SSL: Several SSL-backend related fixes
axTLS:
This will make the axTLS backend perform the RFC2818 checks, honoring
the VERIFYHOST setting similar to the OpenSSL backend.
Generic for OpenSSL and axTLS:
Move the hostcheck and cert_hostcheck functions from the lib/ssluse.c
files to make them genericly available for both the OpenSSL, axTLS and
other SSL backends. They are now in the new lib/hostcheck.c file.
CyaSSL:
CyaSSL now also has the RFC2818 checks enabled by default. There is a
limitation that the verifyhost can not be enabled exclusively on the
Subject CN field comparison. This SSL backend will thus behave like the
NSS and the GnuTLS (meaning: RFC2818 ok, or bust). In other words:
setting verifyhost to 0 or 1 will disable the Subject Alt Names checks
too.
Schannel:
Updated the schannel information messages: Split the IP address usage
message from the verifyhost setting and changed the message about
disabling SNI (Server Name Indication, used in HTTP virtual hosting)
into a message stating that the Subject Alternative Names checks are
being disabled when verifyhost is set to 0 or 1. As a side effect of
switching off the RFC2818 related servername checks with
SCH_CRED_NO_SERVERNAME_CHECK
(http://msdn.microsoft.com/en-us/library/aa923430.aspx) the SNI feature
is being disabled. This effect is not documented in MSDN, but Wireshark
output clearly shows the effect (details on the libcurl maillist).
PolarSSL:
Fix the prototype change in PolarSSL of ssl_set_session() and the move
of the peer_cert from the ssl_context to the ssl_session. Found this
change in the PolarSSL SVN between r1316 and r1317 where the
POLARSSL_VERSION_NUMBER was at 0x01010100. But to accommodate the Ubuntu
PolarSSL version 1.1.4 the check is to discriminate between lower then
PolarSSL version 1.2.0 and 1.2.0 and higher. Note: The PolarSSL SVN
trunk jumped from version 1.1.1 to 1.2.0.
Generic:
All the SSL backends are fixed and checked to work with the
ssl.verifyhost as a boolean, which is an internal API change.

Curl_readwrite: remove debug output
The text "additional stuff not fine" text was added for debug purposes a
while ago, but it isn't really helping anyone and for some reason some
Linux distributions provide their libcurls built with debug info still
present and thus (far too many) users get to read this info.

The existing logic only cut off the fragment from the separate 'path'

Test case 5 was updated to use a fragment on a URL over a proxy.

CURLOPT_SSL_VERIFYHOST: stop supporting the 1 value
After a research team wrote a document[1] that found several live source
codes out there in the wild that misused the CURLOPT_SSL_VERIFYHOST
option thinking it was a boolean, this change now bans 1 as a value and
will make libcurl return error for it.
1 was never a sensible value to use in production but was introduced
back in the days to help debugging. It was always documented clearly
this way.
1 was never supported by all SSL backends in libcurl, so this cleanup
makes the treatment of it unified.
The report's list of mistakes for this option were all PHP code and
while there's a binding layer between libcurl and PHP, the PHP team has
decided that they have an as thin layer as possible on top of libcurl so
they will not alter or specifically filter a 'TRUE' value for this
particular option. I sympathize with that position.

FTP: prevent the multi interface from blocking
As pointed out in Bug report #3579064, curl_multi_perform() would
wrongly use a blocking mechanism internally for some commands which
could lead to for example a very long block if the LIST response never
showed.
The solution was to make sure to properly continue to use the multi
interface non-blocking state machine.

darwinssl: un-broke iOS build, fix error on server disconnect
The iOS build was broken by a reference to a function that only existed
under OS X; fixed. Also fixed a hard-to-reproduce problem where, if the
server disconnected before libcurl got the chance to hang up first and
SecureTransport was in use, then we'd raise an error instead of failing
gracefully.
The makefile is designed to build against a libmetalink devel package;
therefore is does not matter what will change inside libmetalink.
Add OpenSSL includes and defines for libmetalink-aware OpenSSL builds.

multi_runsingle: CURLOPT_LOW_SPEED_* fix for rate limitation
During the periods of rate limitation, the speedcheck function wasn't
called and thus the values weren't updated accordingly and it would then
easily trigger wrongly once data got transferred again.
Also, the progress callback's return code was not acknowledged in this
state so it could make an "abort" return code to get ignored and not
have the documented effect of aborting an ongoing transfer.

In Metalink v3, the type attribute of url element indicates the
type of the resource the URL points to. It can include URL to the
meta data, such as BitTorrent metainfo file. In Curl, we are not
interested in these meta data URLs. Instead, we are only
interested in the HTTP and FTP URLs. This change filters out
non-HTTP and FTP URLs. If we don't filter out them, it will be
downloaded by curl and hash check will fail if hash is provided
and next URL will be tried. This change will cut this useless
network transfer.
