Since we started locking down the beesd service, we no longer have
privileges to do some things. Have systemd do it for us instead.

Btrfs mount options effects all mount points using the same Btrfs
partition, so specifing it per-mount is useless.
Also, common mount options like `noatime,nosuid,nodev,noexec` has little
to no effect on beesd, so it's just better and simpler to remove this.

I've verified that using this setup, user will be able to access the log
in /run/bees, but cannot access the mounted filesystem.

Change documentation and comments to use the word "dedupe," not "dedup"
as found in circa-3.15 kernel sources.
No changes in code or program output--if they used "dedup" before, they
will continue to be spelled "dedup" now.

Replace CPU shares and IO block weight by CPU weight and IO weight. Note that new parameters are roughly 1/100 of old one--I believe that's the right conversion. Also removed duplicate Nice parameter and alphabetized the parameters for ease of reading.
Leave AL16M defined in beesd to avoid breaking scripts based on
beesd.conf.sample which used this constant.
Use the absolute size in beesd.conf.sample to avoid any future problems.

`grep -q something | grep -q something_else` will never find anything.
The for-loop is redundant anyways because `grep -l` can already work for
us. Let's replace this with a shorter and working version.

Since systemd prefix it's own timestamps, we can unconditionally remove
timestamps when bees is executed by systemd.

This commit removes USR_PREFIX and introduces ETC_PREFIX instead. The
purpose of PREFIX is the installation prefix in the system, not the
installation destination. The latter one is what DESTDIR is used for.
This should clear up the confusion. PREFIX was already mis-used as
installation destination. But that doesn't mix well with how the make
targets are designed.

Let's direct users to the support site when they ask systemd for help
about the service unit, or by looking at error messages.
Also, let's adjust the description to be more pleasing to the eyes. The
previous long description with uncommon formatting really stuck out in
the boot logs.

Starting bees right after local-fs.target is probably not what we want,
as basic setup of the system might not have been done (like udev,
cryptsetup, sysctl, swap, etc).
Let's start only after sysinit.target instead which guarantees that all
basic setup has been done, most importantly, sysctl, udev, and swap have
been setup which may apply important tweaks, configuration, and tuning.

Due to bees installing into the local-fs.target, bees also runs during
system-update.target. This should not be done, system-update.target is
meant as an isolated bootup mode for applying updates offline, that is:
Only essential services are running.
Fix this by making it WantedBy basic.target instead. According to
system-update.target and "man bootup", system-update.target pulls in
sysinit.target, as does basic.target. So essentially, basic.target is
not part of the system-update.target transaction.

Currently scheme lead to path like:
/tmp/makepkg/bees-git/pkg/bees-git/usr/lib/bees/bees
While packaging, so allow do:
make
make scripts
make install ...
make install_scripts ...

Now with the patches integrated to filter logging output, we can finally
remove forking a subprocess and stop redirecting file descriptors.
We instead use exec to replace the process with the final daemon.

To make bees more friendly to use with syslog/systemd, we add an option
to omit timestamps from the log output.

To install for different distributions, LIBEXEC_PREFIX can now be set.
It defaults to $(PREFIX)/usr/lib/bees as used in most common
distributions.
Local overrides are possible by setting variables in a "localconf" file
which will be included by the Makefile if it exists.
For some distributions you may want to set it to /usr/libexec or
/usr/libexec/bees.
Let's remove the CPUQuota example and instead give bees a share of
what's available.
128 CPU shares will give it about 12% max CPU under load, give it a
slight boost during startup to allow reading the hash table faster.
100 block shares will give it about 10% max disk bandwidht under load,
give it a slight boost during startup to allow reading the hash table
faster.
Then let's adjust the CPU and IO scheduler to prefer other processes.
This way bees runs completely in the background, barely noticable
during, e.g., gaming.
Explicitly set control-group kill mode, that is: try SIGTERM first, and
use SIGKILL after a timeout. This exactly defines how bees is running as
a child process within the frontend service starter. Not sure if bees cares
about signals but SIGTERM first seems cleaner. On the way, let bees restart
on abnormal termination.
