New repository: minisip_autobuild

[Werner Dittmann]

All,

after all I managed to have the new ZRTP library up and running.
The most problems I had was with the configure stuff and the
support of build.pl script.

After countless bootstrap/configure/compile runs it finally worked
as expected. If you have any problems with libzrtpcpp integration
please just drop a line. During the next days I check-in some fixes
that are necessary for interoperability with the latest Zfone Beta.

There is a new directory: libzrtpcpp that is parallel to the other
library directories. It contains the generic ZRTP code and header
files as well as the ZRTP specific cryptographic code.

The libminisip has a zrtp directory as well, this holds the
ZrtpHostBridgeMinisip class. This class is the minisip depended part
of ZRTP and glues the generic part to minisip. Some files inside
libminisip (e.g. media*) have #ifdef ZRTP_SUPPORT, but this didn't
change with respect to the previous solution.

As usual you may switch on the ZRTP support in the build.conf or
build.local files.

Maybe (just to be on the bright side of life :-)  ) you may perform
a complete bootstrap for minisip because build.conf changed and
contains the libzrtpcpp as a new target and libzrtpcpp is a new
library for minisip.

Regards,
Werner
