This patch fixes the "SSL3_WRITE_PENDING: bad write retry" error that
sometimes occurs when sending an email over SMTPS with OpenSSL. OpenSSL
appears to require the same pointer on a write that follows a retry
(CURLE_AGAIN) as discussed here:

Mostly because we use C strings and they end at a binary zero so we know
we can't open a file name using an embedded binary zero.

The switch to using Curl_expire_latest() in commit cacdc27f was a
mistake and was against the advice even mentioned in that commit. The
comparison in asyn-thread.c:Curl_resolver_is_resolved() makes
Curl_expire() the suitable function to use.

Added initial support for WinIDN build configurations to the VC10+
project files.

As we weren't using the correct phonetic description and doing it correctly
involves funny letters that I'm sure will cause problems for people in a text
document so I instead rephrased it and link to a WAV file with a person
actually saying 'curl'.

Previously we did not handle EOF from underlying transport socket and
wrongly just returned error code CURL_AGAIN from http2_recv, which
caused busy loop since socket has been closed.  This patch adds the
code to handle EOF situation and tells the upper layer that we got
EOF.

Removed ISC_REQ_* flags from calls to InitializeSecurityContext to fix
bug in NTLM handshake for HTTP proxy authentication.

NTLM handshake for HTTP proxy authentication failed with error
SEC_E_INVALID_TOKEN from InitializeSecurityContext for certain proxy
servers on generating the NTLM Type-3 message.

The flag ISC_REQ_CONFIDENTIALITY seems to cause the problem according
to the observations and suggestions made in a bug report for the
QT project (https://bugreports.qt-project.org/browse/QTBUG-17322).

Removing all the flags solved the problem.

I use the curl repo mainly on Windows with the typical Windows git
checkout which converts the LF line endings in the curl repo to CRLF
automatically on checkout. The automatic conversion is not done on files
in the repo with mixed line endings. I recently noticed some weird
output with projects/build-openssl.bat that I traced back to mixed line
endings, so I scanned the repo and there are files (excluding the
test data) that have mixed line endings.

I used this command below to do the scan. Unfortunately it's not as easy
as git grep, at least not on Windows. This gets the names of all the
files in the repo's HEAD, gets each of those files raw from HEAD, checks
for mixed line endings of both LF and CRLF, and prints the name if
mixed. I excluded path tests/data/test* because those can have mixed
line endings if I understand correctly.

for f in `git ls-tree --name-only --full-tree -r HEAD`;
do if [ -n "${f##tests/data/test*}" ];
    then git show "HEAD:$f" | \
     ...

It interprets them as italic indictors unless we backtick the word.

Added support for Kerberos 5 to the email protocols following the recent
additions in 7.38.0.

Removed Kerberos 4 as this has been gone for a while now.

As a sort of step forward, this script will now first try to get the
data from the HTTPS URL using curl, and only if that fails it will
switch back to the HTTP transfer using perl's native LWP functionality.
To reduce the risk of this script being tricked.

Using HTTPS to get a cert bundle introduces a chicken-and-egg problem so
we can't really ever completely disable HTTP, but chances are that most
users already have a ca cert bundle that trusts the mozilla.org site
that this script downloads from.

A future version of this script will probably switch to require a
dedicated "insecure" command line option to allow downloading over HTTP
(or unverified HTTPS).

krb4 has been dropped since a while now

Edited format to look better on the web, added a "it is about trust"
section.
