[LTP] [PATCH v4] Refactoring dio_append.c using LTP API

[Petr Vorel]

Hi Andrea,

Info for myself: this patch requires "Add io_read_eof in common.h utilities" [1]

I wonder what I'm missing:
./dio_append
tst_test.c:1409: TINFO: Timeout per run is 0h 05m 00s
dio_append.c:69: TINFO: Parent append to file

nit: having the same name as the binary filename is a bit confusing.
(sure will work even run as ./dio_append due use of .needs_tmpdir).

Kind regards,
Petr
