Since we can only override the DSDT, a custom ASL dumped previously that
contained SSDTs would result in lots of multiple definition errors.
A longer-term fix involves adding the ability to override SSDTs to ACPI-CA.

This gets us the info we need on systems which have proprietary tables that
don't match the standard. For instance, an AMI system has a table of type
"OEMB" with an invalid checksum.

and explicitly mention SSDT when we talk about the DSDT so that people
don't have to guess whether it includes the SSDT.

now include the contents if any SSDT table as well. This makes use
of the property that one can concatenate the body of SSDT tables to
the DSDT, updating the DSDT header (length and checksum) and end up
with a larger and valid DSDT table. Hence, this also works with -f.

where the RSD PTR can actually occur. According to section 5.2.2
of the ACPI spec, we only consider two regions for the base address:
1. EBDA (0x0 - 0x3FF)
2. High memory (0xE0000 - 0xFFFFF)
I don't know whether this fixes any actual problems but is more correct.

What is the HPET I hear you ask? It is the High Precision Event Timer
that is supposed to supplement and eventually replace the 8254 timer and
the RTC periodic interrupts. Among other things, it is 64 bit (can be
run in 32 bit mode for 32 bit cpus), and is suitable as a replacement for
the ACPI timer on SMP systems (the specs are much better) and as a
replacement for the ITC based synthetic clock for on ia64 systems.
It seems IA64 and AMD64 systems tend to have this. It is likely to start
showing up in i386 systems if it isn't already on some of them.

o Extend struct ACPIrsdp with the ACPI 2.0 fields which involves
changing a prior reserved field into the ACPI revision,
o Only calculate the RSDP checksum on the first 20 bytes to remain
compatible with ACPI 1.0 tables; we don't check the extended
checksum covering the whole table,
o Use the length field in the RSDP to map the RSDP into the address
space so that we don't have to know about future extensions here.

- Merge AML parser to build ACPI namespace
- Comment header info. out so that ASL compiler ignore them
- Fix DSDT header size to be discarded when DSDT file is specified
for input (acpidump and amldb)
- Write DSDT header as well into DSDT file for output
- Fix some trivial typo (Concatenate and SizeOf)
- Remove DEBUG_FLAGS from Makefile (acpidump and amldb)
Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.
