This brings in the libtinfo changes. As a result this may fix breakage for some linux users, at the cost of some linux users possibly losing colors in the console (since sometimes that doesn't work with libtinfo not linked in).
This should fix some version warnings people are currently seeing - we removed the fastcomp version warnings between repos check after the last version, in emscripten-core/emscripten#8664, #259
* Structures emscripten-releases-tags.txt to mention the latest release, and then a list of all previous releases.
* Adds a new release for 1.38.33.
* If the manifest has emscripten_releases_hash, then we write out emscripten-version.txt with the proper version. We start with the hash, and check if there is a released version for it, if so we emit that, otherwise we emit the hash.
* Windows zipfile fix.
Updated to our current initial plan here:
* Add emscripten-releases-tags.txt which is a JSON file with a map of tag name to git hash in the emscripten-releases repo. Right now this file is just checked in here; in the future we may make the emsdk update it from git tags with update-tags etc.
* That file contains a "latest" tag, which is fetched for when getting latest-releases-[upstream|fastcomp]. We may want that to eventually be updated based on the latest green stuff on the bots perhaps.
* Rename the current sdk-[upstream|fastcomp]-* etc. to sdk-waterfall-[upstream\|fastcomp]-*. Then we'll have sdk-releases-[upstream|fastcomp]-* etc. This is just an internal name change - emsdk install latest-upstream still works as before, and still uses the waterfall (so we don't break our github CI).
* Add support for emsdk install latest-releases-[upstream\|fastcomp]
* Add a test using the actual emscripten-releases builds
