source cleanup: remove all custom typedef structs

- Stick to a single unified way to use structs
- Make checksrc complain on 'typedef struct {'
- Allow them in tests, public headers and examples

- Let MD4_CTX, MD5_CTX, and SHA256_CTX typedefs remain as they actually
typedef different types/structs depending on build conditions.

Closes #5338

conncache: various concept cleanups

More connection cache accesses are protected by locks.

CONNCACHE_* is a beter prefix for the connection cache lock macros.

Curl_attach_connnection: now called as soon as there's a connection
struct available and before the connection is added to the connection
cache.

Curl_disconnect: now assumes that the connection is already removed from
the connection cache.

hostip: move code to resolve IP address literals to `Curl_resolv`

The code was duplicated in the various resolver backends.

Also, it was called after the call to `Curl_ipvalid`, which matters in
case of `CURLRES_IPV4` when called from `connect.c:bindlocal`. This
caused test 1048 to fail on classic MinGW.

The code ignores `conn->ip_version` as done previously in the
individual resolver backends.

Move the call to the `resolver_start` callback up to appease test 655,
which wants it to be called also for literal addresses.

cleanup: remove the 'numsocks' argument used in many places

It was used (intended) to pass in the size of the 'socks' array that is
also passed to these functions, but was rarely actually checked/used and
the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries
that should be used instead.

hostip: support wildcard hosts

This adds support for wildcard hosts in CURLOPT_RESOLVE. These are
try-last so any non-wildcard entry is resolved first. If specified,
any host not matched by another CURLOPT_RESOLVE config will use this
as fallback.

Example send a.com to 10.0.0.1 and everything else to 10.0.0.2:
curl --resolve *:443:10.0.0.2 --resolve a.com:443:10.0.0.1 \
https://a.com https://b.com

This is probably quite similar to using:
--connect-to a.com:443:10.0.0.1:443 --connect-to :443:10.0.0.2:443

resolve: add CURLOPT_DNS_SHUFFLE_ADDRESSES

This patch adds CURLOPT_DNS_SHUFFLE_ADDRESSES to explicitly request
shuffling of IP addresses returned for a hostname when there is more
than one. This is useful when the application knows that a round robin
approach is appropriate and is willing to accept the consequences of
potentially discarding some preference order returned by the system's
implementation.
