linux-user: Split linux-user internals out of qemu.h

qemu.h is included in various non-linux-user files (which
mostly want the TaskState struct and the functions for
doing usermode access to guest addresses like lock_user(),
unlock_user(), get_user*(), etc).

Split out the parts that are only used in linux-user itself
into a new user-internals.h. This leaves qemu.h with basically
three things:
* the definition of the TaskState struct
* the user-access functions and macros
* do_brk()
all of which are needed by code outside linux-user that
includes qemu.h.

The addition of all the extra #include lines was done with
sed -i '/include.*qemu\.h/a #include "user-internals.h"' $(git grep -l 'include.*qemu\.h' linux-user)
(and then undoing the change to fpa11.h).

linux-user/s390x: Save and restore psw.mask properly

linux-user/s390x: Save and restore psw.mask properly

At present, we're referencing env->psw.mask directly, which
fails to ensure that env->cc_op is incorporated or updated.
Use s390_cpu_{set_psw,get_psw_mask} to fix this.

Mirror the kernel's cleaning of the psw.mask in save_sigregs
and restore_sigregs. Ignore PSW_MASK_RI for now, as qemu does
not support that.
