Alexander Graf 77a8f1a512 linux-user: Fix stale tbs after mmap
If we execute linux-user code that does the following:

  * A = mmap()
  * execute code in A
  * munmap(A)
  * B = mmap(), but mmap returns the same address as A
  * execute code in B

we end up executing a stale cached tb that contains translated code
from A, while we want new code from B.

This patch adds a TB flush for mmap'ed regions, before we return them,
avoiding the whole issue. It also adds a flush for munmap, so that we
don't execute stale TBs instead of getting a segfault.

Alexander Graf 1a49ef2ad3 linux-user: fix emulation of /proc/self/maps
Improve the emulation of /proc/self/maps by reading the underlying
host maps file and passing lines through with addresses adjusted
to be guest addresses. This is necessary to avoid false triggers
of the glibc check that a format string containing '%n' is not in
writable memory. (For an example see the bug reported in
https://bugs.launchpad.net/qemu-linaro/+bug/947888 where gpg aborts.)

Paul Brook d8fd295499 Userspace ARM BE8 support
Add support for ARM BE8 userspace binaries.
i.e. big-endian data and little-endian code.
In principle LE8 mode is also possible, but AFAIK has never actually
been implemented/used.

System emulation doesn't have any useable big-endian board models,
but should in principle work once you fix that.
Dynamic endianness switching requires messing with data accesses,
preferably with TCG cooperation, and is orthogonal to BE8 support.

When calling wait4 or waitpid with a status pointer and WNOHANG, the
syscall can potentially not modify the status pointer input. Now if we
have guest code like:

  if (status)

then we have to make sure that in case status did not change we actually
return the guest's initialized status variable instead of our own uninitialized.

variable which for me ended up always containing the last error code.
