  Enable 8-byte wide MMIO for 16550 serial devices

Some drivers for the PPMC7400 PowerPC evaluation board accesses the
serial registers through the floating point unit (stfd/ldfd), which is
an 8-byte wide access. This patch enables that behavior.

  ioapic/tracing: Remove last DPRINTFs

Remove the last few DPRINTFs from hw/intc/ioapic.c and turn
them into tracing.  In one case it's a new trace, in the others
it's just adding a parameter to the existing traces.

  Makefile: simpler/faster "make help"

Using obscure black magic introduced in eaa2ddbb767 :)

In an out-of-tree directory, running "../configure && make help" will generate
some required files (.mak), then clone some submodules, compile at least
the capstone submodule, generate QMP and Trace files, and finally display
the help.

On an outdated computer (Sun Blade workstation), running "make help" took
more than 5h :) With this patch it took roughly 37min.

  vhost-user-scsi: add missing virtqueue_size param

Commit 5c0919d0 [1] introduced virtqueue_size parameter
for common virtio-scsi path, without updaing the vhost-user-scsi
code. vhost-user-scsi devices right now report size 0 for each vq.

This patch introduces virtqueue_size param to vhost-user-scsi,
that can now be set by the user. However, the most importantly, it
now has a default value of 128 (same as QEMU's virtio-scsi).

[1] 5c0919d0 ("virtio-scsi: Add virtqueue_size parameter
allowing virtqueue size to be set.")

  cpu-exec: avoid cpu_exec_nocache infinite loop with record/replay

This patch ensures that icount_decr.u32.high is clear before calling
cpu_exec_nocache when exception is pending.  Because the exception is
caused by the first instruction in the block and it cannot be executed
without resetting the flag.

There are two parts in the fix.  First, clear icount_decr.u32.high in
cpu_handle_interrupt (just before processing the "dependent" request,
stored in cpu->interrupt_request or cpu->exit_request) rather than
cpu_loop_exec_tb; this ensures that cpu_handle_exception is always
reached with zero icount_decr.u32.high unless another interrupt has
happened in the meanwhile.

Second, try to cause the exception at the beginning of
cpu_handle_exception, and exit immediately if the TB cannot
execute.  With this change, interrupts are processed and
cpu_exec_nocache can make process.

  exec: Do not resolve subpage in mru_section

This fixes a crash caused by picking the wrong memory region in
address_space_lookup_region seen with client code accessing a device
model that uses alias memory regions.  The expensive part of
address_space_lookup_region anyway is phys_page_find; performance-wise
it is okay to repeat the subsequent subpage lookup.
