added dbus support
removed cruft from inherited from ladspa module and improved clarity
switched dsp processing to reference implementation until project is more mature
tsched=0 seems to help with the micro-dropouts/crackling! oh my!

Get rid of the liboil dependency and reimplement the liboil functions with an
equivalent C implementation. Note that most of these functions are deprecated in
liboil and that none of them had any optimisations. We can further specialize
our handrolled versions for some extra speedups.
This adds module-hal-detect-compat.c which when enabled will be compiled
into a module module-hal-detect which simply loads module-udev-detect.
The purpose of this is to allow easy upgrading without breaking
default.pa. Distributions are recommended to enable this to easy
upgrades from HAL versions of PA to udev versions.
Since Fedora does not enable OSS output support at all, but still uses
padsp, and in Gentoo we could also make use of padsp without OSS output
support, split the two things in two parameters, although they both check
for sys/soundcard.h once.
On non-GNU, non-Sun linkers, the -z option is often not understood; make
sure that the -z nodelete option is usable before making use of it.
Unbreaks build on Mac OS X.
Instead of trying to re-execute pulseaudio itself with LD_BIND_NOW set,
just find the correct flag for the linker to request immediate bindings
(all ELF files support that option), and use that when linking the daemon.
Reduce the amount of compiled and executed code as well.
On FreeBSD the backtrace() function as well as the execinfo.h headers are
provided by libexecinfo (an optional package). PulseAudio “automagically”
identifies execinfo.h and proceeds to use it, but then will fail to link
against the library.
Thanks to Alexis Ballier for reporting.
The error message was way too generic, as it was very possible that libltdl
_is_ in the system but is not found because too old. Disambiguate this by
explicitly stating that the version 2 of the library is not found.
When we're unconditionally looking for a function, or an header file,
without particular libraries set, or with found/not-found conditional code,
we can save ~1K lines in the final configure script by using the _ONCE
variant.
This makes sure that for each header of function, the check is done exactly
once and never more, reducing the amount of code that has to be generated
and executed.
Instead of checking for GNU ld presence, check if the linker knows about
the -version-script flag. Non-GNU linkers may export the same interface.
It also allows to check for alternative syntax for symbol versioning.
