use autoconf to generate jsautocfg.h instead of preparing
different headers for different archs
size_of and align_of tests also work under cross-compilation.

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
