Summary:                    [patch] Clean valgrind output by suppressing false
errors
Description: 
There are some false errors that are flooding valgrind log. 

Attached small valgrind suppression file that filters out most common
errors. It's supposed to be placed in utils/asterisk.supp but if other dir
is chosen, it should be updated in valgrind.txt

Also updated valgrind.txt so that 
* it doesn't write malloc_debug.txt from stderr (which never ever
contained anything useful).
* --log-fd is used instead of --log-file. This helps to avoid flood with
"Use --log-fd=<number> to select an alternative log fd" messages.

amorsen: regarding log of https://issues.asterisk.org/view.php?id=16038  i
wonder what are your compile flags.
Could You paste output of "core show settings"? 

This dlclose/load_modules should be handled by suppression file, and at
0x47ADA7 should be load_dynamic_module.

lmadsen: i wouldn't call this a patch, it's merely a cleaner output of
debug :)
