* workerized RA
* Workerized (non-async) web player, using OPFS
This patch eliminates the need for asyncify and uses modern filesystem
APIs instead of the deprecated, unmaintained BrowserFS.
This is a WIP patch because it won't fully work until these two
Emscripten PRs land and are released:
https://github.com/emscripten-core/emscripten/pull/23518https://github.com/emscripten-core/emscripten/pull/23021
The former fixes an offscreen canvas context recreation bug, and the
latter adds an equivalent to BrowserFS's XHR filesystem (but without
the hazardous running-XHR-on-the-main-thread problem).
The biggest issue is that local storage of users who were using the
old version of the webplayer will be gone when they switch to the new
webplayer. I don't have a good story for converting the old BrowserFS
IDBFS contents into the new OPFS filesystem (the move is worth doing
because OPFS supports seeking and reading only bits of a file, and
because BrowserFS is dead).
I've kept around the old libretro webplayer under
pkg/emscripten/libretro-classic, and with these make flags you can
build a non-workerized RA that uses asyncify to sleep as before:
make -f Makefile.emscripten libretro=$CORE HAVE_WORKER=0 HAVE_WASMFS=0 PTHREAD=0 HAVE_AL=1
I also moved the default directory for core content on emscripten to
not be a subdirectory of the local filesystem mount, because it's
confusing to have a subdirectory that's lazily fetched and not
mirrored to the local storage. I think it won't impact existing users
of the classic web player because they already have a retroarch.cfg in
place.
* Get fetchfs working without manifest support
* makefile fixes
* Increase emscripten stack size and decrease path size to fix emscripten builds broken since de45fc2
* use modularize flags for better-behaved javascript output
* makefile and loader changes
* use specialHTMLTargets to support modular access to canvas
* bind key events to canvas, not document
This way focus means focus and we can have multiple RA instances in
one page.
* Work around an emscripten bug in strict mode
* (Emscripten) Use console.error() for error messages
* increase asyncify stack size
* Fix `-lm` flag-related compile warnings in emscripten

ever implemented for OpenGL2 driver, lots of code debt, best to
instead just keep improving the overlay system instead which is
already available for most video drivers
* Add bsv to emscripten builds
BSV has no external dependencies so this addition should be fine.

This adds '--disable-menu' which will disable all of the menu drivers
including Qt. This will also allow disabling only rgui and not the other
menu drivers.
This fixes a few subtle problems with passing CFLAGS and CXXFLAGS as
environment variables for configure.
First it will now only add these variables to config.mk when they are
actually set. If they are unset then the default optimizations in the
Makefile are set. This avoids passing more than one conflicting
optimization level to the compiler.
Next all CFLAGS are added to CXXFLAGS to avoid issues with forgetting to
set both CFLAGS and CXXFLAGS. This results in the cxx compiler getting
passed several redundant optimization levels when both the CFLAGS and
CXXFLAGS environment variabls are used. Now these uses of CFLAGS in
Makefile.common are set to DEF_FLAGS. This allows adding $(DEF_FLAGS)
to the CXXFLAGS variable without adding redundant flags from CFLAGS.
v2: Update other build files.
