Replace the remnants of engine.cpp with better functionality in
FastBootDriver. Particularly, add prolog() and epilog()
callbacks to FastBootDriver for printing actions and their result to
the console. Then clean up the rest of fastboot.cpp to directly use
FastBootDriver.
Test: fastboot works

MetadataBuilder::AllocatableSpace() represents the total space
available. Adding MetadataBuilder::UsedSpace() to represent the
space used by the existing set of partitions. This will allow a
caller to predict if a partition can be resized (Grown), or to
create a partition to use up the free space (i.e. scratch).

For non-A/B devices, the recovery partition should be
self-sufficient and not depend on any other partition.
Since recovery may need load ACPIO before access to devices,
we need to make sure that the the recovery image also contains
the information from the ACPIO image.
Test: can generate image with acpio/acpi

TEMP_FAILURE_RETRY's result was unused for the call to read(), so now
mark it as such to silence a possible unused result warning. For
__read_chk(), this function is an internal implementation detail of
FORTIFY in Bionic. Under clang-tidy, FORTIFY checks are actually
removed, so this now results in an unknown function being called. The
code should not be explicitly depending on an implementation detail, but
we can just suppress the failing case to retain test coverage of the
actual implementation.

CheckRequirements() had various issues that are cleaned up here,
1) Move from C string parsing to C++
2) Moved from C data structures to C++, including fixing memory leaks.
3) Removed the 'cur_product' global and the 'query_save' function that
stores it
4) Actually writing tests for the parsing function for
android-info.txt
5) Check that a variable needs to be checked for a given product before
trying to read it. Previously, fastboot would fail if a variable
isn't recognized on a device, even if the check should be ignored.
A lot of flexibility is allowed for the input strings, to keep
backwards compatibility with the previous parsers.
Test: fastboot works, unit tests

This change makes the subcontext processes cleanly exit in the event of
the init's socket being closed. If that was an accident, init will
respawn the process immediately. Otherwise, it will just quietly go
away.

Adds support for partitions with checkpointing enabled. If the
checkpoint= fs_mgr flag is set, and the system has checkpointing on,
the partition will be mounted in checkpointing mode.
Test: Use vdc checkpoint commands, the checkpoint=fs fs_mgr flag
in the fstab, and a kernel containing the f2fs checkpoint
changes. https://lkml.org/lkml/2018/8/21/22

Debugging memory allocations on the nexus launcher unveiled significant memory allocations for the hashatable used in libziparchive, ~1MB.
This is partly because of the ZipString struct storing an entry in the table. The struct stored a pointer to a string (on 64 bit, 8 bytes) and the length to read from that pointer, 2 bytes. Because of alignment, the structure consumed 16 bytes, wasting 6 bytes.
Now, we store entries in the hashtable as a ZipStringOffset. This new structure stores a 4 byte offset from a fixed location in the memory mapped file instead of the entire address, consuming 8 bytes with alignment.
Bug: 79416399
Test: Builds successfully and manual testing by opening launcher on Pixel 2 shows precisely 50% decrease in memory allocated for the hashtable. From 909312 bytes to 454656.

Modify TrustyKeymaster3Device::update method to handle the case when
amount of input data received exceeds a maximum amount supported by
underlying transport. In such case, only send an portion of data that
fits and allow higher levels to take care of the rest.
This is not an ideal fix as it is not very efficient for large sets
of data but at least it should work in more cases.
