While handling the fatal signals and abort, exits from the signal
handler to panic the system if "androidboot.init_fatal_panic" in cmdline
is configured as "true".

IImageManager::CreateBackingImage and ZeroFillNewImage now returns
FiemapStatus, which is an error code and provides more information
about the reason of error.
In particular, the error code is NO_SPACE if disk space is full during
allocation / writing.

Add variants to SplitFiemap::Create and FiemapWriter::Open that
returns a FiemapStatus and take a unique_ptr<T>* out parameter to
get more information on the reason of the failure.

Commit Ida1a6da988c10d364b3ccdaa6c5d63e5264d1b27 allows specifying
AVB-related partitions to be probed in first-state mount, e.g.,
"avb=vbmeta_system" in the fs_mgr_flags will make init wait uevents
for vbmeta_system partition, which is required for AVB verification.
However, when specifying "avb=dtbo" to chain a /dtbo partition, first-stage
init will emit the following error as it assumes all partitions are
verified by Hashtree descriptors.
init: [libfs_avb]Hashtree descriptor not found: dtbo
This change fixes this by skipping raw partitions for first-stage mounting,
where raw partitions should already be verified by bootloader with Hash
descriptors. Although first-stage init does not perform Hash verification,
it still reads all Hash/Hashtree descriptors to calculate then compare
the "VBMeta Digest" passed from bootloader.

The following is an example of a fstab entry to chain /dtbo partition:
/dev/block/bootdevice/by-name/dtbo /dtbo emmc defaults slotselect,avb=dtbo,first_stage_mount
Bug: 146935233
Test: enable /dtbo as a chain partition, then boot the device

With b/144533348, there will be symlinks from libs in APEXes to the libs
in the system partition. This is to reduce the size of APEXes when the
APEX is bundled with the platform.
Adding the /system/lib to the permitted paths so that the realpaths of
the symlinks are allowed for the namespaces.
Note that this however does not open all libs in the system partition to
the APEX namespaces, because searching of the libs are NOT done in
/system/lib, but in /apex/<module>/lib directory.

Now, the number of elements in each simulated stats_event is correctly
sampled from a uniform distribution.
Rerunning the benchmarking tests indicates that truncating the buffer
increases the number of cycles require to log an event by only 1.6%.
