Update Python to 3.13.0 and add support to Windows on AMD64. Rewrite
packaging of pywin32 because it is no longer shipped via separate binary
installers, but has migrated to use pip.
# Why
On one hand Ubuntu18's free LTS cycle is ended, and on the other hand Ubuntu18 does not support nodejs greater than v18.
# What's changed.
1. update the Linux Docker image to buildpack-deps:focal
2. some compatibility changes
3. use the new recommended way to install Docker ([see here](https://docs.docker.com/engine/install/ubuntu/))
See #1173
- Remove reference to `~/.emscripten`. We no longer use the home
directory to store config information by default, either in
emscripten or in emsdk.
- Remove some references to `The Emscripten Command Prompt`. While I
suppose this is referring to the windows-only `emcmdprompt.bat`, and I
suppose it means "any shell where `activate` has been run", I think
its more clear to simply avoid using the term.
Now that all the components (binaryen, emscripten and llvm) use `main`
as the branch name is makes sense to give the SDK this name.
Keep backwards compat with the old name but issue a warning when its
used.
Its not really very useful to cache the tot release in a local text
file. Instead just fetch the revsion each time `install tot` is run.
This avoids folks accidentally installing "old" tot releases.
Also, make the output a little less chatty when looking up tot version.
* Build wasm upstream
* Fix lld build for wasm-ld. Add note about compiler-rt not working.
* Address review
* Address review
* Address review
* Address review
* If targeting fastcomp Clang, apply EMCC_WASM_BACKEND=0 so that previous leftover environment with EMCC_WASM_BACKEND=1 will not cause a conflict
* Add docs about setting up Emscripten
- Remove references to non-existent `Archived Releases` section.
- Rename `Platform-Specific Notes` to `System Requirements`
- Put `SDK Maintenance` which is kind of like an FAQ at the end.
Remove obsolete docs links.
Remove downloading of the old releases list, and bundle the file in the repo.
Also the message in update-tags was wrong: we need git to do anything there now, as update-tags gets emscripten-releases using git currently (which is ok as update-tags is run by users that installed with git; otherwise they installed without git and just update the entire emsdk normally).
A bunch of info there is out of date.
Instead, let the link to the install instructions on the main site (which was there already on line 11 higher up) speak for itself; we should have just one central location for these basic instructions.
