Fix compiler warning about unused label on non Win32

- separated two causes of an error
- gave the win32 "lost signal" case a more descriptive message

- moved platform dependend code into scope its respective #ifdef
- killed one useless 'goto' with great pleasure
- introduced duplicate code to preserve behavior (fallthrough case)

Changed inconsistent lineendings to UNIX format

- used dos2unix
- this also cleaned some whitespaces

Setting the JACK_NO_AUDIO_RESERVATION environment variable let one skip the
audio reservation bits.
The main use case is a system-wide jackd promiscuous instance launched at boot
time. In such a case no session bus is available, and reservation doesn't
really makes sense anyway.

including S24_LE/BE formats to linux alsa driver

fix bug on building under path with whitespaces

- wrapping the path strings in quotes prevents interpretation as multiple files
  or paths if there are whitespaces in the path.
