The original SoftFloat 2.0b library avoided the use of custom integer types
in its public headers. This requires the definitions of int{8,16,32,64} to
match the assumptions in the declarations. This breaks on BeOS R5 and Haiku/x86,
where int32 is defined in {be,os}/support/SupportDefs.h in terms of a long
rather than an int. Spotted by Michael Lotz.
Since QEMU already breaks this distinction by defining those types just above,
do use them for consistency and to allow #ifndef'ing them out as done for
[u]int16 on AIX.

The PCI/PCI-X Family of Gigabit Ethernet Controllers Software
Developer’s Manual states the following about the POPTS field:
Provides a number of options which control the handling of this
packet. This field is ignored except on the first data descriptor of
a packet.
The current implementation always loads the field and its checksum
offload flags. This patch uses only the first descriptor's POPTS field
in order to comply with the specification.
When Solaris sends multi-descriptor packets it fills in POPTS for the
first descriptor only. Therefore this patch is necessary in order to
perform checksum offload correctly for multi-descriptor packets.

Add support for the Versatile Express SYS_CFG registers, which provide
a generic means of reading or writing configuration information from
various parts of the board. We only implement shutdown and reset.
Also make the RESETCTL register RAZ/WI on Versatile Express rather
than reset the board. Other system registers are generally the same
as Versatile and Realview.
This includes a VMState version number bump for arm_sysctl,
since we have new register state to preserve. It also adds
sys_mci to the VMState while we're bumping the version number
(an accidental omission from commit b50ff6f5).

These patches are already not doing a great service to out-of-tree

This enables rt_clock timers to use nanosecond resolution, just by
using the _ns functions; there is really no reason to forbid that.
Migrated timers are all using vm_clock (of course; but I checked that
anyway) so the timers in the savevm files are already in nanosecond
resolution. So this patch makes no change to the migration format.

This was done with:

after checking that get_clock and new_timer never occur twice
on the same line. There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.
There was exactly one false positive in qemu_run_timers:
- current_time = qemu_get_clock (clock);

This patch fixes two things:

offline. Error is now explicitly set to zero.
2) SMART
The smart values that were returned were invalid and tools like skdump
would not recognize that the smart data was actually valid and would
dump weird output. The data has been fixed up and raw value support
was added. Tools like skdump and palimpsest work as expected.

It's wrong to call BHs directly, even in tools. The only operations that
schedule BHs are called in a loop that (indirectly) contains a call to
qemu_bh_poll anyway, so we're not losing the scheduled BHs: Tools either use
synchronous functions, which are guaranteed to have completed (including any
BHs) when they return; or if they use asynchronous functions, they need to call
qemu_aio_wait() or similar functions already today.
