The QueryKeyControl test expects an error message that the output
buffer is too small. However, it also gives a bad key id. Some
devices were correctly returning key not found. This corrects the key
id length so that the only error is that the buffer is too small.

This cleans up some tests in oemcrypto_test.cpp so that they use
vectors instead of arrays. The two reasons this is needed are that
arrays are more likely to use up stack space, and that arrays on the
stack are not initialized.
The lack of initialization caused some negative tests to fail because
buffers that were reused from unencrypted data still contained values
that the test expected not to be there.

It is expected that OEMCrypto will only be given subsamples with a
block offset when there are multiple subsamples, so that the entire
sample may be decrypted after all calls are made. This CL modifies
the existing tests so that the result of DecryptCTR is only checked
after all subsamples have been decrypted.
Also, the QueryKeyControl test has been modified so that failure does
not require a specific error code.

The unit test PreventNonceFlood3 opens 8 sessions and floods the nonce
table. It then opens one more session after a pause to verify that it
can still request nonces. However, there is no requirement that we
can open more than 8 sessions. This CL reuses one of the already open
sessions to verify that we can continue generating nonces.

Add Level 3 Oemcrypto Unit Tests To Run All Tests Script
This CL adds the ability to restrict the oemcrypto unit tests to only
use the fall back level 3. This restriction is per-process, and is
only used while running the unit tests. This allows us to automate
running the unit tests on an android device as both level 1 and level
3 without modifying files in /system/lib. To turn on the restriction,
set the environment variable: FORCE_LEVEL3_OEMCRYPTO=yes.
New level 3 library versions are:

This change:
1) Switches the Makefiles over to using LOCAL_STATIC_LIBRARIES, which I
understand is the new hotness, rather than setting a -I flag directly.
2) Switches to the non-deprecated _ex versions for EVP_EncryptFinal.
3) Uses the EVP_PKEY interface for checking PSS signatures. This is the
only supported interface in OpenSSL: the PSS padding check functions are
only exported in upstream OpenSSL because it's a library from the 90s
and they don't have a concept of "unexported". Also, by using the EVP
functions, OpenSSL/BoringSSL can do a better job of being constant-time.
Since there aren't any obvious tests for checking that the signtaure
verification still works, I tested with the code in the referenced
paste, which includes both the old and new verification functions and
checks that they both work on a sample signature. (And I also checked
that they both fail when a bit in the signature is changed.)

There was a memory leak in the oemcrypto RSA code.
Also, when saving the usage table, some session variables were

haystack. It will warn if a variable is left unencrypted or is
unencrypted twice. I also added the profile code.

This cleans up our includes to be in Google Style Guide order and in
alphabetic order, for the parts of the code that are expected to
follow Google Style.
This also converts places in our code that were including C headers
in the C++ style (i.e. <cstring> instead of <string.h>) to use C style
instead. This is because, although it was not causing problems for us
yet, on Android these actually include different headers. (<cstring>
is provided by libcxx, while <string.h> is provided by Bionic)
Lastly, this change puts all headers that do not come from within our
project in <brackets> instead of "quotes," which was not being done
consistently.
This change is explicitly NOT trying to standardize the spacing of our
header includes. I have tried to respect, in each file, the spacing
style already present.

The OEMCrypto library should prevent too many nonces from occuring in
a row. Previously, we tested that GenerateNonce generated an error if
there were too many nonce requests.
This CL makes it possible for OEMCrypto to delay the return from
GenerateNonce if there are too many requests. This is an equally
valid solution to the nonce flood attack.
This is a unit test change only. No production code is affected.

It is an error for the key control block to have a nonzero replay
control flag and a null pst. This CL adds unit tests to
