Filter storage status codes to ensure valid range.
This makes sure any storage status codes coming from the persistence
layer are within the known range. Any status code outside the range
are mapped to kStorageError. This adds an extra safety net that
catches misbehaving storage implementations or problems with linking
stale NVRAM object code after adding status code definitions at run
time.

Add commands for clearing NVRAM on full reset.
This adds commands that allow clearing the entire NVRAM contents. This
can be used by firmware to implement the correct behavior as part of
device recovery. There's always the risk of malicious invocation of
the reset logic, so the new code is behind a compile flag which isn't
enabled by default.

Isolate crypto implementation details.
This moves the details of interfacing with crypto libraries behind a
clean interface, so crypto can be swapped out as needed. Now that
swapping out crypto libraries is easy, use BoringSSL for the main
Android build. We can now always replace it with something else if
that's need in other environments.

Add support for get_max_space_size_in_bytes().
This method, added in v1.1 of the HAL, allows an implementation to
report the maximum supported size for a single space.
This CL also includes a few enhancements to improve testing and adds a
top level Android.mk for convenience.

Fix format constants for fixed-with integer types.
The code should use PRI... macros from inttypes.h when formatting
fixed-with integer types. This prevents compiler warnings due to
mismatches between actual type size and the compiler-target dependent
standard format constants.

Additional unit tests for NvramManager.
Add unit tests for the remaining NvramManager operations. This
actually uncovered buggy behavior in edge cases when operations run
into errors but don't leave the system in predictable internal state.
This change fixes these issues as well, so the tests pass.

Implement support for write-extend NVRAM spaces.
Implement NV_CONTROL_WRITE_EXTEND, i.e. access-controlled NVRAM spaces
that are hash-extended on write. This can be used for anything that
employs hash-chaining, e.g. for audit logging.
