spapr: add vio-bus devices to categories

In order to get devices appear in output of
"./qemu-system-ppc64 -device ?",
they must be assigned to one of DEVICE_CATEGORY_XXXX.

This puts VIO devices classes to corresponding categories.

qemu-char: add support for U-prefixed symbols

This patch adds support for Unicode symbols in keymap files. This
feature was already used in some keyboard layouts in QEMU generated
from XKB (e.g. Arabic) but it wasn't implemented in QEMU source code.

There is no need for check of validity of the hex string after U character
because strtol returns 0 in case the conversion was unsuccessful.

qemu-char: add missing characters used in keymaps

This patch adds all missing characters used in regional keymap
files which already exist in QEMU. I checked for the missing
characters by going through all of the keymaps and matching that
with records in vnc_keysym.h. If the key wasn't found I looked
it up in libxkbcommon library [1]. If I understood it correctly
this is also the same place where most of the keymaps were
exported from according to the comment on the first line in those
files. I was able to find all symbols except "quotebl" used
in Netherland keymap.

I tested this update with Czech keyboard by myself. I also asked
Matej Serc to test Slovenian keyboard layout - he reported problems
with it few days ago on this mailing list. Both layouts seems
to work fine. I wasn't able to test the remaining layouts but
since this change doesn't modify any existing symbols, just adds
new ones, I don't expect any sideeffects.

pci-assign: Fix error_report of pci-stub message

Using multiple calls to error_report here means every line is
prefaced with the (potentially long) pci-assign command line
arguments.

Use a single error_printf to preserve the intended formatting.
Since this code path is always preceded by an error_report call,
we don't lose the command line reporting.

.travis.yml: basic compile and check recipes

This adds a build matrix definition for travis-ci.org continuous
integration service. It is usable on any public repository hosted on
GitHub. Once you have created an account signed into Travis you can
enable it on selected projects via travis-ci.org/profile. Alternatively
you can configure the service hooks on GitHub via the repository
Settings tab,then Service Hooks and selecting Travis.

Once setup Travis will automatically test every push as well as any pull
requests submitted to that repository.

The build matrix is currently split by target architecture (see TARGETS
environment variable) because a full build of QEMU can take some time.
This way you get quick feedback for any obvious errors. The additional
environment variables exist to allow additional builds to tweak the
environment. These are:

EXTRA_CONFIG - extra terms passed to configure
EXTRA_PKGS - extra dev packages to install
TEST_CMD - default "make check", can be overridden

I've confined the additional stuff to x86/x86_64 for convenience.

As Travis supports clang the main builds are done twice (once for gcc
and once for clang). However clang is disabled for the debug/trace
builds for the purposes of brevity.

Other wrinkles:

 * The lttng user-space tracing back-end is disabled
   (it is currently horribly broken)
 * The ftrace back-end doesn't run "make check"
   (it requires a mounted debugfs to work)
 * There are two debug enabled build (with and without TCG interpreter)

pc: disable pci-info

The BIOS that we ship in 1.7 does not use pci info
from host and so far isn't going to use it.
Taking in account problems it caused see 9604f70fdf and
to avoid future incompatibility issues, it's safest to
disable that interface by default for all machine types
including 1.7 as it was never exposed/used by guest.
And properly remove/cleanup it during 1.8 development cycle.

block: Print its file name if backing file opening failed

If backing file doesn't exist, the error message is confusing and
misleading:

    $ qemu /tmp/a.qcow2
    qemu: could not open disk image /tmp/a.qcow2: Could not open file: No
    such file or directory

But...

    $ ls /tmp/a.qcow2
    /tmp/a.qcow2

    $ qemu-img info /tmp/a.qcow2
    image: /tmp/a.qcow2
    file format: qcow2
    virtual size: 8.0G (8589934592 bytes)
    disk size: 196K
    cluster_size: 65536
    backing file: /tmp/b.qcow2

Because...

    $ ls /tmp/b.qcow2
    ls: cannot access /tmp/b.qcow2: No such file or directory

This is not intuitive. It's better to have the missing file's name in
the error message. With this patch:

    $ qemu-io -c 'read 0 512' /tmp/a.qcow2
    qemu-io: can't open device /tmp/a.qcow2: Could not open backing
    file: Could not open '/stor/vm/arch.raw': No such file or directory
    no file open, try 'help open'

Which is a little bit better.

block/drive-mirror: Check for NULL backing_hd

It should be possible to execute the QMP "drive-mirror" command in
"none" sync mode and "absolute-paths" mode even for block devices
lacking a backing file.

"absolute-paths" does in fact not require a backing file to be present,
as can be seen from the "top" sync mode code path. "top" basically
states that the device should indeed have a backing file - however, the
current code catches the case if it doesn't and then simply treats it as
"full" sync mode, creating a target image without a backing file (in
"absolute-paths" mode). Thus, "absolute-paths" does not imply the target
file must indeed have a backing file.

Therefore, the target file may be left unbacked in case of "none" sync
mode as well, if the specified device is not backed either. Currently,
qemu will crash trying to dereference the backing file pointer since it
assumes that it will always be non-NULL in that case ("none" with
"absolute-paths").
