uTLS for meek-client camouflage
Use utls (paper) for TLS camouflage instead of a headless Firefox helper. The camouflage will not be as robust as a headless browser, but the complexity will be lower. It will be portable to platforms that don't have a convenient Firefox instance to use. It will fix #12774 (moved), which is caused by tor starting multiple instances of meek-client-torbrowser, which in turn start multiple instances of Firefox, which error because they are using the same profile directory.
