If the cookieinfo pointer is NULL there really is nothing to save.
Without this fix, we got a problem when a handle was using shared object
with cookies and is told to "FLUSH" it to file (which worked) and then
the share object was removed and when the easy handle was closed just
afterwards it has no cookieinfo and no cookies so it decided to save an
empty jar (overwriting the file just flushed).
Test 1905 now verifies that this works.

The draft-ietf-httpbis-rfc6265bis-02 draft, specify a set of prefixes
and how they should affect cookie initialization, which has been
adopted by the major browsers. This adds support for the two prefixes
defined, __Host- and __Secure, and updates the testcase with the
supplied examples from the draft.

Ensure to perform the checks we have to enforce a sane domain in
the cookie request. The check for non-PSL enabled builds is quite
basic but it's better than nothing.

Only allow secure origins to be able to write cookies with the
'secure' flag set. This reduces the risk of non-secure origins
to influence the state of secure origins. This implements IETF
Internet-Draft draft-ietf-httpbis-cookie-alone-01 which updates
RFC6265.

Rather than jumping backwards to where failure cleanup happens
to be performed, move the failure case to end of the function
where it is expected per existing coding convention.
Closes#2965
If the formatting fails, we error out on a fatal error and
clean up on the way out. The array was however freed within
the wrong scope and was thus never freed in case the cookies
were written to a file instead of STDOUT.
Closes#2957
According to RFC6265 section 5.4, cookies with equal path lengths
SHOULD be sorted by creation-time (earlier first). This adds a
creation-time record to the cookie struct in order to make cookie
sorting more deterministic. The creation-time is defined as the
order of the cookies in the jar, the first cookie read fro the
jar being the oldest. The creation-time is thus not serialized
into the jar. Also remove the strcmp() matching in the sorting as
there is no lexicographic ordering in RFC6265. Existing tests are
updated to match.

The latest psl is cached in the multi or share handle. It is refreshed
before use after 72 hours.
New share lock CURL_LOCK_DATA_PSL controls the psl cache sharing.
If the latest psl is not available, the builtin psl is used.

... instead of truncating them.
There's no fixed limit for acceptable cookie names in RFC 6265, but the
entire cookie is said to be less than 4096 bytes (section 6.1). This is
also what browsers seem to implement.
We now allow max 5000 bytes cookie header. Max 4095 bytes length per
cookie name and value. Name + value together may not exceed 4096 bytes.

This repairs cookies for localhost.

Added test 1258 to verify.
This was a regression brought in a76825a5ef
... 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 "-").
Previously it only held references to them, which was reckless as the
thread lock was released so the cookies could get modified by other
handles that share the same cookie jar over the share interface.

Cokie with the same domain but different tailmatching property are now
considered different and do not replace each other. If header contains
following lines then two cookies will be set: Set-Cookie: foo=bar;
domain=.foo.com; expires=Thu Mar 3 GMT 8:56:27 2033 Set-Cookie: foo=baz;
domain=foo.com; expires=Thu Mar 3 GMT 8:56:27 2033
This matches Chrome, Opera, Safari, and Firefox behavior. When sending
stored tokens to foo.com Chrome, Opera, Firefox store send them in the
stored order, while Safari pre-sort the cookies.

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.

RFC 6265 section 4.1.1 spells out that the first name/value pair in the
header is the actual cookie name and content, while the following are
the parameters.
libcurl previously had a more liberal approach which causes significant
problems when introducing new cookie parameters, like the suggested new
cookie priority draft.
The previous logic read all n/v pairs from left-to-right and the first
name used that wassn't a known parameter name would be used as the
cookie name, thus accepting "Set-Cookie: Max-Age=2; person=daniel" to be
a cookie named 'person' while an RFC 6265 compliant parser should
consider that to be a cookie named 'Max-Age' with an (unknown) parameter
'person'.
