The default is now a whopping 64K matches, which "should be enough for
everyone". You can use the new `ts_query_cursor_set_match_limit`
function to set this to a lower limit, such as the previous default of
32.
This function (and the similar `ts_tree_cursor_goto_first_child_for_byte`)
allows you to efficiently seek the tree cursor to a given position,
exploiting the tree's internal balancing, without having to visit
all of the preceding siblings of each node.
This restores the original signatures of the `set_byte_range` and
`set_point_range` functions. Now, the QueryCursor will properly report
matches that intersect, but are not fully contained by its range.

This is a follow-up to my previous commit 1badd131f9 .
I've made this an extra patch as it requires a minor
API change in <tree_sitter/parser.h>.
This commit moves the remaining generated tables into
the read-only segment.
Before:

This PR adds an API to get name of the field of TSNode's child.
It uses same set of arguments as that of ts_node_child, but returns
field name if it is found, otherwise it returns NULL.
This API is useful to implement custom printing of S-expressions such
as following:
"(binary_expression
(binary_expression_left (identifier))
(binary_expression_operator ("+"))
(binary_expression_right (identifier)
)"
Currently, ts_node_string does not allow any customization for printing.
Also remove the use of bitfields from the parse table format.
In all cases, bitfields were not necessary to achieve the
current binary sizes. Avoiding them makes the binaries more
portable.
There was no way to make this change backward-compatible,
so we have finally dropped support for parsers generated
with an earlier version of Tree-sitter.
At some point, when Atom adopts this version of Tree-sitter,
this change will affect Atom users who have installed packages
using third-party Tree-sitter parsers. The packages will need
to be updated to use a regenerated version of the parsers.
