df75c39a58 new parsing for gpg_decrypt function

eada0538c9 Delete mountpoint when tomb is closed (fix #149)
two bugs were left behind by the last refactoring, one about
consistency of the mountpoint naming (now using $TOMBNAME everywhere,
without the added .tomb extension as per #180), the other about a
missing _sudo to prefix rmdir commands.

Test suite has been updated accordingly.

This fix introduces a mandatory condition for the next update: all
tombs must be closed when upgrading the tomb script, else it will not
be able to correctly close them.

de418d00c9 Add detection of plain swap on encrypted volumes. (Fixes #163)
Previously, the code was relying on `file` and `dmsetup` to detect
encrypted swaps, but it was missing plain swaps on encrypted
volumes. Using `lsblk` adds this detection and simplifies the test.

Thanks @fsLeg for reporting the issue, and @boyska for fixing it.

5dbcabdf26 Removed old privilege escalation model
This commit refactors the handling of password input by eliminating
all intermediary programs and relying only on ZSh, hence improving
overall security against rootkits and such.

Also the way sudo is used is now greatly simplified and there is no
privilege escalation at boot: sudo is executed inside Tomb by being
prefixed in front of those programs needing it.

All tests passed.

aba0fa5191 Avoid using a tempfile on every key decryption
A tempfile was often used by Tomb in order to parse the stderr output of
gpg and detect if the password is correct or not. The tempfile was not
holding any secret information (see #162) yet this is an improvement for
Tomb's deniability since there is now much less going on in the temp
firectory.

a10d6af804 Removed handling of temporary directory
Added the --tmp flag for manual selection of the temporary directory, whose security should really be up to sysadmins when configuring operating systems. Default is ZSh TMPPREFIX usually set to /tmp/zsh which, if not existing, will be created as world writable with a sticky bit.

This commit also includes a cleanup of commandline options and a fix to swap check.

e48c7c4a85 Added new --unsafe mode: -k cleartext
Using the 'cleartext' name for a key will read it from stdin and
expect it to be unencrypted. This is an unsafe mode of operation,
but useful i.e. to open remote tombs by piping the key over ssh,
or using a different software than Tomb to de/crypt keys.

This commit also renames the flag --unsecure-dev-mode into --unsafe
and includes a minor fix to the last opened date shown on open.

b7f4e3a7fd Use print for non-escaped piping of secret
after fixing issue #154 with echo here we revert to using print with
options -R -n which sort the same effect. Print is preferred since it
executes the built-in command without any possible ambiguity. We don't
want to expose secrets to an external executable in case of a simple
attack that would change the env PATH to use a rootkitted echo.

489b3582cb Disable escapes when piping secrets
Switched to use echo with -E flag to disable escapes in keys: escape
strings were discarded cryptsetup tomb operations when they were present
in the decoded key random passphrase. Issue #154

The solution adopted here includes wrapping all cryptsetup operations to
unify the behaviour adopted.

Worth noting that this problem possibly breaks all tombs and keys
created using the unstable Tomb from git development in the past 2
months. Regression tests with previous stable releases are OK.
