Loading dependent libs and the GRE: revisited

[Benjamin Smedberg]

Doug, I have come up with a way to package the GRE on linux (at least 
for testing purposes), and I am still running up against the problem of 
loading dependent libraries. It's a catch-22: you don't know what the 
dependent libs are until you load the component, but you can't load it 
until you've loaded the dependent libs. I have come up with several 
possible solutions, and wanted to run them by you for discussion:

1) keep the current dependent lib mechanism (notify during 
auto-registration); before autoregistration, all of the GRE libraries 
should be pre-loaded (path.to.gre/*.so or something else?).

2) revamp the current dependencies-at-autoregistration mechanism. 
Instead, keep a text file next to each component (libcomponent.deps) 
with a list of dependent libs.

3) don't use the c++ glue to find a GRE; instead, find a compatible GRE 
in the run-mozilla.sh script. This may sound hacky, but I think it would 
work pretty well. It would probably require awk or something; I'm not 
sure whether it would be onerous to require awk at runtime.

I personally like #2... let me know what/whether any of these sounds 
good to you.
