This patch adds support for running Asterisk under Valgrind (say: Val-Grinned) to check for all sorts of nasty runtime bugs.  This started off with a post to asterisk-dev list by nitesh.bansal at gmail.com, and he wrote and contributed the initial version.  So if you find this useful, be sure to thank him.  Then I made extensive changes and additions, so if the code stinks, blame me.

The following has been done:

- Check runtests.py arguments for --valgrind and --valgrind-gensupp flags, pass via environ to TestCase.py
- Note previously existing instances of ast# logs to insure we only process new log/xml files
- Increase reactor timeout by x5 when valgrind enabled
- Patch to reactor_stop() to insure it does even when exceptions occur in deferred stack
- Add valgrind with correct arguments into executable path
- After run, check valgrind.xml for errors, parse and condense them into something more managable
- If -gensup mode enabled, write suppressions to logs/(test)/ast#/valgrind.supp that can be added (manually)
- A default valgrind.supp "suppressions" file is in configs/ to prevent complaints about known unfixables


- valgrind can be triggered by argument to runtests.py, export VALGRIND=true, or in test-config.yaml
- configs/valgrind.supp will be used if found, but tests/(test)/configs/valgrind.supp will take precedence
- valgrind-gensupp mode will create example suppressions file, during which no suppressions occur

Tested on 64bit and 32bit CentOS, including low cpu power conditions.  Some sporadic timing issues affecting AMI/twisted operation have been seen and will be corrected.
