fc920f704c src: convert all code to use virsocket.h
There are a large number of different header files that
are related to the sockets APIs. The virsocket.h header
includes all of the relevant headers for Windows and UNIX
in one convenient place. If virsocketaddr.h is already
included, then there's no need for virsocket.h

bc7e72914a util: consolidate on one free callback for hash data
This previous commit introduced a simpler free callback for
hash data with only 1 arg, the value to free:

  commit 49288fac965f0ee23db45d83ae4ef3a9a71dafd0
  Author: Peter Krempa <pkrempa@redhat.com>
  Date:   Wed Oct 9 15:26:37 2019 +0200

    util: hash: Add possibility to use simpler data free function in virHash

It missed two functions in the hash table code which need
to call the alternate data free function, virHashRemoveEntry
and virHashRemoveSet.

After the previous patch though, there is no code that
makes functional use of the 2nd key arg in the data
free function. There is merely one log message that can
be dropped.

We can thus purge the current virHashDataFree callback
entirely, and rename virHashDataFreeSimple to replace
it.

GET_THROTTLE_STATS that's defined outside of the function,
which references a 'cleanup' label. GET_THROTTLE_STATS is
only used inside qemuMonitorJSONBlockIoThrottleInfo (in fact,
the macro is undef right after it) thus it is safe to erase
the 'cleanup' reference inside the macro, then proceed
with the usual cleanup label removal inside
qemuMonitorJSONBlockIoThrottleInfo.

3b4df5d350 Drop needless ret variable
In few places we have the following code pattern:

  int ret;
  ... /* @ret is not accessed here */
  ret = f(...);
  return ret;

This pattern can be written less verbose:

  ...
  return f(...);

This patch was generated with following coccinelle spatch:

  @@
  type T;
  constant C;
  expression f;
  identifier ret;
  @@
  -T ret = C;
   ... when != ret
  -ret = f;
  -return ret;
  +return f;

Afterwards I needed to fix a few places, e.g. comment in
virDomainNetIPParseXML() was removed too because coccinelle
thinks it refers to @ret while in fact it doesn't. Also in few
places it replaced @ret declaration with a few spaces instead of
removing the line. But nothing terribly wrong.

9a293d3315 qemu_monitor: s/size_t/ULL/ in qemuMonitorSave{Virtual,Physical}Memory
As it turns out, on my 32bit ARM machine size_t is not the same
size as ULL. However, @length argument for both functions is type
of size_t but it's treated as ULL - for instance when passed to
qemuMonitorJSONMakeCommand(). The problem is that because of
"U:size" the virJSONValueObjectAddVArgs() expects an ULL argument
but on the stack there are size_t and char * arguments (which
coincidentally add up to size of ULL). So the created command has
only two arguments "val" and incorrect "size" and no "path" which
is required.

I've tried to find other occurrences of this pattern but at the
rest of places where size_t is used it tracks size of an array so
that's safe.
