op
(the compiler rewrites the check to 'true'), regardless of whether a
library providing its definition is weak-linked. If the deployment
target is greater than the minimum requirement, the availability markup
on APIs does not lower to weak_import.
Remove no-op null checks to clean up the code and silence warnings.

Turns out WITH_LOCKDOWN define changes the struct layout and constructor implementation for RNBSocket which is used in debugserver.cpp, so we need to make sure this is consistent.

When building for iOS we build two variants of debugserver. One which supports UI functionality like Springboard for launching applications, and one which does not.
This patch adds support for building debugserver with and without UI support libraries being available.

This refactoring changes two significant things about how the debugserver build system works:
(1) debugserver will include all appropriate architecture support, so we can now build arm or ppc debugservers
(2) debugserver can be built by itself, so you don't have to configure all of LLDB in order to generate debugserver.
