The page tracking code in exec.c is used by both userspace and system
emulation.  Userspace emulation uses it to track virtual pages, and
system emulation to track ram pages.  Introduce a new type to hold this
kind of address.

The addr < end comparison prevents iterating over the last
page in the guest address space; an iteration based on
length avoids this problem.

At the same time, assert that the given address is in the
guest address space.

Define L1_MAP_ADDR_SPACE_BITS to be either the virtual address size
(in user mode) or physical address size (in system mode), and use
that to size l1_map.  This rewrites page_find_alloc, page_flush_tb,
and walk_memory_regions.

Use TARGET_PHYS_ADDR_SPACE_BITS for the physical memory map based
off of l1_phys_map.  This rewrites page_phys_find_alloc and
phys_page_for_each.

Don't return addresses that aren't properly aligned for the guest,
e.g. when the guest has a larger page size than the host.  Don't
return addresses that are outside the virtual address space for the
target, by paying proper attention to the h2g/g2h macros.

At the same time, place the default mapping base for 64-bit guests
(on 64-bit hosts) outside the low 4G.  Consistently interpret
mmap_next_start in the guest address space.

Previously, only 32-bit guests had a proper check for the
validity of the virtual address.  Extend that check to 64-bit
guests with a restricted virtual address space.

Removes a set of ifdefs from exec.c.

Introduce TARGET_VIRT_ADDR_SPACE_BITS for all targets other
than Alpha.  This will be used for page_find_alloc, which is
supposed to be using virtual addresses in the first place.

Something bad has happened in the merge of commit 0ee44250, as
the log message says it's supposed to be in qemu_system_reset()
but it is do_vm_stop().

Possibly, it was a problem with the conflict resolution with
ea375f9a (which has been merged first).

This commit moves (again) the RESET event into qemu_system_reset().

A SIB byte with an index of 4 means "no scaled index", even if the scale
value is not 0. In 64-bit mode, if REX.X is used, an index of 4 selects
%r12. This is correctly handled by the computation of the index variable,
which includes the index bits, and also the REX.X prefix:

    index = ((code >> 3) & 7) | REX_X(s);

Thanks to Avi Kivity, Jamie Lokier and Malc for the analysis of the
problem and the initial patch.

These files are created by configure and grow
unnecessarily at each new call of configure:

roms/seabios/config.mak
roms/vgabios/config.mak
libhw32/config.mak
libhw64/config.mak

libhw32/config.mak and libhw64/config.mak set
compiler options, and the wrong old code results
in very long command lines.

The new code always writes a new config.mak
instead of appending to an existing one.
