[PATCH 01/11] softmmu: Introduce qemu_target_page_mask/qemu_target_page_align helpers

[Philippe Mathieu-Daudé]

Since TARGET_PAGE_MASK and TARGET_PAGE_ALIGN are poisoned in
target-agnostic code, introduce the qemu_target_page_mask()
and qemu_target_page_align() helpers to get these values from
target-agnostic code at runtime.
