[ Taking latest isapc changes into account. ]
Ensure that PIC-delivered IRQs are properly de-asserted in case the APIC
is in EXTINT or FIXED mode (with level-triggering selected) on LINT0.
Fixes EFI-BIOS boot issues.
This patch also cleans up a bit the interface between PIC and APIC,
making apic_local_deliver private again.

[ Taking latest isapc changes into account. ]
In case the PIC IRQ gets de-asserted on an isapc machine, we also have
to reset CPU_INTERRUPT_HARD. This is what older qemu (before the
routing-through-APIC changes) used to do as well.

Some headers (e.g. signal.h) include asm/elf.h and the chaos of macro
redefinitions ensues, this kludge avoids it.
Alternative way to fight that would be to change all ELF_XXX and some
other definitions to QEMU_ELF_XXX or something to that effect.
This patch concludes the quest for enabling linux-user on PPC64,
however, since qemu_mallocz uses mmap and, at least on this system,
mmap tends to return values that do not fit into 32bit, emulation for
32bit targets does not work without some hacks wich are to disgusting
to commit (and as `man mmap' tells us MAP_32BIT is only implemented on
X86_64)

p in this case is uint32_t *
e1/e2 are unsigned ints initialized from arithmetics performed on
unsigned longs
The mistake was, probably, never noticed due to the absence of any
big endian linux-user host. The types e1/e2 and p begs the quesiton
why this function takes longs at all.

According to ACPI spec table 4-13 suspend type field should be 3 bits

Add SEEK_STAT in all non-error cases except sleep request, since our

in some case if we do not set it.

This patch upgrades the emulated UART to 16550A, the code comes from
xen-unstable. The main improvement was introduced with the following patch and
subsequent email thread:
http://lists.xensource.com/archives/html/xen-devel/2007-12/msg00129.html
The changes compared to previous version are:
- change clock_gettime to qemu_get_clock
- no token bucket anymore;
- fixed a small bug handling IRQs; this was the problem that prevented
kgdb to work over the serial (thanks to Jason Wessel for the help
spotting and reproducing this bug).
- many many style fixes;
- savevm version number increased;
- not including termios.h and sys/ioctl.h anymore, declaring static
constants in qemu-char.h instead;
