Changes between 1.6.20060731 and 1.6.200608xx (2006-07-31 to 2006-08-xx)
+ o 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.

o Be more clean and replace weak "#if JS_HAS_FILE_OBJECT" constructs
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
