Re-classify redirect=
option as a modifier option
This commit moves the parsing, compiling and enforcement of the `redirect=` and `redirect-rule=` network filter options into the static network filtering engine as modifier options -- just like `csp=` and `queryprune=`. This solves the two following issues: - https://github.com/gorhill/uBlock/issues/3590 - https://github.com/uBlockOrigin/uBlock-issues/issues/1008#issuecomment-716164214 Additionally, `redirect=` option is not longer afflicted by static network filtering syntax quirks, `redirect=` filters can be used with any other static filtering modifier options, can be excepted using `@@` and can be badfilter-ed. Since more than one `redirect=` directives could be found to apply to a single network request, the concept of redirect priority is introduced. By default, `redirect=` directives have an implicit priority of 0. Filter authors can declare an explicit priority by appending `:[integer]` to the token of the `redirect=` option, for example: ||example.com/*.js$1p,script,redirect=noopjs:100 The priority dictates which redirect token out of many will be ultimately used. Cases of multiple `redirect=` directives applying to a single blocked network request are expected to be rather unlikely. Explicit redirect priority should be used if and only if there is a case of redirect ambiguity to solve.
