OABI.

getgroups() returns the number of supplementary group IDs, so it's
unnessary to swap the entire array. It can dramatically speed up
the syscall: on recent Linux kernels NGROUPS_MAX=65536.

According to linux kernel sources, register a3 is set in case of failure
(and cleared in case of success) while register v0 contains the result
(or -errno in case of error).
The convention was not followed which results in weird behaviour.

* Remove the unused send_buf variable and its constant.
* Fix a math error
The variables recv_ptr and recv_used are not large enough to hold
the constant 384, which causes data corruption when the pointer is

The "Rx timeout" (aka. Character Timeout Indication) has no separate mask
bit in the IER register and according to the specs reading RHR is the only
way to reset the irq. However on the hardware (tested on OMAP2 UART which
is an extended 16550A) the RHR_IT bit in IER disables the irc, too. Linux
bluetooth serial dongle driver for N800 depends on this behavior.

The protocol_name "file" was added to the block driver when async IO was
introduced. This can be used to select that a file is treated as a raw
device instead of probing for the type. However, protocols are not subject
to path interpretation which cases qcow2 images with raw base images to not
function is the path was specified relatively.
The fix is simply to remove the protocol_name from the raw block driver. The
proper way to force the use of a raw block format is to use the format= option
with -drive.

On some cases, such as under KVM, tb_invalidate_phys_page_range()
may be called for large addresses, when qemu is configured to more than
4GB of RAM.
On these cases, qemu was crashing because it was using an index too
large for l1_map[], that supports only 32-bit addresses when compiling
without CONFIG_USER_ONLY.

Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the
code. It's ugly and causes us to have to build multiple object files for
linking against qemu and the tools.
This patch introduces a new file, qemu-tool.c which contains enough for
qemu-img, qemu-nbd, and QEMU to all share the same objects.
This also required getting qemu-nbd to be a bit more Windows friendly. I also
changed the Windows block-raw to use normal IO instead of overlapping IO since
we don't actually do AIO yet on Windows. I changed the various #if 0's to
#if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows.
After this patch, there are no longer any #ifdef's related to qemu-img and
qemu-nbd.
