[Asterisk-code-review] strings.h: ast_str_to_upper() and _to_lower() are not pure. (asterisk[master])

[Joshua Colp]

Joshua Colp has submitted this change. ( https://gerrit.asterisk.org/c/asterisk/+/15578 )

Change subject: strings.h: ast_str_to_upper() and _to_lower() are not pure.
......................................................................

strings.h: ast_str_to_upper() and _to_lower() are not pure.

Because they modify their argument they are not pure functions and
should not be marked as such, otherwise the compiler may optimize
them away.
