For tests with fake capabilities we fill in a bunch of machine types
which the tests might use. For now there's a random collection of
machine types which are not actually used. Purge the unused ones for
non-x86 machines.

When using VIR_TEST_MAIN() or VIR_TEST_MAIN_PRELOAD() macros, the
retval of mymain() will become retval of main(). Hence, mymain()
should use EXIT_FAILURE and EXIT_SUCCESS return values for
greater portability. Another reason is that otherwise our summary
printing of failed tests doesn't work (see following commit for
more info).

Historically, we declared pointer type to our types:
typedef struct _virXXX virXXX;
typedef virXXX *virXXXPtr;
But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.
This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

For testing with synthetic capabilities we pre-fill the qemu
capabilities with some machine types. Historically there were two arrays
for KVM and TCG but that's not necessary. Make both instances of x86_64
data share the same array as the other architectures do.
This will later on simplify filling in all the other machine types which
are required for the test suite.

The NUMA cells are stored directly in the virCapsHostPtr
struct. This moves them into their own struct allowing
them to be stored independantly of the rest of the host
capabilities. The change is used as an excuse to switch
the representation to use a GPtrArray too.

All of the ones being removed are pulled in by internal.h. The only
exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
that one in place.

Nowadays the test suite changes appear quite simple, just extending
test capabilities data a bit so that we aren't trying to define
invalid arch/os/virtType/machine combos

vircapstest has code to add a full host NUMA topology, that
is, one that includes all information about nodes and CPUs
including IDs; testQemuCapsInit(), which is used to create a
mock virCapsPtr for QEMU tests, however, just fakes it by
setting nnumaCell_max to some number.
While the latter approach has served us well so far, we're
going to need all the information to be filled in soon. In
order to do that, we can just move the existing code from
vircapstest to testutils and, with some renaming and
trivial tweaking, use it as-is.
Interestingly, the NUMA topology generated by the function
is rigged up so that the NUMA nodes aren't (necessarily)
numbered starting from 0, which is a nice way to spot
mistaken assumptions in our codebase.

Some compilers may get confused and decide we are calling strcmp with
NULL argument from test_virCapsDomainDataLookupLXC. Although this does
not really happen since the call is guarded with
(data->machinetype != expect_machinetype), using STRNEQ_NULLABLE is
easier to understand, less fragile, and doing so makes sure strcmp is
never called with NULL argument.

Introduce VIR_DOMAIN_VIRT_NONE to give domaintype the default value of zero.
This is specially helpful in constructing better error messages
when we don't want to look up the default emulator by virtType.
The test data in vircapstest.c is also modified to reflect this change.
There are two macros used in the test: CAPSCOMP and CAPS_EXPECT_ERR.
Both run a test case and if a failure occurred, they set the @ret
variable to a value of -1 to indicate an error. Well, that's what they
should do. Due to a typo, they set the variable to a positive one
effectively masking any failed test.
Then, we have couple of tests failing. Fix them too.

The phyp driver stuffed it into a DomainDefPtr during its attachdevice
routine, but the value is never advertised via capabilities so it should
be safe to drop.
Have the phyp driver use OSTYPE_LINUX, which is what it advertises via
capabilities.
When building without lxc support enabled, build fails with:
CLD vircapstest
vircapstest.o: In function `test_virCapsDomainDataLookupLXC':
vircapstest.c:(.text+0x9ef): undefined reference to `testLXCCapsInit'
Fix that by hiding LXC tests under appropriate #ifdef. Same applies
for QEMU and XEN.

This is a helper function to look up all capabilities data for all
the OS bits that are relevant to <domain>. This is
- os type
- arch
- domain type
- emulator
- machine type
This will be used to replace several functions in later commits.
There are two places where you'll find info on page sizes. The first
one is under <cpu/> element, where all supported pages sizes are
listed. Then the second one is under each <cell/> element which refers
to concrete NUMA node. At this place, the size of page's pool is
reported. So the capabilities XML looks something like this:
<capabilities>
<host>
<uuid>01281cda-f352-cb11-a9db-e905fe22010c</uuid>

If user or management application wants to create a guest,
it may be useful to know the cost of internode latencies
before the guest resources are pinned. For example:
<capabilities>
<host>
...
<topology>
<cells num='2'>
<cell id='0'>
<memory unit='KiB'>4004132</memory>
<distances>
<sibling id='0' value='10'/>
<sibling id='1' value='20'/>
</distances>
<cpus num='2'>
<cpu id='0' socket_id='0' core_id='0' siblings='0'/>
<cpu id='2' socket_id='0' core_id='2' siblings='2'/>
</cpus>
</cell>
<cell id='1'>
<memory unit='KiB'>4030064</memory>
<distances>
<sibling id='0' value='20'/>
<sibling id='1' value='10'/>
</distances>
<cpus num='2'>
<cpu id='1' socket_id='0' core_id='0' siblings='1'/>
<cpu id='3' socket_id='0' core_id='2' siblings='3'/>
</cpus>
</cell>
</cells>
</topology>
...
</host>
...
</capabilities>
We can see the distance from node1 to node0 is 20 and within nodes 10.
