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).

61940a9c06 Include rendered man page in source tarballs 
This gives users who build from the source tarball, but
do not want to install pandoc, access to the man pages.

Apperently the gocryptfs homebrew package ships without
the man pages at the moment to avoid pandoc.

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.

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.
