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: --log-fd means which of file descriptors valgrind will use for
output.

I'm not sure, why using --log-file creates lot of log messages saying to
use --log-fd, but using --log-fd has no real disadvantages over --log-file.
The only disadvantage would be that asterisk wis able to use one less file
descriptor, but it donesn't use more than 3 anyway.

Actually, You can control it just like any file descriptor, if You want to
append next valgrind log to previous one, just use:

valgrind --suppressions=/usr/src/asterisk/utils/asterisk.supp --log-fd=9
asterisk -vvvvcg 9>>valgrind.txt

That has two >> symbols instead of one >.
