NSBundle - supporting foreign bundles

[Luboš Doležel]

Hi,

for proper support of non-native (OS X) bundles on Linux/Darling, I 
need some changes in NSBundle.
I've looked into GNUstep's code and I can achieve most stuff with 
various tricks. But some things would lead to unnecessary code 
duplication and that's where I'd like to ask you whether a patch would 
be acceptable.

=======
1)
I'd like to add

+[NSBundle _addFrameworkFromClassWithPath: (Class)frameworkClass 
:(NSString*)path]

which would obviously be an extended version of _addFrameworkFromClass 
with the only change: it would use the path passed in arguments unless 
NULL. This is needed because dladdr() won't work for OS X dynamic 
libraries loaded by Darling.
I think this change is very unintrusive.

=======

2)
GSPrivateLoadModule() also contains platform-specific things. Would it 
be acceptable to add [self _loadModule: .....] called from -load that 
would in GNUstep simply call GSPrivateLoadModule()?
This would enable me to override -[NSBundle _loadModule] and let myself 
decide whether to use GNUstep's mechanisms or my own.

=======

Thanks!
