dlloader documentation update

[Peter Rosin]

Hi,

Recently (when I wrote the testcase for error reporting
in the loadlibrary loader) I found that the documentation
for the dlloader section of the api was a wee bit lacking
in accuracy...

So, I set out to update it, see attached patch.

When going through this, I found it strange that
lt_dlloader_add didn't call vtable->dlloader_init. Isn't
that desirable? I'll send an additional patch to show what
I mean...

Cheers,
Peter
