macos does not have lazy unmount, so let's not use it
on linux either.
If the unmount fails, run "lsof" to find the open file.
Also fix the first bug we found this way.
test-without-openssl.bash now fails, as it should:
gocryptfs has been compiled without openssl support but you are still trying to use openssl
mount failed: exit status 18
FAIL github.com/rfjakob/gocryptfs/tests/matrix 1.943s
We relied on the finalizer to close a few fds.
For some reason, this did not cause problems on Linux,
but on MacOS, it causes unmount failures:
umount(/private/tmp/gocryptfs-test-parent/194654785/default-plain): Resource busy -- try 'diskutil unmount'
To Go test logic waits for stderr and stdout to close, so
when we share it with a subprocess, it will wait for it to
exit as well.
We don't want the tests to hang when the unmount fails.
Seen on MacOS as reported at
https://github.com/rfjakob/gocryptfs/issues/213
A few places have called tlog.Warn.Print, which directly
calls into log.Logger due to embedding, losing all features
of tlog.
Stop embedding log.Logger to make sure the internal functions
cannot be called accidentially and fix (several!) instances
that did.
Go 1.10 has introduced test result caching and
enabled it by default.
This does not work properly for our integration
tests because they test the compiled binary and
do not have a source level dependency on the
gocryptfs code.
Disable caching.
We now print the number in a debug message, so define
the numeric values explicitely instead of using iota.
This way you don't have to understand how iota works
to find out what the number means. Lack of understanding
of how iota works is also the reason why the numbers
start at 3 (to keep the current behavoir).
Overwrite the masterkey with zeros once we
have encrypted it, and let it run out of scope.
Also get rid of the password duplicate in
readpassword.Twice.
As soon as we don't need them anymore, overwrite
keys with zeros. Make sure they run out of scope
so we don't create a risk of inadvertedly using
all-zero keys for encryption.

Both fusefrontend and fusefrontend_reverse were doing
essentially the same thing, move it into main's
initFuseFrontend.
A side-effect is that we have a reference to cryptocore
in main, which will help with wiping the keys on exit
(https://github.com/rfjakob/gocryptfs/issues/211).
$ go.gcc build
# github.com/rfjakob/gocryptfs/internal/syscallcompat
internal/syscallcompat/unix2syscall_linux.go:32:13: error: incompatible types in assignment (cannot use type int64 as type syscall.Timespec_sec_t)
s.Atim.Sec = u.Atim.Sec
^
On mips64le, syscall.Getdents() and struct syscall.Dirent do
not fit together, causing our Getdents implementation to
return garbage ( https://github.com/rfjakob/gocryptfs/issues/200
and https://github.com/golang/go/issues/23624 ).
Switch to unix.Getdents which does not have this problem -
the next Go release with the syscall package fixes is too
far away, and will take time to trickle into distros.
