2c78a4f527 tevent: introduce tevent_set_max_debug_level() (default TEVENT_DEBUG_WARNING) 
Allow an application to decide which log levels it wants to get
in the callback function passed to tevent_set_debug().

By default TEVENT_DEBUG_WARNING is the maximal reported level
and TEVENT_DEBUG_TRACE message no longer reach the callback function
by default.

It seems Samba is the only consumer of tevent_set_debug(), so it
should not be a huge problem, as Samba only reports TEVENT_DEBUG_TRACE
message with log level 50 anyway. And future Samba versions will
call tevent_set_max_debug_level() if needed.

Note the change to tevent-0.14.1.sigs will be reverted
with the release of tevent 0.15.0.

683c44a79f tevent: add event trace api 
Adds new tracing API to trace fd, timer, signal and immediate events
on specific trace points: attach, before handler and dettach.

This can be used in combination with the event tag to keep track
of the currently executed event for purpose of debugging.

ac9569b1a6 tevent: add tevent_context_wrapper_create() infrastructure 
This allows to specify wrapper tevent_contexts, which adds the ability
to run functions before and after the event handler functions.

This can be used to implement impersonation hooks
or advanced debugging/profiling hooks.

We'll undo the 0.9.36 ABI change on the 0.9.37 release
at the end of this patchset.

796acbd9ff lib/tevent: Add trace point callback 
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.
