MiniABS 1.1: HTTPS support

- Bundle current root certificates (Let's Encrypt, GTS, Sectigo, DigiCert G2,
  Amazon, ...) missing from Android 2.x's store (Roots.java, tools/gen_roots.py)
- Ask once for unknown certificates, showing the SHA-256 fingerprint, and
  remember the answer; replaces "accept any certificate" (Trust*, Settings)
- Local streaming proxy so Android 2.x's MediaPlayer can play https:// servers,
  with seeking and a fresh token per request (StreamProxy.java)
- Tests over real TLS with good, expired, wrong-host, forged and self-signed
  certificates (test/make_pki.sh, TrustTest.java)
- README: server setup for a legacy TLS 1.0 port
