* changes:
trusty: fuzz: dump trusty kernel logs on crash
trusty: Add corpus for gatekeeper fuzzer
trusty: Fuzzer for Gatekeeper TA
trusty: fuzz: Helper library
Adds an Abort() function to the fuzzer utils library that grabs and
prints the relevant trusty kernel logs before exiting the fuzzer.

On devices without a dedicated recovery partition, it is possible that
e2fsck exists in /system/bin, not /first_stage_ramdisk/system/bin, if
it is using generic ramdisk. When force_normal_boot, /system/bin/e2fsck
would not exist during first stage mount.
In this case, move /first_stage_ramdisk/system/bin/e2fsck to
/system/bin/e2fsck before switching root into /first_stage_ramdisk.
Abort if the operation fails.
On devices launching with R, e2fsck should already exist in the correct
place, so skip moving if force_normal_boot and
/first_stage_ramdisk/system/bin/e2fsck already exists.
On devices launching before R, it is possible that /system/bin/e2fsck
does not exist. Skip moving if force_normal_boot and /system/bin/e2fsck
does not exist.

Some functionality based on eBPF attached to tracepoints (gpu memory
accounting and time-in-state) rely on newer devices running with
"disabled" perf_event_paranoid controls as a result of the kernel having
LSM hooks in the perf_event_open syscall instead. This is tested
for, and set up by init via the sys.init.perf_lsm_hooks sysprop.
Development devices that boot into permissive mode still want the
eBPF-based functionality to work, but end up with a paranoid value that
disallows the syscall, as the LSM hook test expects to observe a SELinux
denial (which doesn't happen due to permissiveness).
As a pragmatic way of achieving the paranoid value override, we pretend
that the hook test has succeeded if we detect permissive SELinux during
second-stage init. It'd be nicer if we had a sysprop to reflect the
device's on-boot status of SELinux, but it's not worth adding for this
case.

Tested: booted crosshatch-userdebug with permissive kernel cmdline,
confirmed that the log message from the new codepath was present
in logcat, sysprop is 1, and paranoid is -1.

For devices using utilclamp create cpu controller hierarchy. Do not
remove schedtune hierarchy yet because init.rc is generic and should
work with devices which still use schedtune.
