Hello Guys,

The 1st patch adds one ublk utility and one entry test.

The 2nd patch adds test over file backed ublk.

The 3rd patch adds test for ublk zero copy.

How to run:

- make install
- make headers_install INSTALL_HDR_PATH=/usr # in case UAPI is changed
- reboot
- make -C tools/testing/selftests TARGETS=ublk run_test

Thanks,

V2:
- fix one sqe allocation bug, so ublk zero copy with io_link can pass
- dump log in case of error
- add one more test for mkfs/mount on zero copy
