Update documentation dates

Update dates and copyright years in the man pages (didn't happen at
latest release ;-)).
"make distclean" should not get rid of the files distributed in the tarball; text files are deleted with the maintainer-clean target.
Sync' with latest Debian uploads plus few updates toward the next upload.

Fixed tarball name to match version from configure.ac.
More Debian packaging changes, these are more interesting, some highlights:
- multiarch support;
- binary hardening (e.g. stack protector, fortify source);
- updated to use latest dpkg-source format (3.0) and quilt, and got rid of CDBS.

Use binary mode for pipes on all Windows compilers

The fix from 14.4.0 to call popen() with a type argument of "rb"
(binary mode) was active only on MSVC, not on other Windows compilers;
in particular, the distributed Windows binary still used "r" (text
mode), as it is compiled using MinGW.

This fixes tracker item 3602130.
rc3 right before final release
Fix (m)compand modifying their arguments

The compand and mcompand effects modified their arguments while
parsing them (via strtok(), which replaces characters by NUL). This
caused two different problems:

1. For libSoX clients with hardcoded effect arguments given as C
string literals, the program could crash during a call to
sox_effect_options() since those literals may be in write-protected
memory. Ryo Okamoto discovered this bug and provided code to
reproduce it.

2. In SoX, a compand/mcompand effect in a restarted effects chain
could see different arguments the second time it was created. E.g.,
  sox -n -n trim 0 10 compand 0.2,0.5 -6 stats : restart
failed at restart because the compand effect now saw "0.2" instead of
"0.2,0.5" as its first argument, which is a syntax error.

The fix duplicates the affected arguments and uses the copy for
further processing.
