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
name requirements.  This is especially important as C++17 will remove
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.

Test: Linux unittest and Android unittest
