Various "make distcheck" and other fixes

Makefile.am:

* Use $(VAR), not @VAR@, as the former is the correct form for AC_SUBST'ed
   variables in Makefile.am files

* Touch these *.xml/*.syms files in the "dist-hook" target to prevent them
   from being regenerated, because the "make dist" process in itself
   updates the timestamps of the source files when it copies them into
   $(distdir)

* Add EXTRA_LIBS (-lrt on my system) to xsltConf.sh, as this is a required
   dependency when client applications link against -lxslt

   (note that the definition of EXTRA_LIBS has been changed; see below)

* Removed MAKEFLAGS+=--silent bits, as this is not compatible with non-GNU
   Make programs

autogen.sh:

* Add --warnings=all options to automake and autoconf invocations, to
   better catch potential problems (most of which I've fixed in this patch)

configure.in:

* Replaced obsolete macros with their current equivalents; for reference,
   see

     http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/Obsolete-Macros.html

   (I removed AC_ISC_POSIX outright because the doc states it is no longer
   useful)

* test(1) uses "=" as an operator, not "=="

* Fixed quoting on an AC_LINK_IFELSE() invocation to quell Autoconf errors

* Don't add redundant libraries to EXTRA_LIBS, because (1) this variable
   already contains LibXSLT's own additional system-library deps, and is
   useful in that form, and (2) the LibXML2 deps are already handled by
   Libtool

* Don't delete files in srcdir, and don't create the symlink to
   "Copyright" there either

   (I don't understand why this is being symlinked in the first place...)

doc/Makefile.am:

* Can't use wildcards in EXTRA_DIST, because this breaks dependencies
   (e.g. you can't "make EXSLT/\*.html"), and they only work properly when
   building inside the source tree; these have been replaced with their
   expansions. Other entries have been added here in lieu of the wildcards
   in the dist-hook target, as well as opportunistic use of the $(*PAGES)
   variables.

* Don't define an "all" target, because this steps on Automake's toes; use
   "all-local" instead

* Define and use an "xsltproc" variable to reference an in-tree-built
   version of xsltproc, instead of e.g. $(bindir)/xsltproc

   NOTE: The makefile also uses $(XSLTPROC), which names an external
   instance of the program found at configure time. Some instances of this
   could probably be changed to $(xsltproc) to remove the dependency on an
   existing installed program.

* Qualified various filenames as appropriate with $(srcdir)

* Use $(XMLLINT) consistently instead of $(bindir)/xmllint

* In the "libxslt-api.xml ..." rule, cd into $(srcdir) before invoking
   apibuild.py as this script has to run in srcdir anyway

* In the "clean-local" rule, clear out some additional files to allow
   "make distcheck" to pass

* Eliminated the redundant "maintainer-clean-local" rule

* Added a "distclean-local" rule to clear out the build directory in an
   out-of-source build to allow "make distcheck" to pass

* Added a "check-extra-dist" target to make it easier to check that
   EXTRA_DIST isn't missing anything

* Use $(MKDIR_P), not $(mkinstalldirs), as the latter name is obsolete

* Use $(VAR) instead of @VAR@

* The "dist-hook" target didn't work (if any generated files were in
   builddir and not in srcdir), and is no longer needed thanks to the
   comprehensive EXTRA_DIST variable

* Added an "uninstall-local" rule to allow "make distcheck" to pass

* Updated the .PHONY target list, removed non-existent targets

doc/symbols.xml:

* Needed to add this bit to make the generation scripts shut up

libexslt/Makefile.am:

* AM_CPPFLAGS should be used instead of INCLUDES, as the latter is an
   obsolete name

* Moved $(LIBXML_CFLAGS) to AM_CFLAGS, to segregate CFLAGS from CPPFLAGS

   (Note that $(CFLAGS) need not be added to AM_CFLAGS, because Automake
   already references both in the build rules)

* Use $(VAR) instead of @VAR@

libxslt.pc.in:

* Add EXTRA_LIBS (-lrt on my system), as this is a required dependency
   when client applications link against -lxslt

libxslt/Makefile.am:

* AM_CPPFLAGS should be used instead of INCLUDES, as the latter is an
   obsolete name

* Moved $(LIBXML_CFLAGS) to AM_CFLAGS, to segregate CFLAGS from CPPFLAGS

* Use $(VAR) instead of @VAR@, $(MKDIR_P) instead of $(mkinstalldirs)

* Use $(MKDIR_P), not $(mkinstalldirs), as the latter name is obsolete

libxslt/xsltutils.c:

* Some systems don't know about CLOCK_MONOTONIC; older Solaris knows about
   CLOCK_HIGHRES. Some systems, alas, have no usable alternative to
   CLOCK_REALTIME.

python/Makefile.am:

* AM_CPPFLAGS should be used instead of INCLUDES, as the latter is an
   obsolete name

* Moved $(LIBXML_CFLAGS) to AM_CFLAGS, to segregate CFLAGS from CPPFLAGS

* Because libxslt-py.c is (presumably) supposed to be generated every time
   at build time, don't bundle it in the dist tarball

* Use $(VAR) instead of @VAR@

* libxsltclass.py is a generated file, so it doesn't get qualified with
   $(srcdir)

* Use $(MKDIR_P) instead of (mkinstalldirs)

* Added an uninstall-local rule so that "make distcheck" passes

* Removed the $(srcdir) qualifications in the GENERATED file list, as
   these files may exist in builddir

* In the gen_prog rule, qualify the script invocation with $(srcdir), and
   set the SRCDIR environment variable so that the script can find the
   files it needs when builddir != srcdir

* Don't define an "all" target, as this steps on Automake's toes

python/generator.py:

* Get the source directory from the SRCDIR environment variable, and use
   it appropriately

python/tests/Makefile.am:

* Set CLEANFILES instead of defining a "clean" rule

* Use $(VAR) instead of @VAR@, $(MKDIR_P) instead of $(mkinstalldirs)

tests/*/Makefile.am, tests/exslt/*/Makefile.am:

* Need to clean up .memdump files for "make distcheck" to pass

* Don't define an "all" target, as this steps on Automake's toes

tests/REC/Makefile.am:

* Added two missing *.stand.out files to EXTRA_DIST

tests/XSLTMark/Makefile.am:

* Replaced the GNU-Make-specific %.out bit with a more broadly compatible
   rule

   (the "dummy" bit shuts up Automake)

* Use "$(xsltproc)" instead of "$(top_builddir)/xsltproc/xsltproc"

* Use a less $(MAKE)-heavy invocation in the "tests" target

* Replaced a conflicting "clean" target with CLEANFILES

* Added a dependency on $(xsltproc) to all the test targets

* Added a .PHONY target list

tests/docbook/Makefile.am:

* Ditched the "echo -n" bit, because it wasn't working as advertised

* Create output directories for out-of-source builds

* "$(basename $$i)" is a typo in a makefile

* Don't embed $(srcdir) in $out/$html/$fo/$msg/$xhtml, so that we can
   refer to these files in builddir or srcdir

* Add a trailing "echo" to complete the "echo -n"

* Don't output files unconditionally to srcdir (it may be read-only, for
   starters)

tests/plugins/Makefile.am:

* AM_CPPFLAGS should be used instead of INCLUDES, as the latter is an
   obsolete name

   (Note that the "$(LIBXML_CFLAGS) $(LIBXSLT_CFLAGS)" bit that was here
   can be dropped entirely, because these already appear in
   xmlsoft_org_xslt_testplugin_la_CFLAGS)

* Use noinst_LTLIBRARIES inside the WITH_MODULES conditional instead of
   EXTRA_LTLIBRARIES, as this is cleaner (and disallows building the plugin
   if module support is disabled)

* Need to clean up *.res files for "make distcheck" to pass

* Use the abs_builddir variable conveniently provided to us by Automake
   instead of a GNU Make $(shell ...) construct

xslt-config.in:

* Add EXTRA_LIBS (-lrt on my system), as this is a required dependency
   when client applications link against -lxslt

xsltproc/Makefile.am:

* AM_CPPFLAGS should be used instead of INCLUDES, as the latter is an
   obsolete name

* Moved $(LIBXML_CFLAGS) into AM_CFLAGS

* Use $(VAR) instead of @VAR@

* Need to clean .memdump for "make distcheck" to pass

* Added rules to build lib[e]xslt.la if needed, which allows test
   makefiles to build xsltproc on the fly even if nothing else has been
   built already

* Create .memdump file in the "tests" target, as it's being grepped
   afterward
Hardening of code checking node types in EXSLT
Fix system-property with unknown namespace

The empty string should be returned, see bug #631803.
Forwards-compatible processing of unknown top level elements

check for gmtime - on mingw* hosts will enable date-time function
xsltproc should return an error code if xinclude fails

When running xsltproc with the --xinclude option and if the included file
contains parse errors, then xsltproc exits with a success return code (0)
rather than an error code.  This is despite the fact that parser error
messages are printed out.
* xsltproc/xsltproc.c: check xinclude processing function return code,

FreeBSD portability fixes

Around behaviour and compile flags for localtime and EXSLT date support
Portability fix for testThreads.c

Similar to the one in libxml2, don't assume threads id are scalars
document('') fails to return stylesheets parsed from memory

If an XSL stylesheet is from memory (e.g. xmlParseMemory), then xpath
expressions referencing "document('')" will never return a match.

When getting down into it, I understand the logic "document() is resolved
relative to the XSL's location, reading from memory has no location, therefore
buzz off", but the XSL spec seems to address this:

http://www.w3.org/TR/xslt#document
"Note that a zero-length URI reference is a reference to the document relative
to which the URI reference is being resolved; thus document("") refers to the
root node of the stylesheet; the tree representation of the stylesheet is
exactly the same as if the XML document containing the stylesheet was the
initial source document."

The fact that the behavior differs in this case between fromFile & fromMemory
definitely caught me off guard, and IMHO fixing that scenario is worth the
one-off-ness of the fix.
xincludestyle wasn't protected with LIBXML_XINCLUDE_ENABLED
