dynamically load packages by prefix
[François Bobot] I would like to propose this patch that adds to the findlib API the ability to only load packages that have a certain prefix. It is very useful in addition to dynload for implementing auto-loading of plugins.
For example the frama-c plugins could be regular ocamlfind libraries
that start with
frama-c-plugins-, and at start-up it could look for
these libraries. Loading all the libraries takes a non negligible time.
