HVM SMBIOS v2 0/5

The following patches are a cleaned up version of the HVM SMBIOS patches I submitted last Friday.

I apologize if these are posted twice -- the first time I tried to send them I didn't see them show up after 40 minutes...

Differences include

(1) SMBIOS is no longer optional for HVM domU's.
(2) The refactoring I did of hvmloader wasn't really necessary, so I got rid of it.
(3) The patches have been tested on changeset

10671:b20580cf7fc1bfe5119597bb5b576cdd020551d5

(4) The versions of strcpy() and strncpy() I wrote in util.c now behave properly: strncpy() pads the destination string with NULs until its size limit is reached and both strcpy() and strncpy() return the address of the destination string.

Peace.

These patches need rebasing to changeset 10948 or after. The changes I made there should make your patchset rather smaller!

The main thing is to get rid of your additions to hvm_info_table:
1. Uuid can be got via hypercall_xen_version(XENVER_guest_handle)
2. Version info can be got via other XENVER_ commands
3. Memsize can roughly be worked out from the e820 table

I see you add a util.c -- I actually also made the same cleanup in my changeset although I think you add another couple of functions.

Hopefully the way to use the hypercalls is obvious from the above changeset. I added a simple example to hvmloader.c:init_hypercalls() to print version information.

Thanks,
Keir
