the xcode project file for debugserver exists only to make my
life easier when I'm working only on debugserver and don't need
to build the rest of llvm/lldb. It had many build configurations
to reflect our old lldb xcode project file, which is long gone.
Removing them to simplify the configurations.
Specifically dropping CustomSwift-Debug, DebugClang, DebugPresubmission,
CustomSwift-Release, BuildAndIntegration. Keeping Debug & Release.
Link against CarouselServices on watchos, recognize the
WatchComplicationLaunch launch flag option when that framework
is available.

Extract a function for turning `eLaunchFlavorDefault` into a concreate `eLaunchFlavor` value.
This new function encapsulates the few compile time variables involved, and also prevents clang unused code diagnostics.

If our process terminates due to an unhandled signal, we are supposed to get the
signal code via WTERMSIG. However, we instead try to get the exit status via
WEXITSTATUS which just ends up always calculating signal code 0 (at least on the
macOS implementation where it just shifts the signal code bits away and we're
left with only 0 bits).
The exit status calculation on the LLDB side also seems a bit off as it claims
an exit status that is just the signal code (instead of for example 128 + signal
code), but that will be another patch.

This patch configures LLDB.framework to build as a flat unversioned
framework on non-macOS Darwin targets, which have never supported the
macOS framework layout.
This patch also renames the 'IOS' cmake variable to 'APPLE_EMBEDDED' to
reflect the fact that lldb is built for several different kinds of embedded
Darwin targets, not just iOS.

This patch is similar in spirit to https://reviews.llvm.org/D84480,
but does the maccatalyst/macosx disambiguation. I also took the
opportunity to factor out the gdb-remote packet log scanning used by
several testcases into lldbutil functions.

On an iOS device, if debugserver is left to figure out how to launch
the binary provided, it looks at the filename to see if it contains
".app" and asks FrontBoard to launch it. However, if this is actually
a command line app with the characters ".app" in the name, it would
end up trying to launch that via the FrontBoard calls even though it
needed to be launched via posix_spawn. For instance, a command line
program called com.application.tester.
Jim suggested this patch where we only send binaries that end in ".app"
to FrontBoard.
Often debugsever is invoked with a --launch command line argument to
specify the launch method, and none of this code is hit in that
instance.

This patch basically moves the disambiguation code from a place where
it was complicated to implement straight to where the load command is
parsed, which has the neat side affect of actually supporting all call

If the error message from qLaunchSucess included a gdb RSP
metacharacter, it could crash lldb. Apply the binary
escaping to the string before sending it to lldb; lldb
promiscuously applies the binary escaping protocol on
packets it receives.
Also fix a small bug in cstring_to_asciihex_string where
a high bit character (eg utf-8 chars) would not be
quoted correctly due to signed char fun.

MachProcess.mm uses a TARGET_OS_ macro without directly including
TargetConditionals.h. This currently works as we get the header
as an indirect dependency, but might not in the future.
I just spent some time investigating an internal regression
caused by a similar issue, so I audited the codebase for such
cases.
Similar to
com.apple.debugserver.plist & com.apple.debugserver.internal.plist
com.apple.debugserver.applist.plist & com.apple.debugserver.applist.internal.plist
add a variant of the posix plist.

Update CallBoardSystemServiceOpenApplication to unconditionally log
the NSError's localizedDescription to Console on app launch failure
(as it was already doing), and also to log the NSError object's
full description to the console, which may contain additional nested
error messages. I'm experimenting to find cases where we will get
more detailed information from app launch failures and will start
by logging both to the console.

The SIP debugserver was calling in attach_failed_due_to_sip
haven't worked for a while; remove them. To check this
properly we'd need debugsever to call out to codesign(1) to
inspect the entitlements, or the equivalant API,
and I'm not interested in adding that at this point. SIP
is has been the default on macOS for a couple of releases
and it's expected behavior now.

Summary:
Compiling ObjC++ with Clang modules is usually not working well and compiling
the small debugserver with modules is not worth the trouble.

The debugserver profile thread used to suspend itself between samples with
a usleep. When you detach or kill, MachProcess::Clear would delay replying
to the incoming packet until pthread_join of the profile thread returned.
If you are unlucky or the suspend delay is long, it could take longer than
the packet timeout for pthread_join to return. Then you would get an error
about detach not succeeding from lldb - even though in fact the detach was
successful...
I replaced the usleep with PThreadEvents entity. Then we just call a timed
WaitForEventBits, and when debugserver wants to stop the profile thread, it
can set the event bit, and the sleep will exit immediately.

LLDB has a few different styles of header guards and they're not very
consistent because things get moved around or copy/pasted. This patch

Look up the -arch flags to pass to the mig invocation from an
optionally-defined MIG_ARCHS variable. We can't use CMAKE_OSX_ARCHS
because the {i,tv,watch}OS builds don't use this mechanism to achieve
fat builds (they build each slice separately & then lipo them together).
This supercedes the mig -arch/-isysroot fix from
510758dae2.
