2c0d74e8e8 Use the correct location of the EBDA for searching for the RSDP.
The EBDA is the 1 KB area addressed by the 16 bit pointer at 0x40E.

15a3ddef19 Fix a potential stack buffer overflow on systems whose ACPI OEMID
fills its field (6 characters).  In that case the OEMID is not
null-terminated, and the sprintf that was used would copy up to the
next null byte, which could be pretty far away.

d9b97e8dff Use __FBSDID().
Also some minor copyright style cleanups.

c53bcc89ca Null terminate the OEM hint. This rids my laptop of the smiley face that
would follow the 6 valid chars of the table entry.

51773ddf47 Support functions for the new ACPI import.
* AcpiOsDerivePciId(): finds a bus number, given the slot/func and the
    acpi parse tree.
  * AcpiOsPredefinedOverride(): use the sysctl hw.acpi.os_name to
    override the value for _OS.

ad41f9a8f7 Teach the loader how to find the system ACPI information, and autoload
the ACPI module if the system apperars to be ACPI compliant.

This is an initial cut; the load should really be done by Forth support
code, and we should check both the BIOS build date and a blacklist.
