But would strlen()'s loop not terminate on the first 0x00 char??  I mean a 
couple dozen cycles here is not something a user's gonna notice, even in a 
tight loop that is processing strings for Asterisk.

Personally I feel this whole ast_strlen_zero macro (it better be a macro or at 
least inline function!) is poor optimization -- does Asterisk really spend so 
much time in strlen() that it was necessary?
