upgraded ngx_lua to 0.9.12rc1.
dist-check: more tolerant about release numbers.
feature: added new command-line utility, "resty", to run Lua code or Lua files (for OpenResty) directly from the command-line. it is installed into the "<prefix>/bin" directory. prodded by Vitaly Kosenko.
resty: more configuration love.
resty: added the -V option.
resty: made the usage text more concise.
resty: added bug report info to the "resty" utility's usage output.
resty: removed the redundant child process reaping code, which also fixes a warning reported by Anton Heryanto.
resty: use the nameservers in /etc/resolv.conf; if none, default to google's 2 open DNS servers, 8.8.8.8 and 8.8.4.4.
resty: made ngx.print, ngx.say, and print return meaninful values; also mocked ngx.flush() and ngx.eof().
resty: made ngx.say, ngx.print, and print accept the same types of arguments as ngx_lua's default.
resty: added -I dir for adding dir to Lua module search paths.
resty: more improvements.

* made ngx.exit() an alias of os.exit().
* made the exit status code right for the wrapper process.
* require at least ngx_lua 0.9.12 to prevent memory bugs in older
  versions.
* suppressed a debugging output line.
updated tests to reflect recent changes.
bugfix: we might misuse the homebrew version of LuaJIT on Mac OS X when the user specified the --with-ld-opt="-L/usr/local/lib". thanks Aapo Talvensaari for the report.
