Dream 1.0.0~alpha3

Major

• Complete rework of the internal I/O model, now supporting flow control, pipe-like programming, stream transformers, low-level WebSocket events, efficient WebSocket I/O, exception passing, trivial composition with client library (2075347 to ed1c949, 5cd57e1, others).
• Convert from immutable to mutable requests and conversion of the API to t-first style (#21).
• Factor out Dream core into opam package dream-pure, to also be used in the client (2f40d67 to e106e6e, 037645f to 8652178, dd41df9, others).
• Factor out the http/af stack and helpers directly tied to it that need to be shared with the client into opam package dream-httpaf (110575d, acc2efc).
• Remove "global" (per-server) variables (d81b198).
• Rename "local" (per-message) variables to "fields" (5a54d5c).
• Use a middleware to set secrets (2529b9a).
• Use a middleware to set site prefix (3da5e23).
• Replace ?debug by just using a different error handler (640a1b2).
• Rename ?https to ?tls (7320f87).
• Miscellaneous renamings. Most old values are still temporarily present with attached deprecation attributes to help migrate.
