2020-09-11	ast: implement inline ut_is_type() helper	Jo-Philipp Wich
	The ut_is_type() function simplifies checking the extended tag type of a given JSON object value. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-10	treewide: implement default lstrip_blocks and trim_blocks behaviour	Jo-Philipp Wich
	Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-10	treewide: eliminate unused function arguments	Jo-Philipp Wich
	Also introduce convenience macro for registering function arrays in modules. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-08	parser, eval: use an ut_op flag to denote postfix access	Jo-Philipp Wich
	The current code still abused the JSON value pointer to denote postfix access for certain operations which led to a crash when freeing the parser state due to an attempt to put a (void *)1 pointer. Since we do have the ability to set flags on operations since the AST rework, use this much cleaner approach and avoid the invalid pointer hackery. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-07	ast, eval, lexer: keep track of overflows when parsing numbers	Jo-Philipp Wich
	This allows number literals that exceed the range INT64_MIN..INT64_MAX to be truncated to the respective min and max values in a defined manner. It also makes it possible to have the expression `{{ -9223372036854775808 }}` actually result in `-9223372036854775808`. Since negation and number declaration are separate operations, the value would be first truncated to `9223372036854775807` and then negated, making it impossible to write a literal INT64_MIN value without tracking the overflow. Also fix the number parsing logic to not trucate intergers to 32bit. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-06	treewide: refactor internal AST structures	Jo-Philipp Wich
	- unify operand and value tag structures - use a contiguous array for storing opcodes - use relative offsets for next and children ops - defer function creation to runtime - rework "this" context handling by storing context pointer in scope tags Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-02	treewide: rename double and null value constructor functions	Jo-Philipp Wich
	Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-02	ast, eval: add tagged object handling	Jo-Philipp Wich
	In order to implement prototype chains later on, introduce a tagged object value type and use it when processing object declarations. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-09-02	ast: add functionality to deal with extended data types	Jo-Philipp Wich
	Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2020-08-25	treewide: introduce this keyword	Jo-Philipp Wich
	Support a new keyword `this` which allows functions to access the context they're called upon. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
