Usually the guest can tell the host to flush data to disk. In some cases we
don't want to flush though, but try to keep everything in cache.
So let's add a new cache value to -drive that allows us to set the cache
policy to most aggressive, disabling flushes. We call this mode "unsafe",
as guest data is not guaranteed to survive host crashes anymore.
This patch also adds a noop function for aio, so we can do nothing in AIO
fashion.

- two pairs of softmmu indexes bind softmmu tlb to cpu tlb in fault handlers
using value of DMMU primary and secondary context registers, so we need to

- cpu_mmu_index return MMU_NUCLEUS_IDX if trap level is not zero
- cpu_get_tb_cpu_state: store trap level and primary context in flags
this allows to restart code translation when address translation is changed
- stop translation block after writing to pstate and tl registers
- stop translation block after writing to alternate space
this can be optimized to stop only if address translation can be changed
by write operation (e.g. by comparing with MMU ASI values)

The 'tarbin' Makefile rule doesn't include qemu-system-sparc64, but
should do, now that sparc64-softmmu is in the default target list.
The rule attempts to tar up binaries that were not built if a target
list was passed to the configure script -- in which case, it will
either fail, or otherwise include binaries from previous builds.
Fix both problems once and for all by building a list of binaries to
include in the tarball, using the list of targets to be built.

This seems to resolve subtle breakages of our build system:
Dependency files generated for targets like 'dir/foo.o' were saved as
'foo.d'. Now, if there was also a target 'foo.o', one of the dependency
file was overwritten. Concrete example: libhw*/macio.o vs.
libhw*/ide/macio.o. And this often left a segfaulting build result
behind when changing the "wrong" data structures".
Fix it by generating proper 'dir/foo.d'.

Alpha passes oldset by value in a register, and returns the newset
as the return value; as compared to the standard implementation in
which both are passed by reference. This requires being able to
distinguish negative return values that are not errors. Do this in
the same way as the Alpha Linux kernel, by storing a zero in V0 in
the implementation of the syscall.
At the same time, fix a think-o in the regular sigprocmask path in
which we passed the target, rather than the host, HOW value.
