handling code.  In particular, if you had a section of XML like:

    <disk type='file' device='cdrom'>
      <target dev='hdc' bus='ide'/>
      <readonly/>
    </disk>

This used to work with older libvirt, but now fails.  This is because we are
actually passing the literal string (null) to the qemu command-line, which qemu
barfs on.  This patch fixes it up by making it blank, which allows qemu to
continue on it's merry way.

* src/qemu_conf.c (qemudNetworkIfaceConnect):
Suggestion from Daniel P. Berrange.

introduced into the qemudNetworkIfaceConnect() function.  In particular, there
is a call:

    if (VIR_ALLOC_N(vm->tapfds, vm->ntapfds+2) < 0)
        goto no_memory;

However, the tapfds structure is used to track *all* of the tap fds, and is
called once for each network that is being attached to the domain.  VIR_ALLOC_N
maps to calloc().  So the first network would work just fine, but if you had
more than one network, subsequent calls to this function would blow away the
stored fd's that were already there and fill them all in with zeros.  This
causes multiple problems, from the qemu domains not starting properly to
improper cleanup on shutdown.  The attached patch just changes the VIR_ALLOC_N()
to a VIR_REALLOC_N(), and everything is happy again.

Up to now, we've been avoiding ctype functions like isspace, isdigit,
etc.  because they are locale-dependent.  Now that we have the c-ctype
functions, we can start using *them*, to make the code more readable
with changes like these:

-        /* This may not work on EBCDIC. */
-        if ((*p >= 'a' && *p <= 'z') ||
-            (*p >= 'A' && *p <= 'Z') ||
-            (*p >= '0' && *p <= '9'))
+        if (c_isalnum(*p))

-    while ((*cur >= '0') && (*cur <= '9')) {
+    while (c_isdigit(*cur)) {

Also, some macros in conf.c used names that conflicted with
standard meaning of "BLANK" and "SPACE", so I've adjusted them
to be in line with the definition of e.g., isblank.
In addition, I've wrapped those statement macros with do {...} while (0),
so that we can't forget the ";" after a use.  There was one like that
already (fixed below).  The missing semicolon would mess up automatic
indenting.
