Add some tools for testing ext4 performance and resiliency.
rand_emmc_perf is a simple test to test random read/write performance
of emmc chips. android_emmc_perf_tests is a script that runs on
the host that uses rand_emmc_perf to test the emmc performance on
a device.
corrupt_gdt_free_blocks is used to corrupt a filesystem so the kernel
trips over it at runtime and panics, thus testing kernel's ability to
mark the filesystem as needing to be fixed.
set_ext4_err_bit sets the error bit in the superblock so e2fsck will
trigger a full check next boot.
corrupt_gdt_free_blocks and set_ext4_err_bit are only built for
userdebug and eng builds. rand_emmc_perf is marked optional, and
not included in any build by default.
