This patch implements a simple fd pool to allow many AIO requests with posix-aio. The result is significantly improved performance (identical to that reported for linux-aio) for both cache=on and cache=off. The fundamental problem with posix-aio is that it limits itself to one thread per-file descriptor. I don't know why this is, but this patch provides a simple mechanism to work around this (duplicating the file descriptor). This isn't a great solution, but it seems like a reasonable intermediate step between posix-aio and a custom thread-pool to replace it. Ryan Harper will be posting some performance analysis he did comparing posix-aio with fd pooling against linux-aio. The size of the posix-aio thread pool and the fd pool were largely determined by him based on this analysis.

__GLIBC_PREREQ is defined in such a way that the ! cannot be used in front of it on FreeBSD. Also, -lpthread is not implied by the build and we definitely use it for compatfd support. While at it, I added a default initialization for posix-aio that seems to perform well in our testing.

During the debugging of the new revision of the zero dedup patch I stepped on the following bug in block-qcow2.c:alloc_cluster_offset(). I am not sure what the exact damage this bug can do, but it may be very nasty because you way not notice it effects until you will do some snapshot operations or similar actions that rely on the reference counting. The bug is easy to spot using the new "check" verb I added to the qemu-img in one of the previous patches. I will resend the qemu-img patch again with the new version of the zero dedup.

This patch allows to use a "real" SCSI tape with qemu using "-drive /dev/sgX,if=scsi". It allows to decode correctly transfer length when the type of the device is a tape. Some issues remain when the application reading the tape tries to go beyond the end of the stream (but they must be corrected at the SCSI controller level).

This patch refactors the AIO layer to allow multiple AIO implementations. It's only possible because of the recent signalfd() patch. Right now, the AIO infrastructure is pretty specific to the block raw backend. For other block devices to implement AIO, the qemu_aio_wait function must support registration. This patch introduces a new function, qemu_aio_set_fd_handler, which can be used to register a file descriptor to be called back. qemu_aio_wait() now polls a set of file descriptors registered with this function until one becomes readable or writable. This patch should allow the implementation of alternative AIO backends (via a thread pool or linux-aio) and AIO backends in non-traditional block devices (like NBD).

Raise UDC (Unexpected Disconnect) when a large enough number of instructions has been executed by the SCRIPTS processor. This "solution" is much simpler than temporarily interrupting execution. This remedies the situation with Windows which downloads SCRIPTS code that busy loops on guest main memory. Their drivers _do_ handle UDC appropriately (at least XP and 2003). It would be nicer to actually detect infinite loops, but until then, this bandaid seems acceptable. Since the situation seems to be rare enough, raise the number of instructions to 10000 (previously 1000). Three people other than myself had success with this patch.
