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.

We used to do validation using lists of mandatory feature flags.
With the introduction of XChaCha20Poly1305, this became too
simplistic, as it uses a different IV length, hence disabling
GCMIV128.
Add a dedicated function, Validate(), with open-coded validation
logic.
The validation and creation logic also gets XChaCha20Poly1305
support, and gocryptfs -init -xchacha now writes the flag into
gocryptfs.conf.
Our git version is v2+ for some time now, but go.mod
still declared v1. Hopefully making both match makes
https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work.
All the import paths have been fixed like this:
find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%
This makes fsck runs deterministic again.
Sorting (commit quoted below) got lost while
moving to go-fuse v2 api.

fsck: sort files alphabetically
This makes fsck runs deterministic.

Also make sure we actually run "go vet" against the whole
codebase.
Everything except the
if err2.Err == syscall.EOPNOTSUPP
case. Gets too confusing when collapsed into a single line.
