4e5783591f fsck: report skipped corrupt 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.

f3c777d5ea 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.

e36a0ebf18 main: add "-sharedstorage" flag 
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.

26a6e61a46 MANPAGE: update exit codes 
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.

53b7c17261 Don't cap GOMAXPROCS at 4. 
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.

f1945c4daa Add -forcedecode 
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.
