Tag various character arrays with NXT_NONSTRING
In Unit we have a number of character arrays which are intentionally not
NUL terminated.
With GCC 15 this
static const char hex[16] = "0123456789ABCDEF";
will trigger a warning like
$ gcc -Wextra -c nonstring.c
nonstring.c: In function ‘hexit’:
nonstring.c:9:37: warning: initializer-string for array of ‘char’ truncates NUL terminator but destination lacks ‘nonstring’ attribute (17 chars into 16 available) [-Wunterminated-string-initialization]
9 | static const char hex[16] = "0123456789ABCDEF";
| ^~~~~~~~~~~~~~~~~~
By adding NXT_NONSTRING like
static const char hex[16] NXT_NONSTRING = "0123456789ABCDEF";
we no longer get the warning.
