Since commit 7140807917, qemu agent
channel cannot be plugged in because we won't generate its path
automatically. Let's not only fix that, but also add tests for it so
next time it's checked for.

Until now, the only hot thing in this test was the name. That's because
we set the id to '-1' before every test. With this change, we test the
hotplug on live domains as the name suggests and as it should be.

In qemuHotplugCreateObjects, the ret variable was filled by
the value returned by qemuTestCapsCacheInsert.
If any of the functions after this assignment failed, we would still
return success.
Also adjust testCompareXMLToArgvHelper, where this change is just
cosmetic, because the value was overwritten right away.
After 9c17d665fd the tap device for ethernet network type is
automatically precreated before spawning qemu. Problem is, the
qemuxml2argvtest wasn't updated and thus is failing. Because of
all the APIs that new code is calling, I had to mock a lot. Also,
since the tap FDs are labeled separately from the rest of the
devices/files I had to enable NOP security driver for the test
too.

The -sdl and -net ...name=XXX arguments were both introduced
in QEMU 0.10, so the QEMU driver can assume they are always
available.

As of QEMU 0.9.1 the -drive argument can be used to configure
all disks, so the QEMU driver can assume it is always available
and drop support for -hda/-cdrom/etc.
Many of the tests need updating because a great many were
running without CAPS_DRIVE set, so using the -hda legacy
syntax.
Fixing the tests uncovered a bug in the argv -> xml
convertor which failed to handle disk with if=floppy.

So imagine you want to crate new security manager:
if (!(mgr = virSecurityManagerNew("selinux", "QEMU", false, true, false, true)));
Hard to parse, right? What about this:
if (!(mgr = virSecurityManagerNew("selinux", "QEMU",
VIR_SECURITY_MANAGER_DEFAULT_CONFINED |
VIR_SECURITY_MANAGER_PRIVILEGED)));
Now that's better! This is what the commit does.

This needs to specified in way too many places for a simple validation
check. The ostype/arch/virttype validation checks later in
DomainDefParseXML should catch most of the cases that this was covering.
The function may return NULL if something went wrong. In some places
in the tests we are not checking the return value rather than
accessing the pointer directly resulting in SIGSEGV.

The virDomainDefParse* and virDomainDefFormat* methods both
accept the VIR_DOMAIN_XML_* flags defined in the public API,
along with a set of other VIR_DOMAIN_XML_INTERNAL_* flags
defined in domain_conf.c.
This is seriously confusing & error prone for a number of
reasons:
- VIR_DOMAIN_XML_SECURE, VIR_DOMAIN_XML_MIGRATABLE and
VIR_DOMAIN_XML_UPDATE_CPU are only relevant for the
formatting operation
- Some of the VIR_DOMAIN_XML_INTERNAL_* flags only apply
to parse or to format, but not both.
This patch cleanly separates out the flags. There are two
distint VIR_DOMAIN_DEF_PARSE_* and VIR_DOMAIN_DEF_FORMAT_*
flags that are used by the corresponding methods. The
VIR_DOMAIN_XML_* flags received via public API calls must
be converted to the VIR_DOMAIN_DEF_FORMAT_* flags where
needed.
The various calls to virDomainDefParse which hardcoded the
use of the VIR_DOMAIN_XML_INACTIVE flag change to use the
VIR_DOMAIN_DEF_PARSE_INACTIVE flag.
In all other drivers we are doing so. Moreover, we don't want to parse
runtime information in attach (even if the attach is meant as live)
because we are generating the runtime info ourselves. We can't trust
users they supply sane values anyway.

When doing live attach, we are passing the inactive definition anyway
since we are passing the result of virDomainDeviceDefCopy() which does
inactive copy by default.
Moreover, we are doing the same mistake in qemuhotplugtest.
Just a side note - it makes perfect sense to parse the runtime info
like alias in qemuDomainDetachDevice and qemuDomainUpdateDeviceFlags()
as in some cases the only difference to distinguish two devices can be
just their alias.

Problem is, since 20745748 we do both, parse <alias/> elements from
XML files and call qemuAssignDeviceAliases(). While generating runtime
info for domain at runtime is just fine in the test, we can parse just
inactive XML and remove all <alias/>-es from the XML files.

If testQemuHotplugAttach succeeds, the vm->def steals the dev pointer.
However, not the envelope, which needs to be freed. In addition,
driver.config is allocated, but never freed.
The test is currently testing just device update function. However,
chardev hotplug is implemented just for device attach and detach. This
fact means, the test needs to be rewritten (the majority of the code is
still shared). Moreover, we are now able to pass VM among multiple test
runs. So for instance, while we add a device in the first run, we can
remove it in the second run.
As my punishment for the break in 7f15ebc7 (fixed in 752596b5dd) I'm
introducing this test to make sure it won't happen again. Currently,
only test for <graphics/> is supported.
