Currently the logging APIs have a 'const char *category' parameter
which indicates where the log message comes from. This is typically
a combination of the __FILE__ string and other prefix. Split the
__FILE__ off into a dedicated parameter so it can passed to the
log outputs

When launching a QEMU guest the binary is probed to discover
the list of supported CPU names. Remove this probing with a
simple lookup of CPU models in the qemuCapsPtr object. This
avoids another invocation of the QEMU binary during the
startup path.
As a nice benefit we can now remove all the nasty hacks from
the test suite which were done to avoid having to exec QEMU
on the test system. The building of the -cpu command line
can just rely on data we pre-populate in qemuCapsPtr.

Nothing uses the return value, and creating it requries otherwise
unnecessary strlen () calls.
This cleanup is conceptually independent from the rest of the series
(although the later patches won't apply without it). This just seems
a good opportunity to clean this up, instead of entrenching the unnecessary
return value in the virLogOutputFunc instance that will be added in this
series.

The "dump-guest-core' option is new option for the machine type
(-machine pc,dump-guest-core) that controls whether the guest memory
will be marked as dumpable.
While testing this, I've found out that the value for the '-M' options
is not parsed correctly when additional parameters are used. However,
when '-machine' is used for the same options, it gets parsed as
expected. That's why this patch also modifies the parsing and creating
of the command line, so both '-M' and '-machine' are recognized. In
QEMU's help there is only mention of the 'machine parameter now with
no sign of the older '-M'.
This patch cleans up building the "-boot" parameter and while on that
fixes one inconsistency by modifying these things:
- I completed the unfinished virDomainBootMenu enum by specifying
LAST, declaring it and also declaring the TypeFromString and
TypeToString parameters.
- Previously mentioned TypeFromString and TypeToString are used when
parsing the XML.
- Last, but not least, visible change is that the "-boot" parameter
is built and parsed properly:
- The "order=" prefix is used only when additional parameters are
used (menu, etc.).
- It's rewritten in a way that other parameters can be added
easily in the future (used in following patch).
- The "order=" parameter is properly parsed regardless to where it
is placed in the string (e.g. "menu=on,order=nc").
- The "menu=" parameter (and others in the future) are created
when they should be (i.e. even when bootindex is supported and
used, but not when bootloader is selected).
Based exclusively on work by Eric Blake in a patch posted with the same
subject. However some modifications related to comments and my plans to

Added WITH_INTERFACE as the only automake variable deciding whether to

Commit ee3d3893 missed the fact that (unsigned char)<<(int)

longer than four bytes.
Also, I failed to run 'make syntax-check' on my commit 4bba6579;
for whatever odd reason, ffs lives in a different header than ffsl.

In many places we store bitmap info in a chunk of data
(pointed to by a char *), and have redundant codes to
set/unset bits. This patch extends virBitmap, and convert
those codes to use virBitmap in subsequent patches.
This patch adds full support for EOI setting for domains. Because this
is CPU feature (flag), the model needs to be added even when it's not
specified. Fortunately this problem was already solved with kvmclock,
so this patch simply abuses that.
And due to the size of the patch (17 lines) I dared to include the tests.

The current qemu capabilities are stored in a virBitmapPtr
object, whose type is exposed to callers. We want to store
more data besides just the flags, so we need to move to a
struct type. This object will also need to be reference
counted, since we'll be maintaining a cache of data per
binary. This change introduces a 'qemuCapsPtr' virObject
class. Most of the change is just renaming types and
variables in all the callers

Technically speaking we should wait until we receive the QMP
greeting message before attempting to send any QMP monitor
commands. Mostly we've got away with this, but there is a race
in some QEMU which cause it to SEGV if you sent it data too
soon after startup. Waiting for the QMP greeting avoids the
race

To be able to test the QEMU monitor code, we need to have a fake
QEMU monitor server. This introduces a simple (dumb) framework
that can do this. The test case registers a series of items to
be sent back as replies to commands that will be executed. A
thread runs the event loop looking for incoming replies and
sending back this pre-registered data. This allows testing all
QEMU monitor code that deals with parsing responses and errors
from QEMU, without needing QEMU around

After discussion with DB we decided to rename the new iolimit

This is also backed by the fact that the term I/O Limits has
vanished from newer storage admin documentation.

This test case validates the correct generation of SELinux labels
