New libsox example6: give explicit output attributes
prevent division by 0 when input signal is entirely non-negative, non-positive, or both
Fix warning about ignored cdecl.

Only need value on prototype; not the implementation.
Switch to gcc's -fstack-protector

_FORTIFY_SOURCE=2 compiles fail with error on newer gccs if
-O is not enabled.  Instead of risking optimization related issues,
switching to gcc -fstack-protect (since 4.1 or 2007) or
-fstack-protector-strong (since 4.9 or 2014).

Redhat/Fedora ships with -fstack-protector for all RPM's and
is switching to -fstack-protector-strong this year so should be
well tested.

cmake could stand to be improved and enable -fstack-protector-strong
for newer compilers.
Default to silent mode for automake

Prevents the compiler warnings from being lost in the noise.

Use 'make V=1' to get older verbose compile output.
osxbuild updates for OSX 10.9 and latest libraries
Update stack-protect logic to work for cygwin

Get ready for 14.4.2rc1 release.
Check for minimum size sphere headers
More checks for invalid MS ADPCM blocks.

If block doesn't exacty match blockAlign then do not allow
number of samples in invalid size block to ever be more than
what WAV header defined as samplesPerBlock.
Switch to rsync when releasing files

Better handles slow VM's.
Distribute real sox.exe and not libtool wrapper.
