6c96352a06 Remove support for autoloading ACPI from the loader. Leave in the code to 
detect ACPI and export info such as the location of the RSDP via hints as
that is still useful.

e85b664cd2 Don't warn about an RSDP with a corrupt checksum. The kernel does a better 
job about warning about these things later and this message can be
confusing.

b5fd832d94 Use PTOV() to convert physical addresses to appropriate virtual addresses 
in the loader when searching for the ACPI RSDP.  (The loader runs in a flat
mode with va 0 == pa 0xa000.)

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.
