[LTP] [PATCH v2 0/7] Rewrite fs stream testing suite

[Andrea Cervesato]

All tests are now using the new LTP API. The stream05 has been deleted
because I think it was a bit messy and it didn't have a proper testing
focus. I replaced it with a new test that is just verifying that fd
returned by `fileno()` can be used for basic operations on fd.

Changes in v3:
- fix stream01 buffer size
- add TST_EXP_PASS_PTR_NULL() macro

Changes in v2:
- add SAFE_FFLUSH() macro
- remove cleanup_fn from SAFE_* macros
- stream01: use a double buffer to write data inside file
- stream02: check if stream is NULL after fopen()
- stream05: use SAFE_FFLUSH()
- stream05: don't overengineer SAFE_FILENO() with TST_EXP_FD()
