Add Cloudius copyright and license statement to drivers/*.

A couple of header files were based on Linux's BSD-licensed header files
(e.g., include/uapi/linux/virtio_net.h) so they included the BSD license,
but not any copyright statement, so we can just replace that by our own
statement of the BSD license.

We are currently using PCI's brute force enumeration, which consists of scanning
all possible combination of b,d,f. This makes us issue many inb operations, a lot
more than we could do if we were using smarter enumeration. In my system, the inbs
alone account for more than 5M cycles, which takes around 4s to run (remember this
is xen, it is faster in KVM)

We can do a lot better by using recursive discovery, and only scanning the buses
we need to. In the case of virtual systems the difference is even bigger, since it
is very unlikely that we will have any complex setup with more than one bridge.

Boot for me feels instantaneous now (once we get to start OSV)

Rename all 'log' functions of class log into 'wrt'. The reason is that BSD has a #define log line and there was a clash

Added pci config capability parsing and moved the virtual call to earlyInitChecks() to the base class

Eventually loader dump them into the console for debug

This allows generic code to include arch specific code, by eliding the
arch/x64/ prefix.

We will never build a single program containing code from two architectures,
so segregating arch-specific code into a separate namespace is not solving
any problem.  However it makes using arch-specific code from generic code
impossible.

Remove the 86 namespace to fix this.
