Since previous commit, tb_invalidate_phys_page() is not used
anymore in system emulation. Make it static for user emulation
and remove its public declaration in "exec/translate-all.h".

The only thing that still touches PageDesc in translate-all.c
are some locking routines related to tb-maint.c which have not
yet been moved. Do so now.
Move some code up in tb-maint.c as well, to untangle the maze
of ifdefs, and allow a sensible final ordering.
Move some declarations from exec/translate-all.h to internal.h,
as they are only used within accel/tcg/.

This function is is never called with a real range,
only for a single page. Drop the second parameter
and rename to tb_invalidate_phys_page.

translate_insn() implementations fetch instruction bytes piecemeal,
which can cause qemu-user to generate inconsistent translations if
another thread modifies them concurrently [1].
Fix by making pages containing translated instruction non-writable
right before loading instruction bytes from them.

Enable removing tcg/$tcg_arch from the include path when TCG is disabled.
Move translate-all.h to include/exec, since stubs exist for the functions
defined therein.
