[LTP] [PATCH v3 0/6] add open/openat + O_TMPFILE tests

[Alexey Kodanev]

v3:
* squash last patch into the previous,
* open: make use of SAFE_OPEN during the test,
* openat: add tst_openat_tmp(int mode),
* remove test_dir, use ".",
* use tst_brkm(TFAIL, ...) for test assertions,
* strncmp() -> memcpy(),
* more verbose test-case's TPASS message.

v2:
* move dir_not_empty() -> tst_dir_is_empty() to a library,
* add SAFE_LINKAT, SAFE_READLINK macros,
* move O_TMPFILE definition to lapi/fcntl.h
* use relative path for test_dir,
* enable len_strict in SAFE_WRITE,
* set constant buffer size.
