Summary
-------

This is the first of many parts of the overall goal of improving Asterisk APIs. This adds a UUID API to Asterisk, eventually to be used as a method of uniquely identifying channels and potentially other objects.

The implementation here uses libuuid, which is packaged by all major Linux distributions. The API is basically a wrapper around libuuid's API, but it hides all implementation details in case we want to switch out libraries at some point.

Licensing for libuuid is a bit confusing. On one hand, this online man page (http://linux.die.net/man/3/libuuid) claims that the library is distributed under the LGPL version 2. However, when I downloaded the source for the library on my machine, the code had the 3-clause BSD license printed in the source. In either case, I believe use of external library is license-compatible with Asterisk.

Regarding specific implementation decisions, I think comments in the code should explain why I chose to do things certain ways. Please let me know if anything should be done differently or if you have ideas for tests beyond what I have already included.

I have no idea what is up with the changes listed in autoconfig.h.in. Those changes showed up when I ran the bootstrap.sh script after changing configure.ac. 


This addresses bug ASTERISK-20725.

Testing
-------

I have included a set of unit tests that exercise all the APIs. They pass when run locally.


Thanks,

Mark
