renamed generated config.h to curl_config.h in order to avoid clashes when libcurl is used with other projects which also have a config.h (missing bits)

updated openssl version to latest; removed obsolete link to openssl patch since its now in the openssl releases.

doesn't work, to better fine older gnutls installs

  (http://curl.haxx.se/bug/view.cgi?id=2813123) and an a patch that fixes the
  problem:

  Url A is accessed using auth. Url A redirects to Url B (on a different
  server0. Url B reuses a persistent connection. Url B has auth, even though
  it's on a different server.

  Note: if Url B does not reuse a persistent connection, auth is not sent.

Markus Koetter provided a patch to avoid getnameinfo() usage which broke a couple of both IPv4 and IPv6 autobuilds.

to use the "standard" ENABLE_IPV6 one. Also, if port number cannot be figured
out to connect to after a name resolve (due to it not being IPv4 or IPv6),
that particular address will now simply be skipped.

  range if given colon-separated after the host name/address part. Like
  "192.168.0.1:2000-10000"

  don't know how they got wrong in the first place, but using this output
  format makes it possible to quite easily separate the string into an array
  of multiple items.

Refactor how libraries are checked for connect() function, follow-up.

Refactor how libraries are checked for connect() function,
and check for connect() as it is done for other functions.

sclose() function-like macro definition used to close a socket,
now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
config file preprocessor definitions.

check for socket() and closesocket() as it is done for other functions

socket() and closesocket() prototypes might be in socket.h
