Converting these macros to functions declared static inline allow the
C type-checker to work and avoid warnings about unused expression
values.  These warnings break the build with clang.

This avoid warnings about expressions with unused values.  These
warnings break the build with clang.

An optimizing compiler should still inline these calls.  If that turns
out not to happen on some platform, we could rename the functions used
internally and declare them static inline.

These calls were zeroing only a pointer's worth of memory rather than
the actual size of the objects.

clang warns:

  warning: returning 'const char *' from a function with result type
    'char *' discards qualifiers [-Wincompatible-pointer-types]

The implementation clears the context / state data from memory when it
is finished with it.  Prior to this commit, however, it was actually
only clearing the first 4 bytes on x86 or 8 bytes on x86_64.

clang warns:

  warning: argument to 'sizeof' in 'memset' call is the same
  expression as the destination; did you mean to dereference it?
      [-Wsizeof-pointer-memaccess]

On some compilers this fixes the build.

gcc reports:

  error: format not a string literal and no format arguments

clang reports:

  error: format string is not a string literal (potentially insecure) [-Werror,-Wformat-security]

This causes a warning that breaks the build with clang.

This adds the .version file to nightlies produced with debian/util.sh.

Debian nightlies created with debian/util.sh now have the version set
in the same format as Makefile.am produces.  Unlike Makefile.am,
however, we show the orig packaging date rather than the date of the
latest commit, as the latter could legitimately regress and we need
this to always increment.

When we're terminating ZRTP to an IVR or to a leg which is not
ZRTP-capable, there's no way for us to make an intelligent decision
about whether this flag should be set.  For a client to consider the
SAS as verified, however, both sides need to set this flag.  By always
setting this flag on our side, we leave the decision completely in the
hands of the client where we hope there is a careful human.

add video support to lib/mod.dingaling this needs testing, google voice won't work with video calls so disable video codecs if you use that

FS-4319 --resolve portaudio not always moving the active call to the top of its internal list (invalid ringing)

This reverts commit 28fd1f97.

this needs to be fixed a different way
