This backport needs to be reworked. Concretely, introduction of new header file event-source.h is fine but it needs to be paired with appropriate removals of type definitions from sd-event.c. Now we have everything declared twice which is wrong.

Oops, that's a mistake. Apparently I've forgotten to remove it after I'd copied the needed stuff to sd-event.c.

sd-event: don't destroy inotify data structures from inotify event ha…
b0ad8db 
…ndler

This fixes a bad memory access when we destroy an inotify source handler
from the handler itself, and thus destroy the associated inotify_data
structures.

Fixes: #20177
(cherry picked from commit 53baf2e)

Resolves: #2211358
@poettering @dtardon
sd-event: add sd_event_add_inotify_fd() call
c199aeb 
sd_event_add_inotify_fd() is like sd_event_add_inotify(), but takes an
fd to an inode instead of a path, and is hence a ton nicer.

(cherry picked from commit e67d738)
