8ea355e52c audioringbuffer: Avoid overflows of segment done counter
This counter is incremented once for every segment, meaning it would
e.g. overflow after 24 days when using 1ms segments. Once that happens,
completely wrong positions are reported and invalid memory is handed out
for writing/reading the next segments.

As the affected variables are unfortunately part of the public API of
the struct, a second set of variables is added together with accessor
functions and both variables are kept in sync for backwards
compatibility.

All existing users of the two variables are moved to the new ones but
external code might still run into the overflow.

This also slightly breaks API as external code updating the variables
will have no effect anymore but the only known user of this is
pulsesink.

82b10e57b0 pulsesink: Re-enable emission of stream status messages
This was disabled almost 10 years ago because we were missing libpulse API to
avoid a deadlock. That was fixed quite a long time ago, so let's enable this
again. The defer counter becomes an atomic, as we no longer have a threaded
mainloop lock protecting it.

bb2c5981fe pulse: Change bitfield booleans to normal gbooleans
Assigning TRUE (1) to a signed 1 bit integer will cause truncation
from 1 to -1 because the only non-zero value that can be stored is -1
due to how two's-complement works.

As this is a proper GObject let's not bother with all this and simply
use a normal gboolean instead.

../subprojects/gst-plugins-good/ext/pulse/pulsesink.c:1490:19: warning: implicit truncation from 'int' to a one-bit
        wide bit-field changes value from 1 to -1 [-Wsingle-bit-bitfield-constant-conversion]
  pbuf->in_commit = TRUE;

6a2a5fd44c pulsesink: Fix occasional period of silence on resume
According to comment in gst_pulsering_stream_latency_cb, latency updates
happen every 100 ms. The code in gst_pulsering_stream_latency_cb does
not care about the actual state of the ringbuffer, pbuf->acquired or
not.
Thus, every 100 ms the ringbuf->segdone may be set, even though the
object itself might be in 'destroyed' state. On next
gst_pulseringbuffer_acquire the segdone is not touched, so playback may
resume with invalid/wrong segdone value. This finally leads to a period
of silence playing after resuming the pipeline.

The problem was found on 'not-yet-released'-hardware and so far was not
reproducible on desktop computer.

Removing the callback as long as the ringbuffer is not in 'acquired'
state solves the problem reliably on the hardware device that the issue
was detected on.

b99ecc78ca Replace gst-i18n-*.h with gi18n-lib.h
GLib guarantees libintl is always present, using proxy-libintl as
last resort. There is no need to mock gettex API any more.

This fix static build on Windows because G_INTL_STATIC_COMPILATION must
be defined before including libintl.h, and glib does it for us as part
as including glib.h.
