e281c2bafe linux-user/cris: Implement setup_sigtramp
Split out setup_sigreturn so that we can continue to
initialize the words on the stack, as documented.
However, use the off-stack trampoline.

3b249d2661 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).

8f0ea81643 linux-user: Do not report "syscall not implemented" by default
This can still be reported using the "-d unimp" command line option.

Code change produced with:

  git ls-files linux-user | \
  xargs sed -i -E 's/fprintf\(stderr,\s?(".*not implemented\\n")\);/qemu_log_mask(LOG_UNIMP, \1);/g'
