Set/get a single callback function to be invoked at various trace
points. Define "before wait" and "after wait" trace points - more
trace points can be added later if required.
CTDB wants this to log long waits and events.

When doing
fd1 = tevent_add_fd(ev, ev, 2, 0, NULL, NULL);
fd2 = tevent_add_fd(ev, ev, 3, 0, NULL, NULL);
TALLOC_FREE(fd2);
fd2 = tevent_add_fd(ev, ev, 1, 0, NULL, NULL);
we end up with select_ev->maxfd==1. This is wrong.
An alternative fix might be to make select_ev->maxfd an unsigned int and make
EVENT_INVALID_MAXFD==UINT_MAX. But in theory we might end up with an fd of
UINT_MAX.
std_event_add_fd() contains exactly the same piece of code, so I'm directly
pushing it.

these are not supposed to be exposed in the library
|
|
They're like directly triggered timed events,
but you can preallocated them and scheduling them
will not fail.

tevent_loop_wait should do the same for all backends.
It should loop as long as we have pending events.
metze
|
|
We also check for signal events directly before and after
the select/epoll calls.
metze
|
|
This makes the logic much simpler for the callers,
and matches the samba3 behavior.
If needed we can add performance tunning for tevent_loop_wait()
later.

Also add tevent_timeval_add() and tevent_timeval_current_ofs()
to help not depending on lub/util/time.c for things that just need tevent

This fixes crash bugs... I forgot to commit and squash
this to commit e45ed828d042acca09cb1ed5b6dd7a24eb5e7ffd

TEVENT_FD_AUTOCLOSE adds a dependency to SOCKET_WRAPPER,
which is bad. Callers should use tevent_fd_set_close_fn() now.

Let callers specify a close function
as an alternative to TEVENT_FD_AUTOCLOSE.

And related changes, but we keep compat macros

And fix the callers and there init functions.

We have compat macros to keep the callers happy.
