[Asterisk-Dev] [RFC] strncpy -> ast_copy_string

[James Golovich]

I haven't been following this too closely, but I know about
ast_strlen_zero since I did that.  Most uses of strlen in asterisk were to
check if a string was or wasn't length 0, but there still are a ton of
uses that really need to know the length.
