Debugging routines to print out XML, SP Object, and Display Item trees.

Fix crash resulting from r11646.

some memleak fixes (Bug #1043571)

revert rev 11646: build issue with dbus (forgot to adapt some more, dbus was not enabled) and other issues

converted some c-string usage to c++ string class usage: should fix some memory leaks

Switch to top-level glib headers. Thanks to DimStar for patch

Add possibility to check validity of attributes and usefulness of properties. This code adds the ability to check for every elment in an SVG document if its attributes are valid and the styling properties are useful. Options under the SVG Output section of the Inkscape Preferences dialog control what should be checked when, and what actions should be taken if invalid attributes or non-useful properties are found.

Doxygen cleanup.

Super duper mega (fun!) commit: replaced encoding=utf-8 with fileencoding=utf-8 in all 1074 Vim modelines. The reason for this is that (a) setting the encoding isn't nice, and (b) Vim 7.3 (with modeline enabled) disallows it and pops up an error whenever you open any file with it ("invalid modeline"). Also corrected five deviant modestrings: * src/ui/widget/dock.cpp and src/ui/widget/dock.h: missing colon at the end * src/ui/dialog/tile.cpp: removed gratuitous second colon at the end * src/helper/units-test.h: removed gratuitous space before a colon * share/extensions/export_gimp_palette.py: missing textwidth=99 That's my geekiest commit yet.

Making it so that including simple-node.h will generate an error

* Lots of documentation for the Inkscape::XML namespace * Doxygen fixes for a few files * Garbage-collected allocator for STL containers

remove "public private" virtual methods from XML::Node

remove additional unnecessary indirection in tree operations

access some SimpleNode fields directly

remove last traces of "floating nodes"

re-enable assertions

Back out the `document != NULL' assertions added to SimpleNode constructors in r18847 (see https://bugs.launchpad.net/inkscape/+bug/239101).

force single single document over a node's lifetime

plumb document references a little deeper in

Applying fixes for gcc 4.3 build issues (closes LP: #169115)

warning cleanup

make subtree monitoring part of XML::Node's interface

plumb XML::Document parameter into duplication, courtesy of bryce

merge XML::Session into XML::Document

switch everyone to simpler debug event API

shared_ptr -> ptr_shared

optimization: do not notify any listeners if attributes' new value is the same as old

share_static -> share_static_string

replace Util::SharedCStringPtr with the more general Util::shared_ptr<>
