      On graceless shutdown or restart, send AP_SIG_GRACEFUL to all worker · 14774214

      threads so that any that are polling on Keep-Alive connections will
wake up and exit promptly.  Otherwise, on Linux, they wait until
poll()'s timeout interval completes, which is often too long for
the parent process; the parent issues SIGKILL before the child's main
thread manages to re-join all the worker threads.  PR 38737.

On Solaris, by contrast, the close_worker_sockets() function
successfully alerts all worker threads that they should exit quickly.
On Linux, this side-effect of one thread closing another's socket
doesn't occur; see:

http://bugme.osdl.org/show_bug.cgi?id=546

Also, expand on the placeholder in CHANGES regarding previous
cleanups to scoreboard.c and scoreboard.h in r404848 and r404849.

      Make the worker and event MPMs not touch the scoreboard when · 053c9598

      handling a fork() failure.  The previous behaviour appears to have
been inherited from the prefork MPM, where is it appropriate.

The prefork MPM sets thread_limit to 1 and therefore each
child process has a single worker_score structure in the scoreboard's
array, i.e., ap_scoreboard_image->servers[slot][0].  In make_child(),
it sets this structure's status to SERVER_STARTING, and then does
a fork(); if the fork() fails, it resets the status to SERVER_DEAD.

The worker and event MPMs, by constrast, obviously use multiple
worker_score structures per child process.  They may also be
in use by worker threads from a previous generation at any particular
moment.  Therefore make_child() and the parent process in general
doesn't normally update them; make_child() doesn't set them all
to SERVER_STARTING before doing fork(), for example.

So, make_child() shouldn't set them to SERVER_DEAD if fork()
fails (and even if it should, it certainly shouldn't be just
updating the first one).
