774ae5e3d5 In parse tables, store production ids as 16 bits 
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.

e13581b041 Fix build with GCC 11 
It seems redundant to array_init() when the structure is zeroed already
in the static assignment. But probably the fact that this code juggles
between TSTreeCursor and TreeCursor, without using a union, leaves the
compiler unable to tell that it's been initialized.

Clang 10 considers adding any offset, including 0, to the null pointer
to be undefined behavior. `(void *)NULL + 0 = kaboom`.
