If a % ended the statement, the string's trailing NUL would be skipped
and memory past the end of the buffer would be accessed and potentially
displayed as part of the --write-out output. Added tests 1440 and 1441
to check for this kind of condition.

proxy CONNECT response headers from the user callback functions
CURLOPT_HEADERFUNCTION and CURLOPT_WRITEFUNCTION.

CURLOPT_SUPPRESS_CONNECT_HEADERS and allow suppressing proxy CONNECT

Closes https://github.com/curl/curl/pull/783
A client MUST ignore any Content-Length or Transfer-Encoding header
fields received in a successful response to CONNECT.
"Successful" described as: 2xx (Successful). RFC 7231 4.3.6
Prior to this change such a case would cause an error.
In some ways this bug appears to be a regression since c50b878. Prior to
that libcurl may have appeared to function correctly in such cases by
acting on those headers instead of causing an error. But that behavior
was also incorrect.

Test 1903 is doing HTTP pipelining, and that is a timing and ordering
sensitive operation and this fails far too often on the Travis CI
leading to people more or less ignoring test failures there. Not good.
The end of pipelning is probably coming sooner rather than later
anyway...
... because it causes confusion with users. Example URLs:
"http://[127.0.0.1]:11211:80" which a lot of languages' URL parsers will
parse and claim uses port number 80, while libcurl would use port number
11211.
"http://user@example.com:80@localhost" which by the WHATWG URL spec will
be treated to contain user name 'user@example.com' but according to
RFC3986 is user name 'user' for the host 'example.com' and then port 80
is followed by "@localhost"
Both these formats are now rejected, and verified so in test 1260.

This is likely to be the case when building from a tar ball release
package which includes a prebuilt man page. In that case, test the
packaged man page instead. This only makes a difference when building
out-of-tree (in-tree, the location in both cases is identical).
The character set in POSIX is set by the locale defined by (in
decreasing order of precedence) the LC_ALL, LC_CTYPE and LANG
environment variables (CHARSET was used by libidn but not libidn2).
LC_ALL is cleared to ensure that LC_CTYPE takes effect, but LC_ALL is
not used to set the locale to ensure that other parts of the locale
aren't overridden. Since there doesn't seem to be a cross-platform way
of specifying a UTF-8 locale, and not all systems may support UTF-8, a
<precheck> is used to skip the test if UTF-8 can't be verified to be
available. Test 1035 was also converted to UTF-8 for consistency, as
the actual character set used there is irrelevant to the test.
This patch uses a different UTF-8 locale than the last attempt, namely
en_US.UTF-8. This one has been verified on 7 different Linux and BSD
distributions and is more complete and usable than the locale UTF-8 (on
at least some systems).
This reverts commit ecd1d020ab.
That commit caused test failures on my Debian Linux machine for all
changed test cases. We need to reconsider how that should get done.
Character set in POSIX is set by the locale defined (in decreasing order
of precedence) by the LC_ALL, LC_CTYPE and LANG environment variables (I
believe CHARSET is only historic). LC_ALL is cleared to ensure that
LC_CTYPE takes effect, but LC_ALL is not used to set the locale to
ensure that other parts of the locale aren't overriden, if set. Since
there doesn't seem to be a cross-platform way of specifying a UTF-8
locale, and not all systems may support UTF-8, a <precheck> is used
(where relevant) to skip the test if UTF-8 isn't in use. Test 1035 was
also converted to UTF-8 for consistency, as the actual character set
used there is irrelevant to the test.

Under condition using http_proxy env var, noproxy list was the
combination of --noproxy option and NO_PROXY env var previously. Since
this commit, --noproxy option overrides NO_PROXY environment variable
even if use http_proxy env var.
Closes#1140
The combination of --noproxy option and http_proxy env var works well
both for proxied hosts and non-proxied hosts.
However, when combining NO_PROXY env var with --proxy option,
non-proxied hosts are not reachable while proxied host is OK.
This patch allows us to access non-proxied hosts even if using NO_PROXY
env var with --proxy option.

We're mostly saying just "curl" in lower case these days so here's a big
cleanup to adapt to this reality. A few instances are left as the
project could still formally be considered called cURL.
- Call Curl_initinfo on init and duphandle.
Prior to this change the statistical and informational variables were
simply zeroed by calloc on easy init and duphandle. While zero is the
correct default value for almost all info variables, there is one where
it isn't (filetime initializes to -1).

... to make it less likely that we forget that the function actually
does case insentive compares. Also replaced several invokes of the
function with a plain strcmp when case sensitivity is not an issue (like
comparing with "-").
Cokie with the same domain but different tailmatching property are now
considered different and do not replace each other. If header contains

stored tokens to foo.com Chrome, Opera, Firefox store send them in the
stored order, while Safari pre-sort the cookies.
