Support input to "finish()" in AndroidKeymaster operations.
This CL does not yet take advantage of the simplifications that allowing
input to finish() provides. That will require updating the Java layer
first, to remove some assumptions and code that assume update() must
eventually consume all input.

Add support for KM_TAG_MIN_MAC_LENGTH.
HMAC and AES-GCM keys must be bound to a mininum MAC/tag length at
creation, and operations may not specify a length smaller than the
minimum, or provide a length smaller than the minimum during
verification.

Add buffer wrap checks and disable throwing of std::bad_alloc.
Android is built with exceptions disabled, but "operator new" and
"operator new[]" still throw std::bad_alloc on failure rather than
returning new. In general this is a good thing, because it will cause
an immediate crash of the process rather than assigning a null pointer
which is probably not checked. But most memory allocations in Keymaster
are checked, because it's written to run in an environment where new
does *not* throw. This CL updates the code to explicitly use the
non-throwing new.
A handful of throwing news remain, but only in places where a crash on
failure is appropriate.
In addition, this CL also inserts buffer wrap checks in key locations
and changes the development-machine Makefile to build in 32-bit mode, to
make memory problems more apparent.

Add begin_params to CreationOperation.
Allowing several crypto parameters to be repeated on keys means we need
to be able to specify them at operation time, which means they'll be
passed in to the begin() params. This change makes it possible for
operations to actually receive these values.

Generate nonce if caller doesn't provide one.
If the key has KM_TAG_CALLER_NONCE, then the caller is allowed to
provide a nonce. Previously the assumption was that the caller was
_required_ to provide a nonce. But to play nicer with the Java crypto
API, it's better to make the caller nonce optional if
KM_TAG_CALLER_NONCE is true.
