0edcf725bc win32: Fix WSAStartup issues
WSAStartup was not being called for pacat and pactl built with meson,
causing them to fail in pa_mainloop_new with "cannot create wakeup
pipe". This issue also affects other applications linking to libpulse
other than the pulseaudio daemon, which calls WSAStartup itself.

When built with autotools, WSAStartup would have been called in
DllMain, which is recommended against by the documentation [1].

To fix these issues, the WSAStartup/WSACleanup calls can be moved
into pa_mainloop_new/pa_mainloop_free.

e6b3edd3c1 Revert "mainloop: fix timeout assignment in pa_mainloop_prepare"
This reverts commit 6b1719d0ed, as it
inadvertently broke the semantics of timeout in the API.

6b1719d0ed mainloop: fix timeout assignment in pa_mainloop_prepare
The function calculates the correct timeout (in microseconds) to assign 
in the `u` variable, but then assigns `m->prepared_timeout` the value   
of the `timeout` argument (in milliseconds).

fe346caded mainloop: avoid race-y double wakeup status
Having an extra variable that tracks the wakeup status introduces a
race where the variable is set but the data has yet to propagate from
the write end of the pipe to the read end. When this happens the
system goes into a tight loop as select() always returns immediately.

68156d3f79 mainloop, glib-mainloop: time_restart could cause incorrect event ordering
This fixes a bug where calling time_restart can leave the current event
in the cache, even though the restart scheduled the event in the future.
This would cause the event to get executed more frequently than it should.

97da92d894 Whitespace cleanup: Remove all multiple newlines
This patch removes all occurrences of double and triple
newlines.

Command used for this:
find .  -type d \( -name ffmpeg \) -prune -o \
        -regex '\(.*\.[hc]\|.*\.cc\)' \
        -a -not -name 'adrian-aec.*' -a -not \
        -name reserve.c -a -not -name 'rtkit.*' \
        -exec sed -i -e '/^$/{N;s/^\n$//}' {} \;

Two passes were needed to remove triple newlines.
The excluded files are mirrored files from external sources.

872f56dc7e mainloop: Don't care about the mainloop state variable when waking up the mainloop.
If the mainloop is just about to enter polling, but m->state
is not POLLING yet when some other thread calls
pa_mainloop_wakeup(), the mainloop will not be woken up.
It's safe to write to the wakeup pipe at any time, so let's
just remove the check.

7e344b5ff0 core: Proper poll() emulation to fix pacat and friends on Windows
Currently, Windows versions of pacat and friends fail because the current
poll emulation is not sufficient (it only works for socket fds).

Luckily Gnulib has a much better emulation that seems to work good enough.
The implementation has been largely copied (except a few bug fix
regarding timeout handling, to be pushed upstream) and works on pipes
and files as well. The copy has been obtained through their gnulib-tool utility,
which gives a LGPLv2.1+ licensed file.

This fixes the "Assertion (!e->dead) failed" error coming and lets pacat
and friends stream happily to/from a server (I didn't actually test parec).

b599d3c836 Fix pa_rtclock_from_wallclock
The HAVE_CLOCK_GETTIME macro protects timespec and related functions, nothing of which is used in
pa_rtclock_from_wallclock.  And silently just not converting was not the proper solution anyway.

Also add an assert in pulse/mainloop.c to report the integer overflow that was triggered by the wrong
pa_rtclock_from_wallclock.  Without the assert, debugging was painful.

4f1d4044f8 Use <pulsecore/socket.h> instead of <sys/socket.h>
The check whether POSIX socket.h or WIN32 winsock2.h must be included can be
made centrally.  The downside is that some functionality of e.g. arpa/inet.h is
also implemented in winsock.h, so that some files that don't use socket
functions, but do use inet.h functions, must also include pulsecore/socket.h.
(as well as arpa/inet.h)

17d34462ea poll() is totally broken on Mac OS X
Even on 10.5.8, poll() does not do the right thing. Haven't checked on
newer versions. Hence, wrap all occurences of poll() to pa_poll and
emulate that call with select() on OSX. This is totally embarassing.

23a294c97e Correctly deal with events in the past in calc_next_timeout
pa_usec_t is unsigned, thus it will always be >= 0
This makes gstreamer pulse mixer work again

This fixes a gstreamer mixer regression, when it can't control the volume,
after few changes.

0955e3d45b Base mainloop on pa_rtclock_now()
Move the mainloop to monotonic based time events.

Introduces 4 helper functions:
pa_{context,core}_rttime_{new,restart}(), that fill correctly a
timeval with the rtclock flag set if the mainloop supports it.

Both mainloop-test and mainloop-test-glib works with rt and timeval
based time events. PulseAudio and clients should be fully functional.

This patch has received several iterations, and this one as been
largely untested.
