* lib/yaml.rb: reworking YAML::Stream to use the new
emitter.
* lib/yaml/stream.rb: ditto.
* lib/yaml/rubytypes.rb: added Object#yaml_new.
* lib/yaml/tag.rb: the tag_subclasses? method now
shows up in the class. allow taguri to be set using an accessor.
continue support of Object#to_yaml_type.
* ext/syck/rubyext.c: new emitter code. yaml_new and yaml_initialize
get called, should they be present. consolidated all the diaspora of internal
node types into the family below YAML::Syck::Node -- Map,
Seq, Scalar -- all of whom are SyckNode structs pointing to
Ruby data. moved Object#yaml_new into the node_import and made it the
default behavior. the target_class is always called wih yaml_new, prepended
a parameter, which is the klass. loaded nodes through GenericResolver show their style.
new Resolver#tagurize converts type ids to taguris.
* ext/syck/implicit.re: were 'y' and 'n' seriously omitted??
* ext/syck/emitter.c: renovated emitter, walks the tree in advance.
consolidated redundant block_styles struct into
the scalar_style struct. (this means loaded nodes can now
be sent back to emitter and preserve at least its very basic
formatting.)
* ext/syck/gram.c: headless documents of any kind allowed.
* ext/syck/node.c: new syck_replace_str methods and syck_empty_*
methods for rewriting node contents, while keeping the ID
and other setup info. added syck_seq_assign.
* ext/syck/syck.h: reflect block_styles and new node functions.
