Jonas Devlieghere 127faae752 [lldb] Add -l/--language option to script command
Make it possible to run the script command with a different language
than currently selected.

  $ ./bin/lldb -l python
  (lldb) script -l lua
  >>> io.stdout:write("Hello, World!\n")
  Hello, World!

When passing the language option and a raw command, you need to separate
the flag from the script code with --.

  $ ./bin/lldb -l python
  (lldb) script -l lua -- io.stdout:write("Hello, World!\n")
  Hello, World!

Jonas Devlieghere fa1b4a96a0 [lldb/Lua] Use the debugger's output and error file for Lua's I/O library.
Add support for changing the stdout and stderr file in Lua's I/O library
and hook it up with the debugger's output and error file respectively
for the interactive Lua interpreter.

Jonas Devlieghere 1728dec255 [lldb/Lua] Recognize "quit" as a way to exit the script interpreter.
Add a way to quit the interactive script interpreter from a shell tests.
Currently, the only way (that I know) to exit the interactive Lua
interpreter is to send a EOF with CTRL-D. I noticed that the embedded
Python script interpreter accepts quit (while the regular python
interpreter doesn't). I've added a special case to the Lua interpreter
to do the same.

Jonas Devlieghere 94ec56b6d5 [lldb/Test] Use lit.local.cfg to mark whole directory as (un)supported.
Mark the whole Python or Lua test directory as unsupported when the
corresponding language is not available.

Jonas Devlieghere 6ae61f7675 [lldb/Test] Skip script interpreter tests reading from stdin for lldb-repro
The reproducers currently only shadow the command interpreter. It would
be possible to make it work for the Lua interpreter which uses the
IOHandlerEditline under the hood, but the Python one runs a REPL in
Python itself so there's no (straightforward) way to shadow that.

Given that we already capture any API calls, this isn't super high on my
list of priorities.

Jonas Devlieghere 45c971f7ee [lldb/Lua] Make lldb.debugger et al available to Lua
The Python script interpreter makes the current debugger, target,
process, thread and frame available to interactive scripting sessions
through convenience variables. This patch does the same for Lua.

Jonas Devlieghere 4164be7206 [Lldb/Lua] Persist Lua state across script interpreter calls.
Don't create a new lua state on every operation. Share a single state
across the lifetime of the script interpreter. Add simple locking to
prevent two threads from modifying the state concurrently.

Jonas Devlieghere bf03e17c57 [Lldb/Lua] Generate Lua Bindings
This patch uses SWIG to generate the Lua bindings for the SB API. It
covers most of the API, but some methods require a type map similar to
Python.

Jonas Devlieghere 2861324208 [lldb/Lua] Implement a Simple Lua Script Interpreter Prototype
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.
