Jan Malakhovski 916fa0a610 xen: rewrite build expression to be more modular, support upstream qemu and seabios
Also:

* provides a bunch of build options
* documents build options config in longDescription
* provides a bunch of predefined packages and documents them some more
* sources' hashes stay the same

Vanilla version of Xen. Uses forks of Qemu and Seabios bundled
with Xen. This gives vanilla experince, but wastes space and
build time: typical NixOS setup that runs lots of VMs will
build three different versions of Qemu when using this (two
forks and upstream).

longDescription = ''
Slimmed-down version of Xen that reuses nixpkgs packages as
much as possible. Different parts may get out of sync, but
this builds faster and uses less space than vanilla. Use with
`qemu_xen` from nixpkgs.

Slimmed-down version of Xen without `qemu-traditional` (you
don't need it if you don't know what it is). Use with
