Allows to use /dev/random for generating the master key instead of the
default Go implementation. When the kernel random generator has been
properly initialized both are considered equally secure, however:
* Versions of Go prior to 1.9 just fall back to /dev/urandom if the
getrandom() syscall would be blocking (Go Bug #19274)
* Kernel versions prior to 3.17 do not support getrandom(), and there
is no check if the random generator has been properly initialized
before reading from /dev/urandom
This is especially useful for embedded hardware with low-entroy. Please
note that generation of the master key might block indefinitely if the
kernel cannot harvest enough entropy.

At the moment, it does two things:
1. Disable stat() caching so changes to the backing storage show up
immediately.
2. Disable hard link tracking, as the inode numbers on the backing
storage are not stable when files are deleted and re-created behind
our back. This would otherwise produce strange "file does not exist"
and other errors.

...if the filesystem was created with that option (or reverse
mode).

The exit codes have been documented in CLI_ABI.md for a while,
but they should also be listed in the man page.
Also fix the rendering of "[-o COMMA-SEPARATED-OPTIONS]", where
the square brackets where interpreted as something. Escape all
square brackets to be safe.

For some reason, writing became a lot faster in Linux 4.11
(scheduler improvements?).

Massive speed boost for streaming reads.

Slight streaming write improvement.

Also, get rid of the half-empty line.

Before Go 1.5, GOMAXPROCS defaulted to 1, hence it made
sense to unconditionally increase it to 4.
But since Go 1.5, GOMAXPROCS defaults to the number of cores,
so don't keep it from increasing above 4.
Also, update the performance numbers.

Needs a leading "..".

All exit codes that are likely to occour are listed.

...and fix a few golint issues and print a scary warning message on mount.
Also, force the fs to ro,noexec.

Force decode of encrypted files even if the integrity check fails, instead of
failing with an IO error. Warning messages are still printed to syslog if corrupted
files are encountered.
It can be useful to recover files from disks with bad sectors or other corrupted
media.

This makes it render properly on the github webinterface.

* Further explain the use of 'scryptn' parameter
* Further explain the use of 'scryptn' parameter in MANPAGE
* Use 28 as reasonable upper limit

This keeps the README working even if nuetzlich.net is unavailable.
We use a PNG because github disallows embedding local SVGs.

The old ones were rendered by github almost as big as the parent headings.

Writing 1000 128KB blocks takes only 1 second and yielded
inconsistent results. With 2000, things look saner.

Preallocation is very slow on hdds that run btrfs. Give the
user the option to disable it. This greatly speeds up small file
operations but reduces the robustness against out-of-space errors.
Also add the option to the man page.

"-f" looks too much like "--force". The old variant is still
accepted for compatability.
