Inject random corruption on UBIFS image by writting random data on
kinds of mtd devices (eg. nand, nor), check the consistency of UBIFS
after fsck.
This testcase simulates random bad UBIFS image caused by hardware
exceptions(eg. ecc uncorrectable, unwritten), and makes sure that
fsck.ubifs could make UBIFS be consistent after repairing UBIFS
image.

Inject powercut while doing fsstress on mounted UBIFS, check the
consistency of UBIFS after fsck.
This testscase mainly makes sure that fsck.ubifs can make UBIFS
image be consistent in common stress cases and powercut cases.

Inject memory/io fault while doing fsck for corrupted UBIFS images.
This testcase mainly checks whether fsck.ubifs has problems (eg.
UAF, null-ptr-def, etc.) in random error paths. Besides, it provides
a similar way to simulate powercut during fsck, and checks whether
the fsck.ubifs can fix an UBIFS image after many rounds interrupted
by kinds of errors.

Inject powercut while doing fsstress on mounted UBIFS for kinds of
flashes (eg. nand, nor).
This testcase mainly makes sure that fsck.ubifs can make UBIFS image
be consistent on different flashes (eg. nand, nor). Because the
min_io_size of nor flash is 1, the UBIFS image on nor flash will be
different from nand flash after doing powercut, so we need make sure
fsck.ubifs can handle these two types of flash.

Do fsstress and fsck, check whether there are any files(and their data)
are lost after fsck. This testcase mainly checks whether fsck.ubifs could
corrupt the filesystem content in common case.

Authenticated UBIFS image is not supported in fsck, add testcase
to check that.

This is a preparation for adding testcases for fsck.ubifs and
mkfs.ubifs. Add some common functions, for example: powercut,
load_mtdram, mount_ubifs, encryption operations, etc.
