This patch tries to fix the following build failure on windows:
https://lab.llvm.org/buildbot/#/builders/141/builds/1083
This started happening following 2914a4b88837, and it seems to be caused
by some special `#include` ordering for the lldb-python header on Windows.

CommandObjectParsed (#70734)
This allows you to specify options and arguments and their definitions
and then have lldb handle the completions, help, etc. in the same way
that lldb does for its parsed commands internally.
This feature has some design considerations as well as the code, so I've
also set up an RFC, but I did this one first and will put the RFC
address in here once I've pushed it...
Note, the lldb "ParsedCommand interface" doesn't actually do all the
work that it should. For instance, saying the type of an option that has
a completer doesn't automatically hook up the completer, and ditto for
argument values. We also do almost no work to verify that the arguments
match their definition, or do auto-completion for them. This patch
allows you to make a command that's bug-for-bug compatible with built-in
ones, but I didn't want to stall it on getting the auto-command checking
to work all the way correctly.
As an overall design note, my primary goal here was to make an interface
that worked well in the script language. For that I needed, for
instance, to have a property-based way to get all the option values that
were specified. It was much more convenient to do that by making a
fairly bare-bones C interface to define the options and arguments of a
command, and set their values, and then wrap that in a Python class
(installed along with the other bits of the lldb python module) which
you can then derive from to make your new command. This approach will
also make it easier to experiment.
See the file test_commands.py in the test case for examples of how this
works.

(#71260)
This patch enforces that every scripted object implements all the
necessary abstract methods.
Every scripted affordance language interface can implement a list of
abstract methods name that checked when the object is instanciated.
Since some scripting affordances implementations can be derived from
template base classes, we can't check the object dictionary since it
will contain the definition of the base class, so instead, this checks
the scripting class dictionary.
Previously, for the various python interfaces, we used
`ABC.abstractmethod` decorators but this is too language specific and
doesn't work for scripting affordances that are not derived from
template base classes (i.e OperatingSystem, ScriptedThreadPlan, ...), so
this patch provides generic/language-agnostic checks for every scripted
affordance.

This patch adds the ability to pass native types from the script
interpreter to methods that use a {SB,}StructuredData argument.
To do so, this patch changes the `ScriptedObject` struture that holds
the pointer to the script object as well as the originating script
interpreter language. It also exposes that to the SB API via a new class
called `SBScriptObject`.
This structure allows the debugger to parse the script object and
convert it to a StructuredData object. If the type is not compatible
with the StructuredData types, we will store its pointer in a
`StructuredData::Generic` object.
This patch also adds some SWIG typemaps that checks the input argument to
ensure it's either an SBStructuredData object, in which case it just
passes it throught, or a python object that is NOT another SB type, to
provide some guardrails for the user.

This patch refactors the `StructuredData::Integer` class to make it
templated, makes it private and adds 2 public specialization for both
`int64_t` & `uint64_t` with a public type aliases, respectively
`SignedInteger` & `UnsignedInteger`.
It adds new getter for signed and unsigned interger values to the
`StructuredData::Object` base class and changes the implementation of
`StructuredData::Array::GetItemAtIndexAsInteger` and
`StructuredData::Dictionary::GetValueForKeyAsInteger` to support signed
and unsigned integers.
This patch also adds 2 new `Get{Signed,Unsigned}IntegerValue` to the
`SBStructuredData` class and marks `GetIntegerValue` as deprecated.
Finally, this patch audits all the caller of `StructuredData::Integer`
or `StructuredData::GetIntegerValue` to use the proper type as well the
various tests that uses `SBStructuredData.GetIntegerValue`.

While debugging a Scripted Process, in order to update its state and
work nicely with lldb's execution model, it needs to toggle its private
state from running to stopped, which will result in broadcasting a
process state changed event to the debugger listener.
Originally, this state update was done systematically in the Scripted
Process C++ plugin, however in order to make scripted process
interactive, we need to be able to update their state dynamically.
This patch makes use of the recent addition of the
SBProcess::ForceScriptedState to programatically, and moves the
process private state update to the python implementation of the resume
method instead of doing it in ScriptedProcess::DoResume.
This patch also removes the unused ShouldStop & Stop scripted
process APIs, and adds new ScriptedInterface transform methods for
boolean arguments. This allow the user to programmatically decide if
after running the process, we should stop it (which is the default setting).

The GIL must be held when calling any Python C API functions. In multithreaded applications that use callbacks this requirement can easily be violated by accident. A general tool to ensure GIL health is not available, but patching Python Py_INCREF to add an assert provides a basic health check:
```
+int PyGILState_Check(void); /* Include/internal/pystate.h */
+
#define Py_INCREF(op) ( \
+ assert(PyGILState_Check()), \
_Py_INC_REFTOTAL _Py_REF_DEBUG_COMMA \
((PyObject *)(op))->ob_refcnt++)
#define Py_DECREF(op) \
do { \
+ assert(PyGILState_Check()); \
PyObject *_py_decref_tmp = (PyObject *)(op); \
if (_Py_DEC_REFTOTAL _Py_REF_DEBUG_COMMA \
--(_py_decref_tmp)->ob_refcnt != 0) \
```
Adding this assertion causes around 50 test failures in LLDB. Adjusting the scope of things guarded by `py_lock` fixes them.

It is surprisingly difficult to write a simple python script that
can reliably `import lldb` without failing, or crashing. I'm
currently resorting to convolutions like this:
def find_lldb(may_reexec=False):
if prefix := os.environ.get('LLDB_PYTHON_PREFIX'):
if os.path.realpath(prefix) != os.path.realpath(sys.prefix):
raise Exception("cannot import lldb.\n"
f" sys.prefix should be: {prefix}\n"
f" but it is: {sys.prefix}")
else:
line1, line2 = subprocess.run(
['lldb', '-x', '-b', '-o', 'script print(sys.prefix)'],
encoding='utf8', stdout=subprocess.PIPE,
check=True).stdout.strip().splitlines()
assert line1.strip() == '(lldb) script print(sys.prefix)'
prefix = line2.strip()
os.environ['LLDB_PYTHON_PREFIX'] = prefix
if sys.prefix != prefix:
if not may_reexec:
raise Exception(
"cannot import lldb.\n" +
f" This python, at {sys.prefix}\n"
f" does not math LLDB's python at {prefix}")
os.environ['LLDB_PYTHON_PREFIX'] = prefix
python_exe = os.path.join(prefix, 'bin', 'python3')
os.execl(python_exe, python_exe, *sys.argv)
lldb_path = subprocess.run(['lldb', '-P'],
check=True, stdout=subprocess.PIPE,
encoding='utf8').stdout.strip()
sys.path = [lldb_path] + sys.path
This patch aims to replace all that with:
#!/usr/bin/env lldb-python
import lldb
...
... by adding the following features:
* new command line option: --print-script-interpreter-info. This
prints language-specific information about the script interpreter
in JSON format.
* new tool (unix only): lldb-python which finds python and exec's it.

This is mostly mechanical from a custom clang-tidy check, with a lot of

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Summary:
This patch updates the last user of ArgInfo::count and deletes
it. I also delete `GetNumInitArguments()` and `GetInitArgInfo()`.
Classess are callables and `GetArgInfo()` should work on them.
On python 3 it already works, of course. `inspect` is good.
On python 2 we have to add yet another special case. But hey if
python 2 wasn't crufty we wouln't need python 3.
I also delete `is_bound_method` becuase it is unused.
This path is tested in `TestStepScripted.py`

Summary:
When users define a debugger command from python, they provide a callable
object. Because the signature of the function has been extended, LLDB
needs to inspect the number of parameters the callable can take.
The rule it was using to decide was weird, apparently not tested, and
giving wrong results for some kinds of python callables.
This patch replaces the weird rule with a simple one: if the callable can
take 5 arguments, it gets the 5 argument version of the signature.
Otherwise it gets the old 4 argument version.
It also adds tests with a bunch of different kinds of python callables
with both 4 and 5 arguments.

This patch leaves the old implementation in place for < 3.3,
but uses inspect.signature for modern pythons. It also leaves
the old weird semantics in place, but with FIXMEs grousing about

It will also sometimes, but not usually result in crashes of

Nearly everything in PythonDataObjects.h needs to be updated

Currently this is impossible because python file objects must first
be converted into FILE* streams by SWIG in order to be passed into
