Add libyubikey (aka yubico-c) package
Add ykpers (aka yubikey-personalization) package
Implement authentication for a LUKS device with a yubikey (HMAC-SHA1); supports simple challenge-response and two-factor authentication
Add #include <unisted.h> for sleep and usleep
Rewrite as a pre-boot authentication module (mostly) comforming to the design specification of
'YubiKey Integration for Full Disk Encryption Pre-Boot Authentication (Copyright) Yubico, 2011 Version: 1.1'.

Used binaries:
  * uuidgen - for generation of random sequence numbers
  * ykchalresp - for challenging a Yubikey
  * ykinfo - to check if a Yubikey is plugged in at boot (fallback to passphrase authentication otherwise)
  * openssl - for calculation of SHA-1, HMAC-SHA-1, as well as AES-256-CTR (de/en)cryption

Main differences to the specification mentioned above:
  * No user management (yet), only one password+yubikey per LUKS device
  * SHA-512 instead of CRC-16 for checksum

Main differences to the previous implementation:
  * Instead of changing the key slot of the LUKS device each boot,
    the actual key for the LUKS device will be encrypted itself
  * Since the response for the new challenge is now calculated
    locally with openssl, the MITM-USB-attack with which previously
    an attacker could obtain the new response (that was used as the new
    encryption key for the LUKS device) by listening to the
    Yubikey has ideally become useless (as long as uuidgen can
    successfuly generate new random sequence numbers).

Remarks:
  * This is not downwards compatible to the previous implementation
Adopt more packages.
androidenv: also allow references to individual apk files
Cosmetic change to yubikey detection
lua5: Add the lua-sockets extension.
quvi: Update to current upstream (0.9.4).
quvi: Update the CLI tool to version 0.9.5.
Fix Xmoto build (missing include)
amdadl-sdk: Don't build on Hydra

Since it uses requireFile, it won't build.  Likewise for cgminer which
depends on amdadl-sdk.
Updated dwb to HEAD and used the current date as version number, because dwb has no version numbers.
Merge pull request #1626 from pSub/dwb-update

Updated dwb
Enable two-factor authentication by default. Add proper descriptions to attributes.
tkabber+plugins: Update to upstream version 1.0.

After several years, Tkabber finally got a new release.

The highlights are:

 * Completely rewritten Tkabber internals
 * Dropped Tcl/Tk 8.3 support. Now Tcl/Tk 8.4 is required
 * Partial IPv6 support (requires Tcl/Tk 8.6)
 * Switched from TclGPGME to TclGPG for encryption and signing
 * Added new connection method BOSH (XEP-0124 and XEP-0206)
 * Disabled SSLv2 and enabled TLSv1 TLS options
 * Added user nicknames (XEP-0172) support.
 * Updated the CAPTCHA forms (XEP-0158) support
 * Added metacontacts (XEP-0209) support
 * Implemented multiple proxy profiles
 * Implemented remote controlling from a locally executed script
 * Added new plugins: floatingcontact, poker
 * Rewritten most plugins to support disabling and unloading on the fly
 * A few interface enhancements (search in MUC affiliations lists, proxy
   management)
 * Many fixes and enhancements

tkabber: Don't set a default theme.

If people still want the ocean-deep theme, it can still be set by using:

tkabber.override { theme = "ocean-deep"; }

But by default we should not set a theme, so the user will get the same
result as everyone who installs the upstream version.

tkabber: Properly wrap all scripts in $out/bin.

Alongside "tkabber", there is also "tkabber-remote", which uses the same
variables as the main script and thus needs to be wrapped the same way
as well.

tkabber: Merge main package with site plugins.

The site plugins are released alongside the main Tkabber sources, so it
makes no sense to have them in a separate package (which also introduces
an impurity). In addition, both packages share the same makefile
structure, so it really makes sense to merge them.

Before people might get worried about my decision to enable those
plugins by default: Since version 1.0, Tkabber is no longer loading
_all_ available plugins, but gives you a menu (Plugins Management) to
selectively enable plugins (whereas all plugins are disabled by
default).
