doh: disable DOH for the cases it doesn't work
Due to limitations in Curl_resolver_wait_resolv(), it doesn't work for
DOH resolves. This fix disables DOH for those.

Limitation added to KNOWN_BUGS.

Fixes #3850
Closes #3857

Claes Jakobsson d8cae791f4 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.

  (ie before a host is resolved) with a pointer to backend-specific
  resolver data. Currently this is only useful for ares.

- Add new option CURLOPT_RESOLVER_START_DATA to set a user pointer to

Daniel Stenberg 4f45240bc8 lib: include curl_printf.h as one of the last headers
curl_printf.h defines printf to curl_mprintf, etc. This can cause
problems with external headers which may use
__attribute__((format(printf, ...))) markers etc.

To avoid that they cause problems with system includes, we include
curl_printf.h after any system headers. That makes the three last
headers to always be, and we keep them in this order:

 curl_printf.h
 curl_memory.h
 memdebug.h

None of them include system headers, they all do funny #defines.

Tobias Stoeckmann 851c29269b hostip: Fix signal race in Curl_resolv_timeout.
A signal handler for SIGALRM is installed in Curl_resolv_timeout. It is
configured to interrupt system calls and uses siglongjmp to return into
the function if alarm() goes off.

The signal handler is installed before curl_jmpenv is initialized.
This means that an already installed alarm timer could trigger the
newly installed signal handler, leading to undefined behavior when it
accesses the uninitialized curl_jmpenv.

Even if there is no previously installed alarm available, the code in
Curl_resolv_timeout itself installs an alarm before the environment is
fully set up. If the process is sent into suspend right after that, the
signal handler could be called too early as in previous scenario.

To fix this, the signal handler should only be installed and the alarm
timer only be set after sigsetjmp has been called.

Michael Wallner 09b5a99816 resolve: cache lookup for async resolvers
While waiting for a host resolve, check if the host cache may have
gotten the name already (by someone else), for when the same name is
resolved by several simultanoues requests.

The resolver thread occasionally gets stuck in getaddrinfo() when the
DNS or anything else is crappy or slow, so when a host is found in the
DNS cache, leave the thread alone and let itself cleanup the mess.
