The hassle and compile time overhead of maintaining both 32-bit and 64-bit
capable source isn't worth the tiny performance advantage which is seen on
a minority of configurations. Switch to compiling libhw only once, with
target_phys_addr_t unconditionally typedefed to uint64_t.

Define a set of TARGET_PRI*PHYS format specifier macros for working
with target_phys_addr_t types. These follow the standard pattern
for such macros, and are more flexible than TARGET_FMT_plx, which
does not allow specification of field widths.

Historically the qemu tlb "addend" field was used for both RAM and IO accesses,
so needed to be able to hold both host addresses (unsigned long) and guest
physical addresses (target_phys_addr_t). However since the introduction of
the iotlb field it has only been used for RAM accesses.
This means we can change the type of addend to unsigned long, and remove
associated hacks in the big-endian TCG backends.
We can also remove the host dependence from target_phys_addr_t.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

Some not so obvious bits, slirp and Xen were left alone for the time
being.

As Avi correctly noted, last_ram_offset does not mark the last physical
RAM address the guest may see (due to non-continuous memory regions).
Ensure that we catch them all by marking the full possible address range
dirty.

The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.
Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.
Big/Little endian is not handled because devices should not know or care
about this to start with.
