Added tests and fixed bugs * 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.
