39c12039cb Patch Android FileSystem::List for non-existing directory.
[ Merge of http://go/wvgerrit/210651 ]

The Android FileSystem implementation for List() would return an error
if the directory does not exist.  This creates an issue for the case
where the CDM attempts to list offline licenses after clearing all
data.  This typically won't effect a regular user, it causes
integration tests which re-provision to fail.

b092b0e2f1 Cleaned up file_store_unittest.cpp
[ Merge of http://go/wvgerrit/209871 ]

The filestore unit tests have not been updated in a while, and
contained several test statements which could crash the test
when failed (accessing elements in a vector or characters in a
string without proper size checks).  Other parts of the tests
had non-obvious purposes without detailed knowledge of how the
file system works on the different platforms.

Significant parts of the tests have been refactored to include
better checking and to add error messages to explain the
expectations.  Several of the tests have been documented, and the
FileSystem header has been updated to explain what the API does.

b7b423aca3 Reduce clock skew in flaky duration tests
There are three changes here that should help reduce the
amount of duration test failures caused by clock skew.

First, we reported some skew when the test expected playback
to start immediately after loading the license. However,
with round-off, this could easily be more than 1 second. So
this does not warrent even a warning.

Second, the fake and real clocks were only synced after
computing how long to sleep. This is fixed by moving
SleepUntil to the TestSleep class and having it sync before
computing the delta and after doing the sleep.

Third, I am guessing that some failures due to unexpected
lenience were caused by the rental or playback clock being
started at the end of signing the license or the end of the
first decrypt instead of the beginning. We work around this
by recording how long these operations take, and then adding
this extra time at the end of the check for FailDecrypt.

9d1c9ca76a Add error details when offline license is not found
[ Merge of http://go/wvgerrit/171310 ]

Offline license not found errors are identified by CdmResponseEnum
347 (KEYSET_ID_NOT_FOUND_4). No addition file system information
is shared.

Checks for file existance use the stat command. The stat call can
return error codes from errno.h when the command fails.
These are now converted into sub error codes and returned along with
the offline license file not found error.

This also includes a change to log stat errors other than
ENOENT (no such file or directory) as a warning rather than verbose.

a20ee5bc54 Update system time for OPK reboot tests
[ Merge of http://go/wvgerrit/154593 ]

This CL updates the initial time used for reboot tests to be
within the valid range used by OPK. Also, the fake clock is
now synced with every use of the TestHost's clock function.

Also, the OPK's system clock is no longer initialized to 0
because this caused some tests to set initial playback time
to 0. That broke code that assumed a time of 0 mean "never".

I also removed some log spam in the WTPI code.

6cda6717a9 Reboot test: Initialize fake clock
[ Merge of http://go/wvgerrit/143630 ]

When we run a test with the fake clock, the clock had been initialized
to the current time, or to 0. This causes a problem for reboot tests
because the clock might go backwards over the reboot. With this
change, we monitor the clock at the end of one reboot pass and
initialize the clock for the next pass based on the previous value.

e51f869190 Base64 encoding for string input.
[ Merge of http://go/wvgerrit/119805 ]

This change adds 3 new functions for encoding binary data from a C++
string to a base64 encoded ASCII string.

The CDM and protobuf generated code use C++ strings to store binary
data.  These binary strings are commonly converted into a base64
encoded ASCII string for logging and for returning to the app.

This change also cleans up some of the internal components of the
string_conversions library to use several standard library C++11
method.

3b15087627 Allow two DRM certificates for each identifier
[ Merge of http://go/wvgerrit/119684 ]

This allows for a default DRM certificate that includes an expiration
time and a legacy one without for each app+origin specific identifier.
Existing offline licenses/secure stops are not associated with a
certificate, and so we cannot delete legacy certificates even after
fetching a new one. New offline licenses/secure stops will be associated
with certificate information, so we will not have this problem going
forward.

48122e2c11 Fix TimeRollbackPrevention Test
(This is a merge of http://go/wvgerrit/107243.)

This code is based on a bug report and patch from Sony.

The TimeRollbackPrevention test was failing when run with CE CDM and the
OEC Ref, although it passed in some other configurations. The cause was
twofold:

1) The test sleep code was not accounting for rollback when calculating
   the clock drift, causing incorrect time values to elapse.
2) Fixing the previous exposed a bug in the CE CDM test host where it
   did not handle negative time passing correctly.

This patch expands Sony's fix with additional comments and some code
cleanup to try to make the code clearer and more robust against future
errors, particularly in the error-prone TestHost code.

7ab69e7768 CdmRandomGenerator meets UniformRandomBitGenerator named requirements.
[ Merge of http://go/wvgerrit/89766 ]

Certain C++11 (and newer) standard library functions and classes which
utilize random number generators require that the random number
generators meet the specifications of C++11's UniformRandomBitGenerator

support non-compliant alternatives.

This change updates CdmRandomGenerator to meet these requirements.

ee56d93454 Creating a new RNG and replacing rand().
[ Merge of http://go/wvgerrit/84607 ]
[ Merge of http://go/wvgerrit/84608 ]

The primary goal is to replace the use of `rand()` with the random
number generators provided with the C++11 standard.

This simplified generator wraps some of the technical aspects of the
<random> library and provides an interface for uniformly distributed
integers.

As part of the `rand()` purge in the CDM, all uses of the C random int
function in `core()` have been removed.  Places that previously used
`rand()` now use `CdmRandom` facilities.
