js: upgrade to version 1.8.0~rc1

from 1.5
use version string 1.7.0+1.8.0rc1
aka. spidermonkey

changes:
  - rebase jsautocfg.h to add JS_HAVE_LONG_LONG, fixing the build
    failure
  - document the limitation of jsautocfg.h
  - jskwgen is a host script, and should be built by BUILD_CC
  - remove dependency of readline. readline or editline is only
    used in standalone js command line, which is not shipped in
    package. Removing the dependency to avoid any concern of
    GPL3-ization
  - set BUILD_OPT=1 for optimized build

Note on version choice:
   js is known to have long rc cycles. e.g. the version 1.5:
     js-1.5-b1:   12/16/1999,  js-1.5-rc1:     03/17/2000,
     js-1.5-rc6a: 06/16/2004,  js-1.5 release: 10/22/2005

   Current release version is 1.7.0: 10/19/2007, latest version
   1.8.0-rc1: 03/09/2009, so 1.8.0-rc1 is used.

Note on standalone js vs. xulrunner:
   xulrunner also includes a js version, that is more updated than
   standalone spidermonkey. It also uses autotools so jsautocfg.h
   patch may not be necessary. However the version of xulrunner is
   different from js, and it's difficult to identify the mapping
   between them. It needs further investigation on xulrunner's
   bundled js
