From the last commit, decorate all the symbols with the version
macros. Also add the version macros in the docs.

* configure.in:
* pango/Makefile.am:
New generated public header file pango-features.h. Currently contains
the version information. In the future, can be expanded to define
which backends have been enabled, etc.
* pango/pango.def:
* pango/pango-utils.h:
* pango/pango-utils.c:
New public macros and functions: PANGO_VERSION_ENCODE(),
PANGO_VERSION_MAJOR, PANGO_VERSION_MINOR, PANGO_VERSION_MICRO,
PANGO_VERSION, PANGO_VERSION_STRING, PANGO_VERSION_CHECK(),
pango_version(), pango_version_string(), pango_version_check().
* docs/pango-docs.sgml:
* docs/pango-sections.txt:
* docs/tmpl/pango-version.sgml:
Docs for new symbols, in a new section.
* examples/renderdemo.c (show_version):
If run-time Pango lib version is different than the compile-time one,
show that one too.
* pango/pango.h:
#include <pango-utils.h> as well as almost all other public pango-*.h
headers (though, the other ones were already included indirectly).
The only public pango-*.h header pango.h shouldn't include are
pango-ot.h (which is really misnamed) and pango-modules.h (that should
not be needed by 99.99% users anyway).
* docs/Makefile.am:
* docs/check.docs: Test to check that all symbols are documented and
properly hooked into documentation tree.
* pango/pango.rc.in:
* pango/pangoft2.rc.in:
* pango/pangowin32.rc.in:
Update, reflecting some internal symbol changes.
* pango/check.defs: Improve.

* pango/pango-glyph.h: move pango_shape and pango_reorder_items in
here.
* pango/pango-break.h: move most of pango.h in here, so that

* pango/makeenums.pl: script to generate pango-enum-types.[hc]
* pango/Makefile.am (pango_headers): built pango-enum-types.h,
pango-enum-types.c that do enum type registration; add

* pango/break.c: include individual headers, not pango.h

Eliminate PangoCFont; For X, encode charset into upper
16 bits of 32 bit glyph IDs. Revise X core <=> module
interfaces to support this change.
Remove support for X_XLFD_FONT_RANGES, which has been
disavowed by its proponents, in favor of checking metrics
to figure out if the relevant characters are there.
Rework operation of basic module to be faster and simple.
* modules/Makefile.am: temporarily comment out Tamil and
Hangul modules until I finish mucking with the
X font interfaces.
