QuickJS, the Next Generation: a mighty JavaScript engine

- simplify column number tracking using a pointer to the beginning of line instead of `eol` + `mark`. - add `js_parse_error_pos` to report syntax errors with exact source position for token parsing errors. This makes the syntax error reports much more precise. eg: exact position of UTF-8 encoding error, invalid escape sequence, etc. - add `JSSourcePos` type to use single opaque object for token source position - add `emit_pos` to set the precise source position in code generation - change `emit_op` to no longer emit source positions from `s->last_line_num` and `s->last_col_num`. - remove `last_line_num` and `last_col_num` `JSParserState` members - runtime errors on calls report the column number of calling function or method name. - runtime errors on `new` expressions report the column number of the `neẁ` keyword. - do not show source position in backtrace if debug information is missing - fix spurious parsing bugs when `js_parse_skip_parens_token` could not reparse the current token because of stack overflow detection. - `js_parse_save_pos` now saves the current token and `js_parse_seek_back` always restores the token, hence never fails, while `js_parse_seek_token` reparses the saved token. This is needed to handle the weird semantics of `"\1"; "use strict";` - simplify html comment detection - update **tests/test_builtin,js** with more informative messages - improve `assert()` and **tests/test_language.js** tests - update **v8.txt** for updated column numbers in remaining errors |

⚡️ QuickJS - A mighty JavaScript engine
Friendly QuickJS fork focused on reigniting the project.
Overview
In October 2023 @bnoordhuis and @saghul decided to fork the QuickJS project with the aim of reigniting it. They reached out to the original authors (@bellard and @chqrlie) about their intentions.
As of December 2023 the initial goal was somewhat accomplished. @bellard resumed working on the project and both parties have been pulling patches from each other since.
As of early 2024 both projects agree the proper path forward involves merging both projects and combining the efforts. While that may take a while, since both projects diverged in certain areas, there is willingness to go in this direction from both sides.
