dd46861282 libbb: Converted safe_read to safe_write format
Changed safe_read to be symmetrical to safe_write, it shall
never return EINTR because it calls read multiple times,
the error is considered transient.

0ef64bdb40 *: make GNU licensing statement forms more regular
This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

ab19ede655 tidy up O_NONBLOCK usage. use libbb functions in stty.
Added O_RDONLY where improves readability. Note: O_RDONLY == 0,
so it is there even if not specified.
