In some situations, it was possible that a transfer was setup to
use an specific IP version, but due do DNS caching or connection
reuse, it ended up using a different IP version from requested.
This commit changes the effect of CURLOPT_IPRESOLVE from simply
restricting address resolution to preventing the wrong connection
type being used, when choosing a connection from the pool, and
to restricting what addresses could be used when establishing
a new connection.
It is important that all addresses versions are resolved, even if
not used in that transfer in particular, because the result is
cached, and could be useful for a different transfer with a
different CURLOPT_IPRESOLVE setting.

AmiSSL replaces many functions with macros. Curl requires pointer
to some of these functions. Thus, we have to encapsulate these macros:
SHA256_Init, SHA256_Update, SHA256_Final, X509_INFO_free.

This adds the I/O prefix to indicate that those "actions" are kind-of
related to those found in select(2) or poll(2) (reading/writing).
It also adds a note where the prototypes of those functions can be found
in the source code.

... so that we can point out the root of the OpenSSL emulation headers.
Previously this used the '$includedir' variable which is wrong since
that defaults to the dir where the current configure invoke will install
the built libcurl headers: /usr/local by default.

Check the FIRST for all other protocols.
This fixes a timeout in an ftps download. The server sends a TLS
close_notify message in the same packet as the file data. The
close_notify seems to not be handled in the schannel_recv function, so
libcurl is not aware that the server has closed the connection. Thus
libcurl ends up waiting for action on the socket until a timeout is
reached. With the secondary socket check added to the data_pending
function, the close_notify is properly handled, and the ftps transfer
terminates as expected.

The libssh2 backend has SSH session associated with the connection but
the callback context is the easy handle, so when a connection gets
attached to a transfer, the protocol handler now allows for a custom
function to get used to set things up correctly.

Some of the time, we get a HYPER_TASK_EMPTY response before the status
line, headers, and body have been read. Previously, that would cause us
to poll again, leading to a 1 second timeout.
The HYPER_TASK_EMPTY docs say:
The value of this task is null (does not imply an error).
So, if we receive a HYPER_TASK_EMPTY, continue on with processing the
response.

The Curl_resolv() had special code (when built in debug mode) for when
resolving the host name "LocalHost" (using that exact casing). It would
then get the host name from the --interface option instead.
This development-only feature was not used by anything (anymore) and we
have the --resolve feature if we want to play similar tricks properly
going forward.

Writing the cookie file has multiple error conditions, and was using an

strstore() is defined as a strdup which ensures to free the target

two more cases where it can simplify the code.
Comments in the cookie code were a bit all over the place in terms of
style and wording. This takes a stab at cleaning them up by keeping to
a single style and overall shape. Some comments are moved a little and
some removed alltogether due to being redundant. No functional changes
have been made,
This is considered not harmful as a following http2_recv shall be

This is considered helpful in the specific situation where some

following the return of HTTP status 101, other than waiting for
the client-side connection preface to arrive.
