b67c567b79 accel/tcg: Return bool from TranslatorOps.disas_log 
We have eliminated most uses of this hook.  Reduce
further by allowing the hook to handle only the
special cases, returning false for normal processing.

66f3b79e85 accel/tcg: Hide in_same_page outside of a target-specific context 
While there are other methods that could be used to replace
TARGET_PAGE_MASK, the function is not really required outside
the context of target-specific translation.

This makes the header usable by target independent code.

69e78f1b34 system/physmem: Per-AddressSpace bounce buffering 
Instead of using a single global bounce buffer, give each AddressSpace
its own bounce buffer. The MapClient callback mechanism moves to
AddressSpace accordingly.

This is in preparation for generalizing bounce buffer handling further
to allow multiple bounce buffers, with a total allocation limit
configured per AddressSpace.
