standalone with no ties to internal samba4 functions
Samba4 itself just uses the plain library, compatibility glue is
in events_s4.c only

There are still a few tidyups of old FSF addresses to come (in both s3
and s4). More commits soon.

- if someone adds a timed_event with a zero timeval
we now avoid serval gettimeofday() calls and the
event handler doesn't get the current time when it's
called, instead we also pass a zero timeval
- this also makes sure multiple timed events with a zero timeval
are processed in the order there're added.
the little benchmark shows that processing 2000000 directly timed events
is now much faster, while avoiding syscalls at all!

add support for sa_flags argument to event_add_signal(). These are
passed to sigaction(). Special handling is provided for SA_RESETHAND
(which tells the event system to remove the handler after the signal)
and SA_SIGINFO which allows the siginfo structure to be received per
signal

Jeremy asked for this to allow Samba3 to use the Samba4 events library
see torture/local/event.c for an example

- make it easier to plug in a new events backend
- add simpler 'select' and 'epoll' backends
This is part of the effort to add good AIO support. The events_aio.c
backend is done, but sometimes dies with a SEGV, which is why it isn't
enabled yet.

the events backend can store private flags
- add function to access the gtk event loop ops struct

using other implementations possible. This will be mostly usefull
for client apps which have there own event loop and want to
use our client libs
- add a example plugin for liboop (see http://liboop.org)
NOTE: this just compiles and is completly untested
and is commited only as example
