b91f48ced2 Call handle_error even when error occurs exactly where expected 
Previously, if an error happened right at the beginning of an error
production, the error node would be immediately shifted onto the stack
without calling the error handling function.

77941c85ff Avoid building incomplete error nodes during lexing 
The lexer doesn't know the expected symbols, so it doesn't have enough
information to construct error nodes. Now, when it encounters an invalid
character, it returns NULL and the parser builds a correct error node.

that spans the given position.

1e79ed794b Allow multiple top-level nodes 
Now, the root node of a document is always a document node.
It will often have only one child node which corresponds to the grammar's
start symbol, but not always. Currently, it may have more than one child
if there are ubiquitous tokens such as comments at the beginning of the
document. In the future, it will also be possible be possible to have multiple
for the document to have multiple children if the document is partially parsed.

8da9219c3a Remove redundant functions for Documents 
There's no need for a `string` function since one already
exists for Nodes.

Now the root node is always stored on the document. This
means callers of `ts_document_root_node` don't need to release
its return value.

eecbcccee0 Remove generated parsers' dependency on the runtime library 
Generated parsers no longer export a parser constructor function.
They now export an opaque Language object which can be set on
Documents directly. This way, the logic for constructing parsers
lives entirely in the runtime. The Languages are just structs which
have no load-time dependency on the runtime
