To retain legacy behavior I decided to add an option to control request
termination logic. If request_terminate_timeout_track_finished is set,
then request will be tracked for time limits even after
fastcgi_finish_request was called.

This patch depends on the fix provided in BUG 78469 (otherwise php-fpm
workers listening on named pipes on Windows will be erroneously terminated)
(PR #4636)

Because of user specific webdirs it should be possible to set a
status/ping path like "/~username/status".

Closes GH-4698.

Seems to be very unreliable in CI.

4 seems to be enough to reliably reproduce the issue. Let's see
if this works better in CI.

epoll event backend does not guarantee that child input/output events
are reported before SIGCHILD due to finished worker. While a bunch of
events received by epoll is being processed, child-related structures
may be removed before dispatching of an I/O event for the same child.
The result may be attempt to access to memory region allocated for
another purpose, segfault of the master process, and unavailable web
sites.

Postpone processing of SIGCHILD events till other events in the same
bunch are processed.
