Subject: [PATCH] Update random includes.

PHP 8.4 has some breaking changes with respect to where PHP's random methods and
helpers are.  This commit fixes those issues while staying backward compatible.

Fixes #2463

Subject: [PATCH] We don't need to use a ranom value for our ECHO liveness
 challenge.

A microsecond resolution timestamp combined with a monotonically
incremented counter should be sufficient.

This also fixes PHP 8.4 compilation as PHP 8.4 doesn't seem to have
`php_rand()`.
