Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Updates #6865

Maisem Ali 2c89b3a601 control/controlbase: make Conn.Write return consumed bytes
Currently `Write` returns the number of ciphertext bytes written.
According to the docs for io.Writer, Write should return the amount
of bytes consumed from the input.
```
// Write writes len(p) bytes from p to the underlying data stream.
// It returns the number of bytes written from p (0 <= n <= len(p))
// and any error encountered that caused the write to stop early.
// Write must return a non-nil error if it returns n < len(p).
// Write must not modify the slice data, even temporarily.
Write(p []byte) (n int, err error)
```

Fixes #4126

David Anderson d5a7eabcd0 control/controlbase: enable asynchronous client handshaking.
With this change, the client can obtain the initial handshake message
separately from the rest of the handshake, for embedding into another
protocol. This enables things like RTT reduction by stuffing the
handshake initiation message into an HTTP header.

Similarly, the server API optionally accepts a pre-read Noise initiation
message, in addition to reading the message directly off a net.Conn.
