4a7cd0caad sd-event: fix sd_event_source_get_inotify_path()
Follow-ups for 74c4231ce5.

Previously, the path is obtained from the fd, but it is closed in
sd_event_loop() to unpin the filesystem.
So, let's save the path when the event source is created, and make
sd_event_source_get_inotify_path() simply read it.

74c4231ce5 sd-event: introduce sd_event_source_get_inotify_path()
This may be useful when there are multiple inotify event sources exist.
Without this, users need to manage the event sources and paths.

13a69c120b man: use <simplelist> for 'See also' sections
This is just a slight markup improvement; there should be no difference
in rendering.

00f95506e2 man: condense version information for functions
Use a more compact form like 'a, b, and c were added in version x'

ec07c3c80b man: add version info
This tries to add information about when each option was added. It goes
back to version 183.

The version info is included from a separate file to allow generating it,
which would allow more control on the formatting of the final output.

2eeff0f4f1 sd-event: store and compare per-module static origin id
sd-event objects use hashmaps, which use module-global state, so it is not safe
to pass a sd-event object created by a module instance to another module instance
(e.g.: when two libraries static linking sd-event are pulled in a single process).
Initialize a random per-module origin id and store it in the object, and compare
it when entering a public API, and error out if they don't match, together with
the PID.

9809a788e4 man: add better descriptions of what event handlers do
The meaning of the return value, the default handlers, and loop exiting are now
described.

e67d738a87 sd-event: add sd_event_add_inotify_fd() call
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.

b9350e70aa sd-event: support callback=NULL in IO/child/inotify/defer event sources, too
Also, document this functionality more prominently, including with a
reference from sd_event_exit().

This is mostly to make things complete, as previously we supported NULL
callbacks only in _add_time() and _add_signal(). However, I think this
makes snese for IO event sources too (think: when some fd such as a pipe
end sees SIGHUP or so, exit), as well as defer or post event sources (i.e. exit
once we got nothing else to do). This also adds support for inotify
event sources, simply to complete things (I can't see the immediate use,
but maybe someone else comes up with it).

The only event source type that doesn't allow callback=NULL now are exit
callbacks, but for them they make little sense, as the event loop is
exiting then anyway.

0bca283127 man: document sd_event_source_set_floating()
Let's make sure we get back to 100% man page documentation coverage of
our sd-event APIs. We are bad enough at the others, let's get these ones
right at least.

b1de39dec8 man: make separate "Errors" sections subsection of "Return value"
Logically, this is better, because we're describing a subset of possible
return values. Visually this also looks quite good because groff renders
refsect2 much less prominently.

Also rewrap things, add <constant> in various places, fix some typos.

3a54a15760 man: use same header for all files
The "include" files had type "book" for some raeason. I don't think this
is meaningful. Let's just use the same everywhere.

$ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n  "http^gms' man/*.xml

514094f933 man: drop mode line in file headers
This is already included in .dir-locals, so we don't need it
in the files themselves.
