The SSSD needs a config_from_fd() variant of the config_from_file()

conditions between testing the file and reading it in.
Note: the *_from_fd() functions still require the config file name for
internal information. This does not imply that it is used to open the
file.
I think it is better not to require a file name, and, internally, just
use something like "dummy" or a random string like the process pid etc..
This way there is no risk that someone may accidentally change the code
later to re-open the file or something like that, if that is done it
will immediately break when it tries to open "dummy" (hopefully :-)
Simo.
