vtls: use a backend standard message for "ALPN: offers %s"
I call it VTLS_INFOF_ALPN_OFFER_1STR, the '1str' meaning that the
infof() call also needs a string argument: the ALPN ID.

vtls: provide a unified APLN-disagree string for all backends
Also rephrase to make it sound less dangerous:

 "ALPN: server did not agree on a protocol. Uses default."

f36e32b5b8 bearssl: fix EXC_BAD_ACCESS on incomplete CA cert
- Do not create trust anchor object for a CA certificate until after it
  is processed.

Prior to this change the object was created at state BR_PEM_BEGIN_OBJ
(certificate processing begin state). An incomplete certificate (for
example missing a newline at the end) never reaches BR_PEM_END_OBJ
(certificate processing end state) and therefore the trust anchor data
was not set in those objects, which caused EXC_BAD_ACCESS.

8af1cef29e bearssl: fix connect error on expired cert and no verify
- When peer verification is disabled use the x509_decode engine instead
  of the x509_minimal engine to parse and extract the public key from
  the first cert of the chain.

Prior to this change in such a case no key was extracted and that caused
CURLE_SSL_CONNECT_ERROR. The x509_minimal engine will stop parsing if
any validity check fails but the x509_decode won't.

vtls: pass on the right SNI name

60738f398c vtls: Fix a memory leak if an SSL session cannot be added to the cache
On connection shutdown, a new TLS session ticket may arrive after the
SSL session cache has already been destructed. In this case, the new
SSL session cannot be added to the SSL session cache.

The callers of Curl_ssl_addsessionid() need to know whether the SSL
session has been added to the cache. If it has not been added, the
reference counter of the SSL session must not be incremented, or memory
used by the SSL session must be freed. This is now possible with the new
output parameter "added" of Curl_ssl_addsessionid().

infof: remove newline from format strings, always append it
- the data needs to be "line-based" anyway since it's also passed to the
  debug callback/application

- it makes infof() work like failf() and consistency is good

- there's an assert that triggers on newlines in the format string

- Also removes a few instances of "..."

- Removes the code that would append "..." to the end of the data *iff*
  it was truncated in infof()

tls: add USE_HTTP2 define
This abstracts across the two HTTP/2 backends: nghttp2 and Hyper.

Add our own define for the "h2" ALPN protocol, so TLS backends can use
it without depending on a specific HTTP backend.

lib: pass in 'struct Curl_easy *' to most functions
... in most cases instead of 'struct connectdata *' but in some cases in
addition to.

- We mostly operate on transfers and not connections.

- We need the transfer handle to log, store data and more. Everything in
  libcurl is driven by a transfer (the CURL * in the public API).

- This work clarifies and separates the transfers from the connections
  better.

- We should avoid "conn->data". Since individual connections can be used
  by many transfers when multiplexing, making sure that conn->data
  points to the current and correct transfer at all times is difficult
  and has been notoriously error-prone over the years. The goal is to
  ultimately remove the conn->data pointer for this reason.

9024b01387 bearssl: Improve I/O handling
Factor out common I/O loop as bearssl_run_until, which reads/writes TLS
records until the desired engine state is reached. This is now used for
the handshake, read, write, and close.

Match OpenSSL SSL_write behavior, and don't return the number of bytes
written until the corresponding records have been completely flushed
across the socket. This involves keeping track of the length of data
buffered into the TLS engine, and assumes that when CURLE_AGAIN is
returned, the write function will be called again with the same data
and length arguments. This is the same requirement of SSL_write.

Handle TLS close notify as EOF when reading by returning 0.
