Where the suggestions came from is not that useful, just have a
single file for the main ones and then distro specific versions.

- make quiet
- force, so some adjustments are not checked see https://github.com/docker/pinata/issues/6198
- set resize_inode as we do resize partitions on cloud and they could have very few inodes otherwise
- inline all the default options and remove the config file, so script is more standalone

Previously we only ran `fstrim` on Windows. Docker for Mac now supports
TRIM so we should run `fstrim` there too.
Note it's possible to turn off TRIM on the Mac at the virtual hardware
level via the database, but this should be harmless -- the `fstrim`
fails immediately with an obvious error if the device doesn't support it:
`fstrim: ioctl 0xc0185879 failed: Not supported`.

- this needs an init as it does not respond to stop signals, so include tini
- needs CAP_SYS_ADMIN to write to kernel entropy estimate
- set kernel.random.write_wakeup_threshold so that rngd does not need sysctl write access
- build patches from Alpine, but statically linked
- remove rngd from base image, means we no longer need community repository

This makes sure that once we have ro rootfs any programs that still
for any reason use `/tmp` can still write to it, or if people expect
sharing it into a container to work.

- run bootmisc before sysklogd so symlinks from /var/run to
/run are created
- recreate symlinks that bootmisc created when we remount /var
until this gets moved earlier

If we are using vsudd to forward syslog to the host, as on osx,
we need to start it before syslog starts, and make sure it has
created its socket.
Add a pidfile to vsudd to make startup more reliable.

This reverts commit 4dd5dca106.
Fix#710 where system hangs after klogd startup on AWS. Possibly
also affects Windows too. Still unclear why but lets revert and
continue investif=gating.

So that we can write to /var early, move filesystem formatting as early as possible.
Adds a dummy fsck service, as we already do fsck in format script.

Tweak the config to use RDSEED or (fallback) RDRAND. Makes sure
we have initial random seed in cases where there is no other
random source if these are supported.
The default config in Alpine currently disables these, which makes
it pretty useless, as there is no motherboard rng support any more.

Given you can login as root with no password on the console,
asking which user you would like to login as is rather pointless.
Do have to tweak /etc/issue though as busybox getty does not display it
without a prompt, and we want a whale.

This is needed for volume drivers as they will mount their
volumes under here, and if they are running in a container
docker on the host will need to see these.
Also provide our own fstab, removes the media devices that were
there previously.

Avoid doing this on non-Docker-for-{Mac,Win} editions (which don't run vsudd)
by checking for vsudd.pid and avoid doing it on Docker-for-Win (for now) by
checking for /sys/bus/vmbus (as /etc/init.d/vsudd does too).
Ideally we would just check for /var/run/syslog.vsock but this may not have
arrived yet (typically vsudd is now started immediately prior to syslog and it
forks via start-stop-daemon and thus before it creates the socket). Since
syslogd will reopen as needed we don't want to delay boot either here or in the
vsudd initscript to await the arrival of the socket.
