Added nxt_usts2str() to make C strings from nxt_str_t.str-v1
This function is identical to nxt_ustr2str(), except that it takes
a nxt_str_t structure as input, instead of a 'u_char *' and a size.
The documentation of the function:
/*
* SYNOPSIS
* void nxt_usts2str(char dst[restrict .src->length+1],
* const nxt_str_t *restrict src);
*
* ARGUMENTS
* dst Pointer to the first byte of the destination buffer.
* src Pointer to the source Unterminated STring Structure.
*
* DESCRIPTION
* Copy a string from the source nxt_str_t, which may be
* not-NUL-terminated, into a NUL-terminated string in the
* destination buffer.
*
* CAVEATS
* If the destination buffer is not wider than the source buffer
* at least by 1 byte, the behavior is undefined.
*
* EXAMPLES
* nxt_str_t src = nxt_string("0123456789");
* char dst[src.length + 1];
*
* nxt_usts2str(dst, &src);
*
* SEE ALSO
* ustr2str(3), strlcpy(3), strscpy(9)
