* refactor: format header files with uncrustify
* fixup(justin): skip formatting of terminfo_defs.h
* fixup: force winsock2 to be included first
* fixup: simplify disable/enable directive to "uncrustify:off/on"
Note: formatc.lua was unable to swallow some newer additions to ExprASTNodeType
(specifically `kExprNodeOr = '|'` and probably something else), so all `= …`
were dropped: in any case they only were there in order to not bother updating
viml_pexpr_debug_print_ast_node and since it is now known all nodes which will
be present it is not much of an issue.
