Summary:
This patch marks the inline namespaces from DWARF as inline and also ensures that looking
up declarations now follows the lookup rules for inline namespaces.

The RECORD macro is context sensitive because it depends on the
LLDB_GET_INSTRUMENTATION_DATA. This updates the modulemap to mark that
header as textual.

Apparently the log_append variant added in r355863 is considered
ambiguous. At this point I'm out of ideas so a good old reinterpret cast
will have to do. If anybody has a better idea I'd be happy to hear it.

Changing the type in the DUMMY macro to void* doesn't actually fix the
build error, because the argument type is deducted from the template (as
opposed to when serializing through the instrumentation framework, where
this would matter). Instead I've added a proper instance of log_append
that takes function pointers and logs their address.

There was a crash that would happen if an IDE would ask for a child of a shared pointer via any SB API call that ends up calling StackFrame::GetValueForVariableExpressionPath(). The previous code expects an error to be set describing why the synthetic child of a type was not able to be found, but we have some synthetic child providers that weren't setting the error and returning an empty value object shared pointer. This fixes that to ensure we don't lose our debug session by crashing, fully tests GetValueForVariableExpressionPath functionality, and ensures we don't crash on GetValueForVariableExpressionPath() in the future.

Callbacks in the LLDB_RECORD_DUMMY macros were causing build failures
with the Xcode project. This patch replaces the function pointers with
void pointers so they can be logged.

Summary:
Our python version of the SB API has (the python equivalent of)
operator bool, but the C++ version doesn't.
This is because our python operators are added by modify-python-lldb.py,
which performs postprocessing on the swig-generated interface files.
In this patch, I add the "operator bool" to all SB classes which have an
IsValid method (which is the same logic used by modify-python-lldb.py).
This way, we make the two interfaces more constent, and it allows us to
rely on swig's automatic syntesis of python __nonzero__ methods instead
of doing manual fixups.

the input StringRef is not guaranteed to be null-terminated, so using
data to get the c string is wrong. Luckily, in two of the usages the
target function already accepts a StringRef so we can just drop the
data() call, and the third one is easily replaced by a stringref-aware
function.
Issue found by msan.

Summary:
Within .lldbinit, regex commands can be structured as a list of substitutions over
multiple lines. It's possible that this is uninentional, but it works and has
benefits.
For example:
command regex <command-name>
s/pat1/repl1/
s/pat2/repl2/
...
I use this form of `command regex` in my `~/.lldbinit`, because it makes it
clearer to write and read compared to a single line definition, because
multiline substitutions don't need to be quoted, and are broken up one per line.
However, multiline definitions result in usage instructions being printed for
each use. The result is that every time I run `lldb`, I get a dozen or more
lines of noise. With this change, the instructions are only printed when
`command regex` is invoked interactively, or from a terminal, neither of which
are true when lldb is sourcing `~/.lldbinit`.

This is not a fix, but if I understand enough of the issue, it should

Fix the NetBSD core test not to verify libc function names in backtrace.
This obviously requires the same libc.so as originally used to produce
the core file, and so it is going to fail everywhere except on my

Improve the support for processing NetBSD cores. Fix reading process

with the correct thread.
Includes test cases for single-threaded program receiving SIGSEGV,
and two dual-threaded programs: one where thread receives the signal,
and the other one when the whole process is signalled.

Add a macro that doesn't actually record anything but still toggles the
API boundary. Removing just the register macros for lldb::thread_t
wasn't sufficient on NetBSD because the serialization logic needed the
underlying type to be complete.
This macro should be used by functions that are currently unsupported,
as they might trip the API boundary logic. This should be easy using the
lldb-instr tool.

I changed the variable to an unsigned to get rid of a signed and

The last round of logging taught us that when the test fails, lldb
is indeed aware of the thread it's failing to associate to a given
queue. Add more logging to try to figure out why the thread and the
queue do not appear related to the Queue APIs.

The overload and/or template specialization are regular functions and
should be marked inline when implemented in the header. Writing the
previous commit message should've made that obvious but I was already
overthinking it. This will fix the windows bot.

Previously if an invalid program was specified, there was a bug
which, when we attempted to launch the program, would report that
the operation succeeded, causing LLDB to then hang while waiting
indefinitely to receive some events from the process.
After this patch, when an invalid program is specified, we immediately
return to vs code with an error message that indicates that the
program can not be found.

The current record macros already log the function being called. This
patch extends the macros to also log their input arguments and removes
explicit logging from the SB API.
This might degrade the amount of information in some cases (because of
smarter casts or efforts to log return values). However I think this is
outweighed by the increased coverage and consistency. Furthermore, using
the reproducer infrastructure, diagnosing bugs in the API layer should
become much easier compared to relying on log messages.

I committed an implementation of GetClangResourceDir on windows but
forgot to update this test. I merged the tests like I intended to, but I
realized that the test was actually failing. After looking into it, it
appears that FileSystem::Resolve was taking the path and setting
the FileSpec's Directory to "/path/to/lldb/lib/clang/" and the File to
"9.0.0" which isn't what we want. So I removed the resolve line from
DefaultComputeClangResourceDir.

Windows can't use standard i/o system calls such as read and write
to work with sockets, it instead needs to use the specific send
and recv calls. This complicates matters for the debug adapter,
since it needs to be able to work in both server mode where it
communicates over a socket, as well as non-server mode where it
communicates via stdin and stdout. To abstract this out, I've
introduced a class IOStream which hides all these details and
exposes a read/write interface that does the right on each
platform.
