## Description

`zt2str` converts zero terminated string to str_t. It doesn't copy data - both strings use the same buffer!

`is_str_empty` returns 1 if given string is empty (NULL pointer or length < 1 or NULL pointer to string data)

`zt_strdup` duplicates given zero terminated string to another zero terminated string using cds_malloc function

`str_prefix` returns 0 if string `b` is prefix of `a`, nonzero otherwise (deprecated)

`str_strchr` searches for given character. It returns pointer to it in the string or NULL if not found.
