[PATCH] libosmocore[master]: add osmo_fd_setup() convenience function to fill-in osmo_fd

[Harald Welte]

Review at  https://gerrit.osmocom.org/3500

add osmo_fd_setup() convenience function to fill-in osmo_fd

This basically follows the concept of osmo_timer_setup() and allows
the caller to fill-in all configurable fields of osmo_fd in one
line of code, rather than open-coding it in 5 lines everywhere.
