      Clean up includes so that osdep.h is included first and headers
      which it implies are not included manually.

      translate-all: ensure host page mask is always extended with 1's · 0c2d70c4
      Paolo Bonzini authored
      Anthony reported that >4GB guests on Xen with 32bit QEMU broke after
      commit 4ed023ce ("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.
