Summary:                    Memory leak in channel variables
Description: 
I detected the leak on Asterisk 1.4.21.2. I reproduced the bug easily on
the SVN trunk version. 

After 5000 calls, Asterisk is using more than 500Mb. 

I recompiled with MALLOC_DEBUG (and DONT_OPTIMIZE), and after around 500
calls I found :

661364 bytes in 6321 allocations in file 'config.c'
(numbers increase with calls).

That was the only abnormal allocation (and the only increasing).

All 'config.c' allocations are :

XX bytes allocated in ast_variable_new at line 240 of config.c
(appeared a lot of times with different values).

I added debug to config.c to know which variable was concerned. The only
variables I saw was the variables I set in call files (outgoing calls).
