freevxfs: relicense to GPLv2 only

When I wrote the freevxfs driver I had some odd choice of licensing
statements, the options are either GPL (without version) or an odd
BSD-ish licensense with advertising clause.

The GPL vs always meant to be the same as the kernel, that is version
2 only, and the odd BSD-ish license doesn't make much sense. Add
a GPL2.0-only SPDX tag to make the GPL intentions clear and drop the
bogus BSD license.

freevxfs: handle big endian HP-UX file systems

To support VxFS filesystems from HP-UX on x86 systems we need to
implement byte swapping, and to keep support for Unixware filesystems
it needs to be the complicated dual-endian kind ala sysvfs.

To do this properly we have to split the on disk and in-core inode
so that we can keep the in-core one in native endianness. All other
structures are byteswapped on demand.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
