Move dma code to new file hw/dma.c.
Move the DMA controller code in resume.c and hw/floppy.c to a new file
hw/dma.c. This centralizes the DMA controller code into one place.
Also, don't unmask the floppy DRQ during floppy setup - there is no
reason to unmask the DRQ prior to a command being programmed into the
DMA controller.

This patch simplifies seabios cross-builds on !x86 platforms.
It adds a CROSS_PREFIX variable which is used to set CC, LD &
friends to the cross build binaries. It also moves the common
command definitions up in the Makefile to make sure CC is set
correctly when probing compiler flags using $(call cc-option ...)
Recent git versions place the submodule git repos into the
.git/modules directory of the toplevel repo. In that case
.git of the seabios tree isn't a directory, but a regular
file, saying where the gitdir is.
Extent the git check to also allow .git being a regular file,
so buildversion.sh works correctly when called within the qemu
submodule.

usb: add xhci support
$subject says all. Support for usb3 streams is not implemented yet,
otherwise it is fully functional. Tested all usb devices supported
by qemu (keyboard, storage, usb hubs), except for usb attached scsi
in usb3 mode (which needs streams).
Tested on qemu only, tagged with QEMU_HARDWARE because of that.
Testing with physical hardware to be done.
This patch adds support for detecting whenever SeaBIOS runs on qemu
or not. This is done by looking at the northbridge (pci device 00:00.0)
and check the subsystem id. Most pci devices emulated by qemu -- the
two northbridges i440fx and q35 included -- have a subsystem id of
"1af4:1100".
In case the subsystem ID matches set PF_QEMU, log a message (including
the northbridge found while being at it) and also check for kvm.

Rename tools/ directory to scripts/ directory.
It's common for other projects (eg, QEMU, Linux) to put build scripts
into a "scripts/" directory. There's no reason for SeaBIOS to be
different, so rename the "tools/" directory to "scripts/".

Add config option to support memory allocations in 9-segment.
Internal "low memory" allocations are currently placed in the UMB
region (0xc0000-0xf0000). However, there have been reports of some
real machines that do not support DMA to this area of memory. So, add
a compile time config option (off by default) to support placing all
internal low-memory allocations at the end of the 640K real-memory
area (0x90000-0xa0000).

Qemu commit 9ee59f3 removed the bochs bios apm interface emulation at
port 0x8900. That broke poweroff via APM. Fix it by powering off the
machine using the acpi pm control register.
Old code is left in, so seabios wil try both poweroff methods. Cleaning
that eventually up is left for another patch, after checking it isn't
needed. Qemu never implemented "Standby" and "Suspend", only
"Shutdown", so it looks like there might be non-qemu use cases (bochs
probably).
Easiest way to test this is the syslinux poweroff module; modern linux
distros usually have CONFIG_APM turned off.

Default unused UMB areas to be read-only.
It looks like MSDOS 6 wants the UMB area to be read-only in order for
it to use it. FreeDOS doesn't care, but it always maps a page from
high mem when it does use the area. So, add an option to control
whether unused UMB ram is marked read-only and default it to read-only
as that seems to be more compatible.
This also fixes an off-by-one bug in the shadow range checking code.

Improve accuracy of internal timers.
The TICKS_PER_DAY setting is a bios standard and needs to be 1573040
for compatibility. However, there are actually ~1573042.24 ticks in a
day. So, only use TICKS_PER_DAY when working with the BDA
timer_counter - not when calculating any internal times.
The PIT hz is actually 143181800 / 12 (~1193181.667). This can be
accurately encoded as PMTIMER hz / 3. Because the PIT hz is usually
multiplied and divided by other numbers, we can use the PMTIMER hz and
defer the division by 3 to improve accuracy.
When doing division for delay time calculations, always round up the
division so the delay is never less than the requested time.
