By not detecting and rejecting domain names for partial literal IP
addresses properly when parsing received HTTP cookies, libcurl can be
fooled to both send cookies to wrong sites and to allow arbitrary sites
to set cookies for others.
CVE-2014-3613
Bug: http://curl.haxx.se/docs/adv_20140910A.html
Only minor edits to make it generate nice HTML output using markdown, as
this document serves both in source release tarballs as on the web site.

Historically the default "unknown" value for progress.size_dl and
progress.size_ul has been zero, since these values are initialized
implicitly by the calloc that allocates the curl handle that these
variables are a part of. Users of curl that install progress
callbacks may expect these values to always be >= 0.
Currently it is possible for progress.size_dl and progress.size_ul
to by set to a value of -1, if Curl_pgrsSetDownloadSize() or
Curl_pgrsSetUploadSize() are passed a "size" of -1 (which a few
places currently do, and a following patch will add more). So
lets update Curl_pgrsSetDownloadSize() and Curl_pgrsSetUploadSize()
so they make sure that these variables always contain a value that
is >= 0.
Updates test579 and test599.

As the current element in the list is free()d by Curl_llist_remove(),
when the associated connection is pending, reworked the loop to avoid
accessing the next element through e->next afterward.
SecCertificateCopyPublicKey() is not available on iPhone. Use
CopyCertSubject() instead to see if the certificate returned by
SecCertificateCreateWithData() is valid.

... as the struct is free()d in the end anyway. It was first pointed out
to me that one of the ->msglist assignments were supposed to have been
->pending but was a copy and paste mistake when I realized none of the
clearing of pointers had to be there.
... instead of scanning through all handles, stash only the actual
handles that are in that state in the new ->pending list and scan that
list only. It should be mostly empty or very short. And only used for
pipelining.
This avoids a rather hefty slow-down especially notable if you add many
handles to the same multi handle. Regression introduced in commit
0f147887 (version 7.30.0).

Forwards the setting as minimum ssl version (if set) to polarssl. If
the server does not support the requested version the SSL Handshake will
fail.

SecCertificateCreateWithData() returns a non-NULL SecCertificateRef even
if the buffer holds an invalid or corrupt certificate. Call
SecCertificateCopyPublicKey() to make sure cacert is a valid
certificate.
Introducing Curl_expire_latest(). To be used when we the code flow only
wants to get called at a later time that is "no later than X" so that
something can be checked (and another timeout be added).
The low-speed logic for example could easily be made to set very many
expire timeouts if it would be called faster or sooner than what it had
set its own timer and this goes for a few other timers too that aren't
explictiy checked for timer expiration in the code.
If there's no condition the code that says if(time-passed >= TIME), then
Curl_expire_latest() is preferred to Curl_expire().
If there exists such a condition, it is on the other hand important that
Curl_expire() is used and not the other.

While waiting for a host resolve, check if the host cache may have
gotten the name already (by someone else), for when the same name is
resolved by several simultanoues requests.
The resolver thread occasionally gets stuck in getaddrinfo() when the
DNS or anything else is crappy or slow, so when a host is found in the
DNS cache, leave the thread alone and let itself cleanup the mess.
If the --cacert option is used with a CA certificate bundle that
contains multiple CA certificates, iterate through it, adding each
certificate as a trusted root CA.
When enabling CURLOPT_NOBODY, libcurl effectively switches off upload
mode and will do a download (without a body). This is now better
explained in this man page.
