Aurelien DARRAGON f71e0645c1 MEDIUM: server: split srv_update_status() in two functions 
Considering that srv_update_status() is now synchronous again since
3ff577e1 ("MAJOR: server: make server state changes synchronous again"),
and that we can easily identify if the update is from an operational
or administrative context thanks to "MINOR: server: pass adm and op cause
to srv_update_status()".

And given that administrative and operational updates cannot be cumulated
(since srv_update_status() is called synchronously and independently for
admin updates and state/operational updates, and the function directly
consumes the changes).

We split srv_update_status() in 2 distinct parts:

Either <type> is 0, meaning the update is an operational update which
is handled by directly looking at cur_state and next_state to apply the
proper transition.
Also, the check to prevent operational state from being applied
if MAINT admin flag is set is no longer needed given that the calling
functions already ensure this (ie: srv_set_{running,stopping,stopped)

Or <type> is 1, meaning the update is an administrative update, where
cur_admin and next_admin are evaluated to apply the proper transition and
deduct the resulting server state (next_state is updated implicitly).

Once this is done, both operations share a common code path in
srv_update_status() to update proxy and servers stats if required.

Thanks to this change, the function's behavior is much more predictable,
it is not an all-in-one function anymore. Either we apply an operational
change, else it is an administrative change. That's it, we cannot mix
the 2 since both code paths are now properly separated.

  - INSTALL for instructions on how to build and install HAProxy
  - BRANCHES to understand the project's life cycle and what version to use
  - LICENSE for the project's license
  - CONTRIBUTING for the process to follow to submit contributions

The more detailed documentation is located into the doc/ directory :

  - doc/intro.txt for a quick introduction on HAProxy
  - doc/configuration.txt for the configuration's reference manual
