/*
** Convenience wrapper which calls builtin_request_js() for a series
** of builtin scripts named fossil.NAME.js. The first time it is
** called, it also calls builtin_emit_script_fossil_bootstrap() to
** initialize the window.fossil JS API. The first argument is the NAME
** part of the first API to emit. All subsequent arguments must be
** strings of the NAME part of additional fossil.NAME.js files,
** followed by a NULL argument to terminate the list.
**
** e.g. pass it ("fetch", "dom", "tabs", 0) to load those 3 APIs (or
** pass it ("fetch","tabs",0), as "dom" is a dependency of "tabs", so
** it will be automatically loaded). Do not forget the trailing 0!
**
** If it is JS_BUNDLED then this routine queues up an emit of ALL of
** the JS fossil.XYZ.js APIs which are not strictly specific to a
** single page, and then calls builtin_fulfill_js_requests(). The idea
** is that we can get better bundle caching and reduced HTTP requests
** by including all JS, rather than creating separate bundles on a
** per-page basis. In this case, all arguments are ignored!
**
** This function has an internal mapping of the dependencies for each
** of the known fossil.XYZ.js modules and ensures that the
** dependencies also get queued (recursively) and that each module is
** queued only once.
**
** If passed a name which is not a base fossil module name then it 
** will fail fatally!
**
** DO NOT use this for loading fossil.page.*.js: use
** builtin_request_js() for those.
**
** If the current JS delivery mode is *not* JS_BUNDLED then this
** function queues up a request for each given module and its known
** dependencies, but does not immediately fulfill the request, thus it
** can be called multiple times.
**
** If a given module is ever passed to this more than once, either in
** a single invocation or multiples, it is only queued for emit a
** single time (i.e. the 2nd and subsequent ones become
** no-ops). Likewise, if a module is requested but was already
** automatically queued to fulfill a dependency, the explicit request
** becomes a no-op.
**
** Bundled mode is the only mode in which this API greatly improves
** aggregate over-the-wire and HTTP request costs. For other modes,
** reducing the inclusion of fossil.XYZ APIs to their bare minimum
** provides the lowest aggregate costs. For debate and details, see
** the discussion at:
**
** https://fossil-scm.org/forum/forumpost/3fa2633f3e
**
** In practice it is normally necessary (or preferred) to call
** builtin_fulfill_js_requests() after calling this, before proceeding
** to call builtin_request_js() for page-specific JS, in order to
** improve cachability.
**



















































































** Minor caveat: the purpose of emitting all of the fossil.XYZ JS APIs
** at once is to reduce over-the-wire transfers by enabling cross-page
** caching, but if there are other JS scripts pending via
** builtin_request_js() when this is called then they will be included
** in the JS request emitted by this routine, resulting in a different
** script URL than if they were not included. Thus, if a given page
** has its own scripts to install via builtin_request_js(), they
** should, if possible, be delayed until after this is called OR the
** page should call builtin_fulfill_js_requests() to flush the request
** queue before calling this routine.
**
** Achtung: the fossil.page.XYZ.js files are page-specific, containing
** the app-level logic for that specific page, and loading more than
** one of them in a single page will break that page. Each of those
** expects to "own" the page it is loaded in, and it should be loaded
** as late in the JS-loading process as feasible, ideally bundled (via
** builtin_request_js()) with any other app-/page-specific JS it may
** need.
**
** Example usage:
**

** builtin_fossil_js_bundle_or("dom", "fetch", 0);

**
** In bundled mode, that will (the first time it is called) emit all
** builtin fossil JS APIs and "fulfill" the queue immediately. In
** non-bundled mode it will queue up the "dom" and "fetch" APIs to be
** emitted the next time builtin_fulfill_js_requests() is called.
