g_regex_unref reports an error if called with a NULL argument.
We have two cases in the code where we (possibly) call it on a NULL
argument. The interesting one is in virDomainQemuMonitorEventCleanup.
Based on VIR_CONNECT_DOMAIN_QEMU_MONITOR_EVENT_REGISTER_REGEX, we unref
data->regex, which has two problems:
* On the client side, flags is -1 so the comparison is true even if no
regex was used, reproducible by:
$ virsh qemu-monitor-event --timeout 1
which results in an ugly error:
(process:1289846): GLib-CRITICAL **: 14:58:42.631: g_regex_unref: assertion 'regex != NULL' failed
* On the server side, we only create the regex if both the flag and the
string are present, so it's possible to trigger this message by:
$ virsh qemu-monitor-event --regex --timeout 1
Use a non-NULL comparison instead of the flag to decide whether we need
to unref the regex. And add a non-NULL check to the unref in the
VirtualBox test too.

Both accept a NULL value gracefully and virStringFreeList
does not zero the pointer afterwards, so a straight replace
is safe.

Getting rid of unistd.h from our headers will require more work than
just fixing the broken mingw build. Revert it until I have a more
complete proposal.

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.

Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

We have couple of functions that operate over NULL terminated
lits of strings. However, our naming sucks:
virStringJoin
virStringFreeList
virStringFreeListCount
virStringArrayHasString
virStringGetFirstWithPrefix
We can do better:
virStringListJoin
virStringListFree
virStringListFreeCount
virStringListHasString
virStringListGetFirstWithPrefix

In the test, the snapshot XML is written into a file that's located
under:
abs_srcdir/vboxsnapshotxmldata/testResult.vbox
However, the abs_srcdir doesn't have to be necessarily writable. It
should have been abs_builddir instead. Moreover, the label in the func
creating the file is called 'fail' while it fulfils the duty of
'cleanup' label.

This structure contains the data to be saved in the VirtualBox XML file
and can be manipulated with severals exposed functions.
The structure is created by vboxSnapshotLoadVboxFile taking the
machine XML file.
It also can rewrite the XML by using vboxSnapshotSaveVboxFile.
