Add some extra fudge to the termination time. This assumes that flaky
tests were caused by roundoff error.

When the CDM creates a new usage entry for an offline or streaming
license, the new entry is immediately moved to the lowest available
entry index that has been marked as vacant (kStorageTypeUnknown).
When a license is released, its meta data that is managed by the CDM
is cleared; however, the usage entry's index is marked vacant, but it
is not released. This creates wasted entry space in the usage table.
Unfortunately, defragging the table is computationally expensive and
may not be able to actually free up much space depending on when it
is performed.
For a typical user, this will likely not be an issue as the table
can get quite large compared to the number of licenses an app uses
and the table is partially cleaned on each boot.
GTS tests, however, have reached a point where they fill the usage
table before all tests are complete. This is causing many unexpected
failures for devices. Most of these tests release their license, but
the CDM never reaches a state where it can clean up the table.
By moving newly created entries to the lowest available index directly
after creating the entries, the table never needs to grow unless all
entries are in use. Clean up is now almost never required.

There was an issue encountered by some vendors with how the usage
table was initialized on some devices. Previously, the CDM would
open an OEMCrypto session first, then initialize the usage table
(loading existing or creating a new one). On these devices,
OEMCrypto_CreateUsageTableHeader() and OEMCrypto_LoadUsageTableHeader()
would fail if there were any open sessions.
This CL changes the initialization process to create/load the usage
table before opening an OEMCrypto session.
This change also lays the ground work for another usage table fix
to address GTS tests failure.
In the process, several of the functions for the usage table have been
split up into smaller chunks of code. This required additional changes
to the usage table unittest to keep them up to date.

The OEMCrypto tests have tests that verify that entitled keys can be
loaded but not that they can be successfully used for decrypt. This
patch adds a decrypt portion to the existing tests.
As part of this, the existing Session::EncryptCTR() method and portions
of Session::TestDecryptCTR() are lifted to be static functions so they
can be shared across unrelated classes in oec_session_util.cpp.
EncryptCTR() had no dependence on its enclosing class and is unchanged
other than being moved outside the class.
To reduce ambiguity with the new decrypt verification, this patch also
renames EntitledMessage::VerifyEntitlementTestKeys() to the
more-specific EntitledMessage::VerifyKCBs(). Its behavior is unchanged.

GenerateSimpleSampleDescription() only had asserts to check parameters
that only came from other test code, so they weren't testing anything of
use. With the asserts removed, it's no longer necessary to wrap calls to
GenerateSimpleSampleDescription() with ASSERT_NO_FATAL_FAILURE(), which
a lot of callers were already forgetting to do anyway. This also
simplifies a future patch that will generalize the decryption test code
to work with entitlement licenses.

LicenseDurationRemaining used to indicate the minimum of rental or
license duration till OEMCrypto v16. OEMCrypto v16 onwards it began
reporting rental duration alone.
This is confusing for app developers and content partners. Keeping
LicenseDurationRemaining as apps may depend on it but adding
RentalDurationRemaining for clarity.

In b/65839890 we discovered that an android app loaded an offline
license more than once in a session. We did not intend to allow
this behavior but did not prohibit it. OEMCrypto v16 disallowed
this behavior at the OEMCrypto level but we worked around it
within the CDM to maintain the bad behavior. Now that we have confirmed
that the app no longer relies on that behavior, we are reverting
the CDM workaround.
