Fix parallel build and bootstrap on MS-Windows.

 nt/makefile.w32-in: (all): Don't depend on stamp_BLD and on maybe-bootstrap.
 (all-other-dirs-$(MAKETYPE)): Depend on maybe-bootstrap.
 (bootstrap-gmake): Invoke the "clean" and build targets in 2
 separate commands, so they run in that order even under "make -j".
 lib/makefile.w32-in (gnulib, all): Don't depend on stamp_BLD.
 lib-src/makefile.w32-in (ALL): Now the list of executables, not of phony
 targets.
 (.PHONY): Only make-docfile is its prerequisite now.
 (make-docfile): Don't depend on stamp_BLD.  Add a comment about
 the need in this target.
 (ctags, etags, ebrowse, hexl, movemail, emacsclient)
 (test-distrib): Phony targets removed.
 ($(BLD)/test-distrib.exe): Run test-distrib as part of the recipe.
 (all): Don't depend on stamp_BLD.

Build test-distrib on MS-Windows and run it during the build.

Support building on MS-Windows with libxml2.

 src/makefile.w32-in (OBJ2): Add xml.$(O).
 (GLOBAL_SOURCES): Add xml.c.
 ($(BLD)/xml.$(O)): New dependency list.
 src/xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
 [!WINDOWSNT]: New macros.
 (init_libxml2_functions, libxml2_loaded_p): New functions.
 (parse_region): Call fn_xmlCheckVersion instead of using the macro
 LIBXML_TEST_VERSION.  Call libxml2 functions via the fn_* macros.
 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
 Calls xmlCleanupParser only if libxml2 was loaded (or statically
 linked in).
 (Flibxml_parse_html_region, Flibxml_parse_xml_region): Call
 init_libxml2_functions before calling libxml2 functions.
 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
 src/emacs.c: Don't include libxml/parser.h.
 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
 xmlCleanupParser directly.
 src/ lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.

 nt/configure.bat: Support building with libxml2.
 nt/INSTALL:
 nt/README.W32: Add information about libxml2.

 lisp/term/w32-win.el (dynamic-library-alist): Add libxml2 DLLs.

 lib-src/makefile.w32-in (obj): Add xml.o.

Fix typo that broke non-Windows builds.

* xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
Avoid unnecessary pointer scanning in garbage collection (Bug#10780).

* alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
(mark_memory): Mark Lisp_Objects only if pointers might hide in
objects, as mark_maybe_pointer will catch them otherwise.

ChangeLog fix
Check pkg-config exit status when configuring (Bug#10626).

* configure.in (PKG_CHECK_MODULES): Do not assume that pkg-config
works; check its exit status.  Problem reported by Jordi Gutiérrez
Hermoso in
<http://lists.gnu.org/archive/html/emacs-devel/2012-01/msg00787.html>.
src/xml.c (init_libxml2_functions) [WINDOWSNT]: Remove unused local variable.
src/makefile.w32-in ($(BLD)/xml.$(O)): Reorder entry.
* lisp/loadup.el: Load bindings before cus-start.
This reduces somewhat the number of "rogue" settings in emacs -Q.

Fix invocation of Hunspell by ispell.el.

 lisp/textmodes/ispell.el (ispell-check-version): For hunspell, set
 ispell-encoding8-command to "-i", without a trailing space.
 (ispell-start-process): For hunspell, use '("-i" ENCODING), in 2
 separate command-line arguments, to specify the encoding, since
 that's how hunspell expects it.
* lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
proper alignment.
