Because debian does not run with the freebsd libc, but rather uses the
GNU one, it chose to not define __FreeBSD__, but rather __FreeBSD_kernel__.
Use the alternative when the functionality tested is for kernel
features, and keep the __FreeBSD__ one when using freebsd libc
headers.
If this patch is applied, debian could drop all the current patches when
importing 6.0 :)

the macro PA_UNUSED may be used to suppress a warning when a variable
is not used, or assigned and never used; this typically happens
when the only use of the variable is within an assert() that can
be optimized away (i.e. with NDEBUG set)
has an effect with GCC only

This adds support to module-native-protocol-unix to take over already
listening sockets passed in via socket activation (e.g. from systemd)
Most of the code is isolated to socket-server but some cleanup code also
had to be tweaked to ensure we do not overzealously close open fds.
We currently use the term SYSTEMD when referring to libsystemd-login
and JOURNAL when referring to libsystemd-journal.
I will be shortly adding support for libsystemd-daemon and in
preparation I figured it would be a good idea to clarify the names
used currently before adding another!
We will just ignore the memblock if this happens. We already have
a check for this in the client library, so this one is just for
security reasons.

Since we don't allow lengths that are not frame aligned,
it does not make sense to allow indices that are not frame aligned
either.
Also, allowing such a thing to be added causes the daemon to crash
later instead (see https://bugs.freedesktop.org/show_bug.cgi?id=77595 ).
Also drop _se from assert (there is no side effect).

Calling the callback while setting it up can make things
complicated for clients, as the callback can do arbitrarily
things.
In this case, a protocol error caused the srbchannel to be
owned by both the pstream and the native connection.
Now the read callback is deferred, making sure the callback
is called from a cleaner context where errors are handled
appropriately.

The remapper and channel mixing code have (faster) specialized and (slower)
generic code certain code path. The flag force_generic_code can be set to
force the generic code path which is useful for testing. Code duplication
(such as in mix-special-test) can be avoided, cleanup patches follow.

Usually, PA will use the PULSE_SERVER X11 property instead of using XDG_RUNTIME_DIR,
so this environment variable does not matter.
If this property is not available, or if one is using the pacmd cli protocol,
the client will go ahead and call pa_make_secure_dir on XDG_RUNTIME_DIR/pulse.
This will either fail (if you're another regular user), or succeed (if you're root).
Both scenarios are bad - failing will cause the connection to fail, and succeeding
is even worse, as it can cause *other* connections to fail (as the directory
ownership has changed).
Instead fail and complain loudly.

building PA with -O0 leads to test failure in mix-test on i386
issue reported by Felipe, see
http://lists.freedesktop.org/archives/pulseaudio-discuss/2014-August/021406.html
the problem is the value 0xbeffbd7f: when byte-swapped it becomes 0x7fbdffbe and according
to IEEE-754 represents a signalling NaN (starting with s111 1111 10, see http://en.wikipedia.org/wiki/NaN)
when this value is assigned to a floating point register, it becomes 0x7ffdffbe, representing
a quiet NaN (starting with s111 1111 11) -- a signalling NaN is turned into a quiet NaN!
so PA_FLOAT32_SWAP(PA_FLOAT32_SWAP(x)) != x for certain values, uhuh!
the following test code can be used; due to volatile, it will always demonstrate the issue;
without volatile, it depends on the optimization level (i386, 32-bit, gcc 4.9):
// snip
static inline float PA_FLOAT32_SWAP(float x) {
union {
float f;
uint32_t u;
} t;
t.f = x;
t.u = bswap_32(t.u);
return t.f;
}
int main() {
unsigned x = 0xbeffbd7f;
volatile float f = PA_FLOAT32_SWAP(*(float *)&x);
printf("%08x %08x %08x %f\n", 0xbeffbd7f, *(unsigned *)&f, bswap_32(*(unsigned *)&f), f);
}
// snip
the problem goes away with optimization when no temporary floating point registers are used
the proposed solution is to avoid passing swapped floating point data in a
float; this is done with new functions PA_READ_FLOAT32RE() and PA_WRITE_FLOAT32RE()
which use uint32_t to dereference a pointer and byte-swap the data, hence no temporary
float variable is used
also delete PA_FLOAT32_TO_LE()/_BE(), not used

Since we don't have "limited" clients, a client that authenticates
correctly is automatically authorized. However, it's the authentication
that can go wrong, rather than the authorization.

This makes it easy to log a message every time the reference ratio
changes. I also need to add a hook for reference ratio changes, but
that need will go away if the stream relative volume controls will be
created by the core in the future.
