The specific changes and more detailed rationale is in the commit messages, but the highlights are: * `XoRoShiRo128PlusPlus` (previously a test-only RNG) moves to random.h and becomes `InsecureRandomContext`, which is even faster than `FastRandomContext` but non-cryptographic. It also gets all helper randomness functions (`randrange`, `fillrand`, ...), making it a lot more succinct to use. * During tests, **all** randomness is made deterministic (except for `GetStrongRandBytes`) but non-repeating (like `GetRand()` used to be when `g_mock_deterministic_tests` was used), either fixed, or from a random seed (overridden by env var). * Several infrequently used top-level functions (`GetRandMillis`, `GetRandMicros`, `GetExponentialRand`) are converted into member functions of `FastRandomContext` (and `InsecureRandomContext`). * `GetRand<T>()` (without argument) can now return the maximum value of the type (previously e.g. `GetRand<uint32_t>()` would never return 0xffffffff).

# Unsigned integer overflow occurs when the result of an unsigned integer
|
|
# computation cannot be represented in its type. Unlike signed integer overflow,
|
|
# this is not undefined behavior, but it is often unintentional. The list below
|
|
# contains files in which we expect unsigned integer overflows to occur. The
|
|
# list is used to suppress -fsanitize=integer warnings when running our CI UBSan
|
|
# job.
