32c887e4b7 virnumamock: Allow CPU-less NUMA nodes
The original virNumaGetNodeCPUs() returns an empty virBitmap if
given NUMA node has no CPUs. But that's not how our mock behaves
- it looks under $fakesysfs/node/node$N/cpulist only to find an
empty file which is then passed to virBitmapParseUnlimited()
which threats such input as error.

Fortunately, we don't have any fake sysfs data where this path is
hit, but we might soon.

c8238579fb lib: Drop internal virXXXPtr typedefs
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:

31daccf5a5 virNumaGetHugePageInfo: Return page_avail and page_free as ULL
https://bugzilla.redhat.com/show_bug.cgi?id=1569678

On some large systems (with ~400GB of RAM) it is possible for
unsigned int to overflow in which case we report invalid number
of 4K pages pool size. Switch to unsigned long long.

We hit overflow in virNumaGetPages when doing:

    huge_page_sum += 1024 * page_size * page_avail;

because although 'huge_page_sum' is an unsigned long long, the
page_size and page_avail are both unsigned int, so the promotion
to unsigned long long doesn't happen until the sum has been
calculated, by which time we've already overflowed.

Turning page_avail into a unsigned long long is not strictly
needed until we need ability to represent more than 2^32
4k pages, which equates to 16 TB of RAM. That's not
outside the realm of possibility, so makes sense that we
change it to unsigned long long to avoid future problems.

7008e10869 util: Remove virsysfs and instead enhance virFileReadValue* functions
It is no longer needed thanks to the great virfilewrapper.c.  And this
way we don't have to add a new set of functions for each prefixed
path.

While on that, add two functions that weren't there before, string and
scaled integer reading ones.  Also increase the length of the string
being read by one to accompany for the optional newline at the
end (i.e. change INT_STRLEN_BOUND to INT_BUFSIZE_BOUND).

9368095bb8 tests: Add virnumamock
All mocked functions are related to numactl/virNuma and rely only on
virsysfs, so the paths they touch can be nicely controlled.  And
because it is so nicely self-contained NUMA mock, it is named
numamock (instead of naming it after the test that will use it first).

We need top level API mock because some APIs might call libnuma
directly, e.g. virNumaIsAvailable(), virNumaGetMaxNode().
