Finit v4.15-rc1

Changes

• Change default reboot to SOC reset from WDT reset, issue #460
• Bump required versions of libite (v2.6.2) and libuev (v2.4.1)
• Allow longer service identifiers (:id), up to 64 characters
• Allow skipping bootstrap wait (180 sec) with Ctrl-C
• Unlock initctl commands start/stop/restart/reload service during bootstrap,
  shutdown, and reboot. Also, allow initctl reload in bootstrap. This makes
  it possible to start manual:yes type services at botostrap, for example, which
  has been a common feature request
• Add support for clone3() syscall with atomic cgroup assignment, from Linux
  kernel 5.3+. Eliminates race conditions where forked processes (e.g., logger
  processes) ended up in wrong cgroups. Falls back to fork() on older kernels
• Add support for cgroup delegation, useful for, e.g., container runtimes
  creating sub-groups for the container instance's processes
• Add cgroup leaf name override: cgroup.system,name:udevd allows using
  descriptive names like /system/udevd/ instead of filename derived names
  like /system/10-hotplug/. Syntax supports combining with other options:
  cgroup.system,name:foo,delegate,cpu.max:10000

Fixes

• Fix #453: RTC plugin fixes by Ming Liu, Atlas Copco
• Fix #455: ANSI escape sequences logged by tools using glib logging,
  caused by use of PTY instead of pipe for stdout/stderr redirection
• getty: fix terminal scrollback issues after login on console TTY. Mouse
  scroll wheel and Shift+PgUp/PgDn sometimes would not work properly
• Fix flickering and artifacts in initctl top
• Fix file descriptor leak in initctl top
• Fix incorrect "max" limit reporting in initctl [top|cgroup|--json] output
  for child cgroups. Resolves effective limits by walking the cgroup hierarchy
• Ensure mount/unmount skips noauto entries
