* Added error backtrace collection to MWServer:handleCall()
* When there is an error on parse, show a short and simple inline error
message to the user, which when clicked, expands to a full error with
HTML-formatted backtrace.
* When an error is encountered during module validation, have the code
editor jump directly to the line. Requires r115011.
* Expose the code location of most errors to Scribunto, by parsing the
standard error message format.
* During module validation, abbreviate the error location if the error
is in the same module.
* Do not execute the module during validation, just parse it. Execution
does not really work without an active parse operation in progress.
It already caused a fatal error if you called require() from the main
chunk, and problems would have become more visible as more
parser-related APIs were added.
* LuaSandbox does not yet provide backtraces, but this is planned.

* Added unit tests for the two Lua interpreter classes
* Fixed a bug in checkType()
* Have Scribunto_LuaSandboxInterpreter throw an exception on construct
when the extension doesn't exist, to match the standalone behaviour.
* In Scribunto_LuaSandboxInterpreter, removed debugging statements
accidentally left in.
* Convert LuaSandboxTimeoutError to the appropriate common error
message.
* Moved the option munging from the sandbox engine to the interpreter,
so that the interpreter can be unit tested separately.
* Use /bin/sh instead of bash for lua_ulimit.sh, since dash is smaller
and still supports ulimit.
* Use exec to run the lua binary, so that the vsize of the shell doesn't
add to the memory limit.
* Added a quit function to the standalone interpreter. Unused at present.
* Don't add a comma after the last element of a table in a Lua
expression.
* Make the SIGXCPU detection work: proc_open() runs the command via a
shell, which reports signals in the child via the exit status, so
proc_get_status() will never return a valid termsig element.
* In MWServer:call(), fixed a bug causing the return values to be
wrapped in an array.
* Fixed a misunderstanding of what select() does.
* In MWServer:getStatus(), fixed indexes so that vsize will be correct.
Removed RSS, since it wasn't used anyway and turns out to be measured
in multiples of the page size, and I couldn't be bothered trying to
fetch that from getconf. Return the PID and vsize as numbers rather
than strings.
* Added a simple table dump feature to MWServer:debug().
* Fixed brackets in MWServer:tostring().
* Added missing Linux 32-bit binary.

* Introduced a Lua implementation based on shelling out to a standard Lua binary.
* Bundled several Lua binaries for common platforms. I haven't added a 32-bit Linux binary yet, but that will come.
* Refactored the existing Lua class, bringing out functionality common to all Lua implementations into a set of common base classes.
* Moved the bulk of the implementation-specific functionality into a set of "interpreter" classes.
* Renamed LuaSandboxEngine to Scribunto_LuaSandboxEngine
* Don't create an engine object unconditionally when the ParserLimitReport hook is called.
* Implemented isolation of module global variable namespaces. This means that separate {{#invoke}} calls can't pass data to each other -- this was a desired feature in planning since it allows more flexibility in wikitext parser design. Isolation for mw.import() means that modules cannot accidentally create global variables which affect other modules -- exports are solely via the return value.
