New methods:

  • hashEquals() - constant-time string comparison
  • randomBytes() - pulls random bytes from whichever entropy source is available
  • safeStrlen() - mbstring.func_overload-safe strlen() (used by hashEquals())
New methods:

* `hashEquals()`
* `randomBytes()`
* `safeStrlen()`
Optimize `hashEquals()` by caching the result of `function_exists()`.

Also fixed a slight inconsistency with `phpversion()`.
