the check for NEON so far only checked if -mfpu=neon is understood by the compiler,
however, this is not enough:
(i) #include <arm_neon.h> should be checked
(ii) -mfpu=neon must be passed before CFLAGS because eventually the per-library CFLAGS
for NEON code in src/Makefile.am are passed to the compiler before the global CFLAGS
in case the build environment passes CFLAGS to configure and we try to set conflicting
CFLAGS option, the former take precedence; CFLAGS cannot be overridden
this does not fix

but at least makes the build fail in configure (and not while compiling stuff)
and gives better diagnostics

The mixer paths are not available in ${builddir} - we need to look in
${srcdir}. This should fix running an in-tree build without make install
as well as alsa-mixer-path-test in make distcheck.
Since the most straightforward way to define PA_SRCDIR was in
Makefile.am, I'm moving PA_BUILDDIR there as well for consistency.
The previous AAC pass-through patch (commit: 53807e4a) introduced
a new encoding format type: PA_ENCODING_MPEG2_AAC_IEC61937,
which is mostly used in pa_format_info, but forgot to increment the
protocol version number. The version needs to be incremented, because
clients need some way of checking whether the server supports the new
encoding.

final:
* includes some minor style fixes and build-time changes to allow
building a single binary for neon and non-neon systems
v4:
* fix for sample length < 4
v3:
* convert from intrinsics to inline assembly
v2:
* load and store data with vld1/vld1q and vst1/vst1q, resp., to work
around alignment issues of compiler-generated vldmia instruction
* remove redundant check for NEON flags

The GNOME-OSTree build system currently creates chroots and bind
mounts to the source tree outside the root; this means that we can't
necessarily run git inside the root, because in the case of git
submodules, the .git repository will point to outside root.
Also, error out fatally if we fail to determine the version; it
makes no sense to put UNKNOWN in e.g. the pkg-config files
since this will just cause errors later on.
Keeping the SBC check separate means we can keep the SBC_LIBS/CFLAGS
separate, which is cleaner. Thanks to Jan Steffens for pointing out that
this was broken (SBC_* wasn't actually changed to match the configure
change).
This reverts commit da5078e5c7.
This includes updating the native protocol and the client API.
A new command was added to allow setting the latency offset.
Also the card list command now shows the latency offset if there
are ports available.
Update protocol to 27.
ConsoleKit has been deprecated and replaced by systemd's logind daemon,
hence provide the same functionality of module-console-kit in
module-systemd-login. This also makes sure that the CK module becomes a
NOP if the system is booted with systemd, resp. that the systemd module
becomes a NOP if the system is booted without systemd, thus being nice
to OSes such as Debian which want to support multiple init systems.
A part of Xen's paravirtualized audio driver has been developed as a
pulseaudio module. This module acts as a tunnel over Xen's shared memory
mechanism and allows a domU guest to send audio data to a dom0 backend.

For volume control UIs to be able to show ports in inactive profiles,
expose all ports together with the card info. This includes updating
the protocol and the client API to show the connection between ports
and for which profiles the ports are relevant.
Update protocol to 26.

We can't call IT_PROG_INTLTOOL because it requires intltool even with
--disable-nls, but it provides USE_NLS which is required for the po/
build. This might take a while to get fixed upstream, so working around
this in our build system for now.
configure doesn't provide an abs_top_srcdir early enough, so we just use
srcdir for that. There was also a problem with the path we were setting
in VERSIONING_LDFLAGS that is fixed now.
makes the Adrian echo canceller implementation optional at compile time
this patch supersedes an earlier patch proposal and addresses the following
comments:
* separate patch from speex dependency rework (Arun)
* check that at least one EC implementation is available (Arun)
* properly align yes/no in configure summary for Adrian (Frederic)
make speex library dependency optional, this affects the resampler
and the echo canceller module
this patch supersedes an earlier patch proposal and addresses the following
comments:
* fix order of pa_echo_canceller_method_t enum and ec_table (Frederic)
* the default resampler is speex if available as before, otherwise ffmpeg (Arun)
* does not touch the Adrian EC implementation (see separate patch) (Arun)
