Requesting Get-Values via FCGI caused an "endless" loop over the last requested parameter and ended with an invalid response. this patch solves this loop bug.

The availability of entity loading is stored in a module global which
previously was only initialized in the GINIT constructor. This had the
effect that disabling the entity loader in one request caused
subsequent requests hitting the same Apache child process to also have
the loader disabled.
With this change the loader is explicitely enabled in the request init
phase.
Loop variables need to be freed for both "break" and "continue".
I'm adding the test to Zend/ because it's good to have a test for
this even without opcache.
This replaces the GUI element used for execution timeout handling
on Windows. Instead a timer queue technique is used, which is indeed
a thread pool. A timer queue timer is a lightweight object handled
but that thread pool and the timer thread spends most of the time
sleeping and waiting for an alert.
Please note also that this introduces neither binary nor source
breach. The custom timeout thread functions are deleted, however
they was not exported throug DLL, so couldn't be used by any
external code. As well they couldn't be used anywhere in the core
except in executor api, because those custom timeout thread
functions they used to operate on static variables which would
be overwritten (and that would blow).
So instead a relatively modern technique is used for the timeout
handling. It's still not perfect because the executor still has to
check EX(timed_out). This can be a topic for an improvement in
master. But brobably can be tricky as currently it seems to be not
possible to signal an individual thread. Also note another issue
that static variables aren't thread safe, but the current timer
implementation is.
