add glog 0.3.3
hiphopvm: update to commit 1e23dec9f0
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
add arpack-3.1.4
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.
calibre: upgrade from 1.20.0 to 1.21.0
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.

Updated dwb
Enable two-factor authentication by default. Add proper descriptions to attributes.
