* src/qemu_conf.c (qemudParseXML): Free "obj" unconditionally.

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.

* src/util.h (to_uchar): Remove definition.
(TOLOWER): Remove definition.
(__virMacAddrCompare): Use c_tolower, not TOLOWER.
Globally:
  Where needed, change <ctype.h> to <c-ctype.h>.
  Remove unnecessary inclusion of <ctype.h>.
Ensure the global changes are never needed again:
* Makefile.maint (sc_avoid_ctype_macros): Prohibit use of ctype
macros.   Recommend c-ctype.h instead.
(sc_prohibit_c_ctype_without_use): New rule.
(sc_prohibit_ctype_h): New rule.  Disallow use of <ctype.h>.

* bootstrap: Move module list into separate variable w/less syntax.
(modules): Add c-ctype.
Update the following from gnulib:
* build-aux/useless-if-before-free:
* build-aux/vc-list-files:
* gnulib/lib/Makefile.am:
* gnulib/lib/getaddrinfo.h:

* src/xen_unified.c src/xend_internal.c src/xend_internal.h: patch
  from Cole Robinson implementing autostart for running Xen domains
Daniel

* Makefile.maint (sc_risky_ctype_macros): New rule.

* src/util.c (TOLOWER): Also convert tolower argument.

* src/storage_backend_fs.c (fileTypeInfo): Add "static" and two
"const" attributes.
(FileTypeInfo): Name the previously anonymous struct,
so the declaration of fileTypeInfo looks more conventional.
* src/xend_internal.c (sound_models): Mark as static, and
as an array of "const" entries.

These were relatively new additions to the list from here:
