Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.
This commit was created with scripts/clean-includes.

Anthony reported that >4GB guests on Xen with 32bit QEMU broke after
commit 4ed023c ("Round up RAMBlock sizes to host page sizes", 2015-11-05).
In that patch sizes are masked against qemu_host_page_size/mask which
are uintptr_t, and thus 32bit on a 32bit QEMU, even though the ram space
might be bigger than 4GB on Xen.
Since ram_addr_t is not available on user-mode emulation targets, ensure
that we get a sign extension when masking away the low bits of the address.
Remove the ~10 year old scary comment that the type of these variables
is probably wrong, with another equally scary comment. The new comment
however does not have "???" in it, which is arguably an improvement.
For completeness use the alignment macros in linux-user and bsd-user
instead of manually doing an &. linux-user and bsd-user are not affected
by the Xen issue, however.

Move the size and mask globals for the "real" host page size to
translate-common. This is to allow system-level code to use
REAL_HOST_PAGE_ALIGN and friends in builds which hide translate-all
behind arch-obj.

Move this function to common code. It has no arch specific
dependencies. Prepares support for multi-arch where the translate-all
interface needs to be virtualised. One less thing to virtualise.
