Register HTTP and HTTPS proxy dialers and implement CONNECT-based
tunneling for HTTP proxies.
The new dialer supports:
- Plain HTTP proxies using CONNECT
- HTTPS proxies by performing a TLS handshake before CONNECT
- Optional basic authentication via Proxy-Authorization (with a warning
when creds are used over cleartext HTTP)
This allows all_proxy to be set to http:// or https:// URLs, enabling
data transfer through HTTP(S) proxies.
### Purpose
Allow peers to connect using HTTP Proxies (CONNECT)
### Testing
Tested with both HTTP and HTTPS proxy connection, using both no auth and
plain authentication.
### Screenshots
No visual change
### Documentation
