416080203b main: accept multiple -passfile options
Each file will be read and then concatenated
for the effictive password. This can be used as a
kind of multi-factor authenticiton.

9178aa1534 MANPAGE: describe how to unmount, and that default options are fine
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.

372e0333b3 Fix 'cannot adjust line' warning from man in gocryptfs manpage.
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.

3bc100aeb3 reverse mode: support wildcard exclude (--exclude-wildcard)
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).

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.

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.

0f8d3318a3 main, fusefrontend: add "-noprealloc" option
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.
