main: Add '-devrandom' commandline option
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.
We now require Go v1.13 and Kernel versions should have also moved on.
Make the flag a no-op.

When a process has its working dir inside the mount,
the only way we notice is that we get EBUSY when trying
to unmount.
We used to lazy-unmount in this case, but this means
pulling the rug from under the process.
For example, bash will start throwing
cd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
messages.
Fixes https://github.com/rfjakob/gocryptfs/issues/533
Feedback received during the recent Go user group. If you haven't
used FUSE before, you don't know how to unmount, and it was not
described in the man page!
As for the options, there are many, and new users are intimidated
by it. State clearly that defaults are fine.
When generating man pages, pandoc marks indented code blocks with the
roff macro '.nf'. That avoids a warning from man related to the long
line about the master key.
This adds support for gitignore-like wildcards and exclude patters in
reverse mode. It (somewhat) fixes#273: no regexp support, but the
syntax should be powerful enough to satisfy most needs.
Also, since adding a lot of --exclude options can be tedious, it adds
the --exclude-from option to read patterns from a file (or files).
OpenDir and ListXAttr skip over corrupt entries,
readFileID treats files the are too small as empty.
This improves usability in the face of corruption,
but hides the problem in a log message instead of
putting it in the return code.
Create a channel to report these corruptions to fsck
so it can report them to the user.
Also update the manpage and the changelog with the -fsck option.

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.

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.
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.
