80b8a0a9fb Rename stack_right_position -> stack_total_tree_size
I want to re-use the stack data structure for storing the
re-usable nodes from the previous parse tree during an edit.
In this case, the stack won't conceptually start at position
zero, so the name 'right_position' doesn't make sense.

c1565c1aae Track AST nodes' sizes in characters as well as bytes
The `pos` and `size` functions for Nodes now return TSLength structs,
which contain lengths in both characters and bytes. This is important
for knowing the number of unicode characters in a Node.

545e575508 Revert "Remove the separator characters construct"
This reverts commit 5cd07648fd.

The separators construct is useful as an optimization. It turns out that
constructing a node for every chunk of whitespace in a document causes a
significant performance regression.

e941f8c175 Fix error in document editing
When breaking down the stack in parser.c, the previous code
would not account for ubiquitous tokens. This was a problem
for a long time, but wasn't noticed until ubiquitous tokens
started being used to represent separator characters

5cd07648fd Remove the separator characters construct
Now, grammars can handle whitespace by making it another ubiquitous
token, like comments.

For now, this has the side effect of whitespace being included in the
tree that precedes it. This was already an issue for other ubiquitous
tokens though, so it needs to be fixed anyway.

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.
