Discussed on lldb-dev with Pavel Labath. This doesn't work for
background processes [causes Python to be stuck forever], and it's
unclear whether it's needed. There's no test, also. If this turns
out to be useful, it can be recommitted with a functional implementation
and a test.
Files imported by the script interpreter aren't opened by LLDB so they
don't end up in the reproducer. The solution is to explicitly add them
to the FileCollector.

This change allows a hard coded relative PYTHONHOME setting. So that
python can easily be packaged together with lldb.
The change includes:
1. Extend LLDB_RELOCATABLE_PYTHON to all platforms. It defaults to ON
for platforms other than Windows, to keep the behavior compatible.
2. Allows to customize LLDB_PYTHON_HOME. But still defaults to
PYTHON_HOME.
3. LLDB_PYTHON_HOME can be a path relative to liblldb. If it is
relative, we will resolve it before send it to Py_DecodeLocale.

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Don't create a new lua state on every operation. Share a single state

prevent two threads from modifying the state concurrently.
This implements a very elementary Lua script interpreter. It supports
running a single command as well as running interactively. It uses
editline if available. It's still missing a bunch of stuff though. Some
things that I intentionally ingored for now are that I/O isn't properly
hooked up (so every print goes to stdout) and the non-editline support
which is not handling a bunch of corner cases. The latter is a matter of
reusing existing code in the Python interpreter.

For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and
it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no
way to write a generic "stop when my caller is..." function, and then specify the caller when you add the
command to a breakpoint.
With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in
the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right
signature) when the breakpoint is hit. Then in lldb, you can say:
(lldb) break com add -F caller_is -k caller_name -v Foo
More generally this will allow us to write reusable Python breakpoint commands.

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.

friends when LLDB runs a python script.
It currently does this using FILE*, which is not optimal. If
whatever was in sys.stdout can not be represented as a FILE*, then
it will not be restored correctly when the script is finished.
It also means that if the debugger's own output stream is not
representable as a file, ScriptInterpreterPython will not be able
to redirect python's output correctly.
This patch updates ScriptInterpreterPython to represent files with
lldb_private::File, and to represent whatever the user had in
sys.stdout as simply a PythonObject.
This will make lldb interoperate better with other scripts or programs

Summary:
This patch removes File::SetStream() and File::SetDescriptor(),
and replaces most direct uses of File with pointers to File.
Instead of calling SetStream() on a file, we make a new file and
replace it.
My ultimate goal here is to introduce a new API class SBFile, which
has full support for python io.IOStream file objects. These can
redirect read() and write() to python code, so lldb::Files will
need a way to dispatch those methods. Additionally it will need some
form of sharing and assigning files, as a SBFile will be passed in and
assigned to the main IO streams of the debugger.
In my prototype patch queue, I make File itself copyable and add a
secondary class FileOps to manage the sharing and dispatch. In that
case SBFile was a unique_ptr<File>.
(here: https://github.com/smoofra/llvm-project/tree/files)
However in review, Pavel Labath suggested that it be shared_ptr instead.
(here: https://reviews.llvm.org/D67793)
In order for SBFile to use shared_ptr<File>, everything else should
as well.
If this patch is accepted, I will make SBFile use a shared_ptr
I will remove FileOps from future patches and use subclasses of File

This is because those parts of LLDB rely on GetStream() to use the
file, and that in turn relies on calling fdopen on the descriptor. When
calling fdopen, GetStream relies on m_options to determine the access
mode. If m_options has never been set, GetStream() will fail.

where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.
I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

This patch limits the scope of the python header to the implementation
of the python script interpreter plugin. ScriptInterpreterPython is now
an abstract interface that doesn't expose any Python specific types, and
is implemented by the ScriptInterpreterPythonImpl.

The utility library shouldn't depend on curses, libedit or python. Move
curses to core, libedit to host and python to the python plugin.

For a single char argument, find_first_of is equal to find and
find_last_of is equal to rfind. While playing around with the plugin
stuff this caused an export failure because it always got inlined except
once, which resulted in an undefined symbol.

The python plugin uses wrappers generated by swig. For the symbols to be
available, we'd need to link against liblldb, which is not an option
because the symbols could conflict with the static library we are
testing. Instead we define the symbols ourselves in the unit test.

With the initialization taking place inside the Python script
interpreter, these function no longer need to be public. The exception
is the g_swig_init_callback which is used from the RAII object.
