Merge branch 'flatten-rules-into-productions'

This branch had diverged considerably, so merging it required changing a lot
of code.

Rename node accessor methods
...
Instead of child() vs concrete_child(), next_sibling() vs next_concrete_sibling(), etc,
the default is switched: child() refers to the concrete syntax tree, and named_child()
refers to the AST. Because the AST is abstract through exclusion of some nodes, the
names are clearer if the qualifier goes on the AST operations

No more ambiguity nodes.
Also, when merging parse stacks, merge their successors if needed.

Treat parse conflicts as errors in grammar compilation
...
For now, only reduce/reduce conflicts w/ no tie-breaking precedence
are treated as errors. The rest are dropped, because shift/reduce
conflicts are currently very common because we don't have a way
of specifying associativity along w/ precedence.

Rename examples directory to spec/fixtures
...
- I want to move away from having complete grammars for real languages
(e.g. javascript, golang) in this repo. These languages take a long
time to compile, and they now exist in their own repos
(node-tree-sitter-javascript etc).
- I want to start testing more compiler edge cases through integration
tests, so I want to put more small, weird grammars in here. That makes
me not want to call the directory `examples`.
