When adding a new partition, don't attempt to map a source partition
during boot, because none exists. Instead use the base device.

Make the queue depth of loop devices identical to that of the underlying
storage device. This patch reduces latency by lowering the queue depth.
With this patch applied I see the following:
# cat /sys/block/loop30/queue/nr_requests
32
Bug: 194450129
Test: Built Android images, installed these and verified that the queue depth of loop devices is 32 instead of 256.

From https://engdoc.corp.google.com/eng/doc/devguide/cpp/styleguide.md:
"Prefer using return values over output parameters: they improve
readability, and often provide the same or better performance (see the C++
Primer)." Implement this advice for ExtractBlockDeviceName(). This patch
does not change any functionality.

With VAB we encourage a smaller super partition, so make sure we delete
"other" slot partitions during flashing. Otherwise, we may not have
enough space in super.

The KeyMint TA may send responses that are longer thant the 8K buffer
that the KeyMint HAL holds. This patch introduces
trusty_keymaster_call_2 which can grow the receive buffer on demand.

Look for the fstab file in /system/etc as an alternative to /, in order
to allow fstab files to be installed using the "prebuilt_etc" Soong
module.
This new path is meant to be used by the vendor ramdisk only. As before,
fstabs should *not* be placed in /system/etc on the system partition.
In more detail: sometimes, multiple nearly-identical fstabs need to be
installed to a device, with the correct one being selected at boot time
(b/191417025 as well as other cases that partners have run into). To
avoid error-prone duplication of configuration files, these fstabs
should be generated from a template by the build system instead of being
duplicated in the source tree. But if this is done, the usual way of
installing fstabs (PRODUCT_COPY_FILES) can't be used; they need to be
made into real build system modules instead.
Currently, the "prebuilt_etc" Soong module can't correctly install the
vendor_ramdisk copy of the fstab(s), since it will install it into the
/system/etc directory whereas Android currently requires that the
vendor_ramdisk copy of the fstab(s) be placed in the root directory.
Earlier I proposed adding a "prebuilt_fstab" module to handle this quirk
(https://r.android.com/1744033). However, it was requested to instead
always look for the fstabs in /etc too, in order to allow "prebuilt_etc"
to be used and because /etc is the appropriate place for this file.
This change implements that suggestion (but actually using /system/etc,
since that is where "prebuilt_etc" actually installs it).

This change adds the RPK apk back into the image for Trusty Keymint
devices, though the functionality will still be disabled by the
server check-in for now.
