Fix SoftKeymaster handling of EC curve specification.
Keymaster2 should accept EC curve specification either by key size (as
done in KM1) or with the new KM_TAG_EC_CURVE, filling in the other value
if not specified, and validating that they match if both are
provided. SoftKeymaster doesn't correctly implement this KM2
requirement.

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.
