New version released, 3.10

[Jesse Smith]

We're releasing a new version of SysV init. This new release, 3.10, 
provides one new feature and one bug fix, along with some clean-up to 
documentation.

When the user executes "machinectl stop", systemd sends SIGRTMIN+4 to 
PID 1 in the container, and expects that to initiate a graceful shutdown 
(power-off). SysV init now catches this signal and initiates a shutdown 
(shutdown -hP now).

Fix issue in bootlogd which could cause the service to enter an endless 
loop (and use too much CPU) when it is able to open a device for 
writing, but not actually able to write to it. This resulted in bootlogd 
closing and re-opening the device over and over. Now bootlogd should 
simply fail gracefully when it cannot write to an open file/device.

Fix formatting in shutdown.8 manual page. Cleaned up whitespace and 
special characters.

The source code can be downloaded and issue reports filed at the SysV 
init GitHub page: https://github.com/slicer69/sysvinit/releases/tag/3.10
