Rebase qemu-android over upstream QEMU v2.7.0

This patch rebases the qemu-android source base
on top of a much more recent version of upstream
QEMU (previous version was 2.2.0).

It was created by doing the following:

- Look at the history of all changes in qemu-android
  over v2.2.0, and "clean it up" into a list of
  small opiniated patches to do one of the following:

    - port back fixes from upstream that happened
      after v2.2.0

    - provide bug-fixes / improvements required
      by the Android emulator (but not directly
      related for Android emulation).

    - add Android-specific features.

- Rebase the "clean patches stack" on top of
  QEMU v2.7.0 (i.e. 1dc33ed90bf). The end process
  ended up being one of this patch's parents,
  i.e. 41b9dc407

- Merge the latter with the 'theirs' strategy
  (favoring the new sources over the current ones).

- Manually adjust any required changes by
  comparing the state of both trees. Fix any
  remaining conflicts.

NOTE: This updates the git submodule for the dtc/
      sub-directory, you may need to run the
      following command in your work directory
      after pulling this change:

         git submodule update dtc

  * you may assume that integers are 2s complement representation
  * you may assume that right shift of a signed integer duplicates
    the sign bit (ie it is an arithmetic shift, not a logical shift)
+
+In addition, QEMU assumes that the compiler does not use the latitude
+given in C99 and C11 to treat aspects of signed '<<' as undefined, as
+documented in the GNU Compiler Collection manual starting at version 4.0.
+
+7. Error handling and reporting
+
+7.1 Reporting errors to the human user
+
+Do not use printf(), fprintf() or monitor_printf().  Instead, use
+error_report() or error_vreport() from error-report.h.  This ensures the
+error is reported in the right place (current monitor or stderr), and in
+a uniform format.
+
+Use error_printf() & friends to print additional information.
+
+error_report() prints the current location.  In certain common cases
+like command line parsing, the current location is tracked
+automatically.  To manipulate it manually, use the loc_*() from
+error-report.h.
+
+7.2 Propagating errors
+
+An error can't always be reported to the user right where it's detected,
+but often needs to be propagated up the call chain to a place that can
+handle it.  This can be done in various ways.
+
+The most flexible one is Error objects.  See error.h for usage
+information.
+
+Use the simplest suitable method to communicate success / failure to
+callers.  Stick to common methods: non-negative on success / -1 on
+error, non-negative / -errno, non-null / null, or Error objects.
+
+Example: when a function returns a non-null pointer on success, and it
+can fail only in one way (as far as the caller is concerned), returning
+null on failure is just fine, and certainly simpler and a lot easier on
+the eyes than propagating an Error object through an Error ** parameter.
+
+Example: when a function's callers need to report details on failure
+only the function really knows, use Error **, and set suitable errors.
+
+Do not report an error to the user when you're also returning an error
+for somebody else to handle.  Leave the reporting to the place that
+consumes the error returned.
+
+7.3 Handling errors
+
+Calling exit() is fine when handling configuration errors during
+startup.  It's problematic during normal operation.  In particular,
+monitor commands should never exit().
+
+Do not call exit() or abort() to handle an error that can be triggered
+by the guest (e.g., some unimplemented corner case in guest code
+translation or device emulation).  Guests should not be able to
+terminate QEMU.
+
+Note that &error_fatal is just another way to exit(1), and &error_abort
+is just another way to abort().

+         QEMU README
+         ===========
 
-- QEMU team
+QEMU is a generic and open source machine & userspace emulator and
+virtualizer.
+
+QEMU is capable of emulating a complete machine in software without any
+need for hardware virtualization support. By using dynamic translation,
+it achieves very good performance. QEMU can also integrate with the Xen
+and KVM hypervisors to provide emulated hardware while allowing the
+hypervisor to manage the CPU. With hypervisor support, QEMU can achieve
+near native performance for CPUs. When QEMU emulates CPUs directly it is
+capable of running operating systems made for one machine (e.g. an ARMv7
+board) on a different machine (e.g. an x86_64 PC board).
+
+QEMU is also capable of providing userspace API virtualization for Linux
+and BSD kernel interfaces. This allows binaries compiled against one
+architecture ABI (e.g. the Linux PPC64 ABI) to be run on a host using a
+different architecture ABI (e.g. the Linux x86_64 ABI). This does not
+involve any hardware emulation, simply CPU and syscall emulation.
+
+QEMU aims to fit into a variety of use cases. It can be invoked directly
+by users wishing to have full control over its behaviour and settings.
+It also aims to facilitate integration into higher level management
+layers, by providing a stable command line interface and monitor API.
+It is commonly invoked indirectly via the libvirt library when using
+open source applications such as oVirt, OpenStack and virt-manager.
+
+QEMU as a whole is released under the GNU General Public License,
+version 2. For full licensing details, consult the LICENSE file.
+
+
+Building
+========
+
+QEMU is multi-platform software intended to be buildable on all modern
+Linux platforms, OS-X, Win32 (via the Mingw64 toolchain) and a variety
+of other UNIX targets. The simple steps to build QEMU are:
+
+  mkdir build
+  cd build
+  ../configure
+  make
+
+Complete details of the process for building and configuring QEMU for
+all supported host platforms can be found in the qemu-tech.html file.
+Additional information can also be found online via the QEMU website:
+
+  http://qemu-project.org/Hosts/Linux
+  http://qemu-project.org/Hosts/W32
+
+
+Submitting patches
+==================
+
+The QEMU source code is maintained under the GIT version control system.
+
+   git clone git://git.qemu-project.org/qemu.git
+
+When submitting patches, the preferred approach is to use 'git
+format-patch' and/or 'git send-email' to format & send the mail to the
+qemu-devel@nongnu.org mailing list. All patches submitted must contain
+a 'Signed-off-by' line from the author. Patches should follow the
+guidelines set out in the HACKING and CODING_STYLE files.
+
+Additional information on submitting patches can be found online via
+the QEMU website
+
+  http://qemu-project.org/Contribute/SubmitAPatch
+  http://qemu-project.org/Contribute/TrivialPatches
+
+
+Bug reporting
+=============
+
+The QEMU project uses Launchpad as its primary upstream bug tracker. Bugs
+found when running code built from QEMU git or upstream released sources
+should be reported via:
+
+  https://bugs.launchpad.net/qemu/
+
+If using QEMU via an operating system vendor pre-built binary package, it
+is preferable to report bugs to the vendor's own bug tracker first. If
+the bug is also known to affect latest upstream code, it can also be
+reported via launchpad.
+
+For additional information on bug reporting consult:
+
+  http://qemu-project.org/Contribute/ReportABug
+
+
+Contact
+=======
+
+The QEMU community can be contacted in a number of ways, with the two
+main methods being email and IRC
+
+ - qemu-devel@nongnu.org
+   http://lists.nongnu.org/mailman/listinfo/qemu-devel
+ - #qemu on irc.oftc.net
+
+Information on additional methods of contacting the community can be
+found online via the QEMU website:
+
+  http://qemu-project.org/Contribute/StartHere
