struct kvm_userspace_memory_region does not use QEMU friendly types to

This patch introduces a proper KVMSlot structure that uses QEMU types to

This patch tweaks the ATAPI CDROM emulation to fix an annoyance seen
when running a variety of Linux guests: the desktop GUI shows a CDROM
device as present, but is unable to automount the media and display its
contents.
The patch adds the PLAY_AUDIO capability bit to the data returned by
MODE_SENSE commands. That convinces the guest kernel to determine what
kind of media is present.
Arguably Linux could be smarter about this, but it's my guess there are
few (if any) hardware CDROM drives that don't set the bit, and there are
a large number of Linux distros that exhibit this problem.

This patch enhances QEMU's built-in debugger for SMP guest debugging.
Using the thread support of the gdb remote protocol, each VCPU is mapped
on a pseudo thread and exposed to the gdb frontend. This way you can
easy switch the focus of gdb between the VCPUs and observe their states.
On breakpoint hit, the focus is automatically adjusted just as for
normal multi-threaded application under gdb control.
Furthermore, the patch propagates breakpoint and watchpoint insertions
or removals to all CPUs, not just the current one as it was the case so
far. Without this, SMP guest debugging was practically unfeasible.

This patch prepares the QEMU cpu_watchpoint/breakpoint API to allow the
succeeding enhancements this series comes with.
First of all, it overcomes MAX_BREAKPOINTS/MAX_WATCHPOINTS by switching
to dynamically allocated data structures that are kept in linked lists.
This also allows to return a stable reference to the related objects,
required for later introduced x86 debug register support.
Breakpoints and watchpoints are stored with their full information set
and an additional flag field that makes them easily extensible for use
beyond pure guest debugging.

This patch implemented the setxuid and setxgid syscalls for Alpha.
These syscalls return two values, both uid/euid and gid/egid.
In addition to returning the first value in $v0, the additional
value is returned in the $a4 register.
The syscalls are used instead of the separate syscalls for those values
used on other architectures (this is probably because Alpha Linux started
out syscall compatible with DEC/OSF/Tru64).
With this patch, the perlbmk benchmarks from Spec2000 run properly.
