* ex.
* - parse buf: read chunk full [aaaaa\nbbbb] (pos = 0)
* - get line: returns "aaaaa\0" (next_pos points to first 'b')
* - get line: from 'b', but reaches buf end before \n or EOF: must readjust
* - parse buf: move chunk part [bbbb*******] ('b' to beginning, * is garbage)
* - parse buf: read chunk part [bbbbbb\ncc_] (reaches EOF)
* - get line: returns "bbbbbb\0" (pos points to first c)
* - get line: returns "cc\0"
* - get line: returns NULL (reached EOF, no more bytes)
* - (there is an implicit \0 reserved in buf)

* - get line: reaches buf end, but didn't reach EOF nor \n: error, can't store line
