Support lookup of IPv4 literals in ares_gethostbyname(), even when the address family is set to AF_INET6.

- Introduced a SYST-based test to properly set-up name format when dealing  with the OS/400 FTP server.
- Fixed an ftp_readresp() bug preventing detection of failing control socket  and causing FTP client to loop forever.

  properly and provided a fix. http://curl.haxx.se/bug/view.cgi?id=2843008

  read stdin in a non-blocking fashion. This also brings back -T- (minus) to
  the previous blocking behavior since it could break stuff for people at
  times.

ftp://example.com;type=i if the user specified ftp://example.com without the
slash.

  strdup() that could lead to segfault if it returned NULL. I extended his
  suggest patch to now have Curl_retry_request() return a regular return code
  and better check that.

  Fix SIGSEGV on free'd easy_conn when pipe unexpectedly breaks
  Fix data corruption issue with re-connected transfers
  Fix use after free if we're completed but easy_conn not NULL

5.4 Rearrange request header order

Things to play with when you're bored

certificate tests only run on a localhost-hosted test server since the
host name is explicitly checked.

than what's absolutely necessary:

curl will do its best to use what you pass to it as a URL. It is not trying to
validate it as a syntactically correct URL by any means but is instead
VERY liberal with what it accepts.

libcurl parses most of them identically, but not all of them.

  sending of the TSIZE option. I don't like fixing bugs just hours before
  a release, but since it was broken and the patch fixes this for him I decided
  to get it in anyway.

bugs we know about that will appear in the next release (too)

  each test, so that the test suite can now be used to actually test the
  verification of cert names etc. This made an error show up in the OpenSSL-
  specific code where it would attempt to match the CN field even if a
  subjectAltName exists that doesn't match. This is now fixed and verified
  in test 311.

  (http://curl.haxx.se/bug/view.cgi?id=2835196), fixing a few compiler
  warnings when mixing ints and bools.

config.h issue hasn't been completely solved.  This will save some effort
for someone desperate to use curl on Android.

Fix OS400 makefile for tests to use the new Makefile.inc in libtest

torture tests to fail.

fix cast for some systems which are broken due to absense of socklen_t, therefore now use curl_socklen_t.

POSIX.1-2001. Note that RFC 2553 defines a prototype where the last parameter cnt is of type size_t.
Many systems follow RFC 2553. Glibc 2.0 and 2.1 have size_t, but 2.2 has socklen_t.
