Added trousers, tpm-tools, and tboot.

Added lcp_writepol -Z option.
Added tpm-quote-tools for remote attestation.
Don't let rngd read /dev/tpm0.

Only one process can interact with the TPM module and
that process should be tcsd.  The tpm_rng kernel module
should instead be loaded and /dev/hwrnd be used to
read the TPM random generator.
Also, log which random generator devices are used by
rngd on startup.
Added TCSD (Trusted Computing Group Software Stack (TSS) daemon).

Start tcsd after systemd-udev-settle and run it in foreground.
Add types to tcsd config options.
Only disable TPM access by rngd when tcsd is enabled.
Added meta information and maintainer for trusted computing pkgs.
Changed trousers license from cpl to cpl10.
Merge master into #2129

Conflicts (easy, just UID shifted):
	nixos/modules/misc/ids.nix
	nixos/modules/module-list.nix
PR fixups: use mirror://, drop unused params, etc.

Note: hash of trousers tarball didn't match (anymore),
so I updated it to the one from sourceforge.
It's probably some safe and tiny retrospective update.
Merge #2129: add trusted computing components
