@Add optional Dynamic Shared Object (DSO) support (see src/jsdso.[ch]).
This comes in two flavors:

1. Provide two public C API functions...
   JSBool JS_DSOLoad   (JSContext *cx, int *id, const char *filename);
   JSBool JS_DSOUnload (JSContext *cx, int  id);
   ...as an ultra-thin wrapper around the POSIX dlopen(3) API. It
   especially mimics the BSD RTLD behaviour of calling pre-defined
   functions (mandatory "js_DSO_load" and optional "js_DSO_unload")
   inside the DSO after/before the dlopen/dlclose calls. This
   allows the DSOs to perform their init/shutdown actions.

2. Provide a small JavaScript global object "DSO" which binds
   the two public DSO C API functions into the JavaScript language
   as "DSO.load" and "DSO.unload". The "DSO" object can be created
   by the friend C API function js_InitDSOClass(). This function is
   used by the command-linne interface "js" by default.

As a result the OSSP Mozilla JavaScript engine is now able to
dynamically load C extensions similar to what other programming
languages provide since a longer time.

with the stronger "#if defined(JS_HAS_FILE_OBJECT) && (JS_HAS_FILE_OBJECT - 0)"
as the JS_HAS_FILE_OBJECT can be not defined at all (in contrast to

@o Install all src/js*.h headers during "make install" to allow
  applications to at least optionally poke around in the internals.
  This also allows an application to call js_InitFileClass() from
  <jsfile.h> without us having to really call this function in the
  standard API function JS_InitStandardClasses().

o Change the default of the --with-file/--without from --without-file
  to --with-file (enable the File object by default), but activate
  it only in the CLI (where it doesn't hurt and where it is actually
  really required to get something useful running there in practice)
  but explicitly _NOT_ in JS_InitStandardClasses() (as this is
  what would hurt the security in applications which assume that
  JS_InitStandardClasses() initialized only really the standard
  classes).
