add the --sndfile auto option and check sndfile availability with env['SNDFILE'] instead of is_defined('HAVE_SNDFILE')

use pkg-config to find sndfile (drop explicit LIB_SNDFILE and HAVE_SNDFILE since check_cfg deals with it)

use conf.env['SAMPLERATE'] to determine wether samplerate is available instead of conf.is_defined('HAVE_SAMPLERATE')

jack_transport requires libreadline but not libncurses, so drop the latter.

Reportedly, f28523ff was incomplete.

CCFLAGS isn't honoured at all, the proper name is CFLAGS.

ceilf() is used in netsource.c
Fix for trac ticket #291

Patch by Adam Conrad <adconrad@canonical.com>, taken from Ubuntu's
jackd2 package.

Fixes linkage errors as described in

   http://permalink.gmane.org/gmane.comp.audio.jackit/25841

Thanks to nedko - closes #15

This was supposed to happen in a5eb957b,
but it didn't, so there was still libinprocess.so instead of
inprocess.so.

We need readline for transport.c, but it's built conditionally if
present, so allow the check for readline to fail.

If -DNO_JACK_ERROR is set, jack_error() is replaced by printf().

Since it's a C program, we have to set CFLAGS appropriately.

jackdbus needs explicit index because device reservation code
is shared with jackd and waf cannot autodetect this.

waf complains about missing features in the builder, so let's add some.

For the sake of completeness, here's an example error message:

I don't think anything actually uses the curses library.
