OpenSSL passes out and outlen variable uninitialized to
select_next_proto_cb callback function. If the callback function
returns SSL_TLSEXT_ERR_OK, the caller assumes the callback filled
values in out and outlen and processes as such. Previously, if there
is no overlap in protocol lists, curl code does not fill any values in
these variables and returns SSL_TLSEXT_ERR_OK, which means we are
triggering undefined behavior. valgrind warns this.
This patch fixes this issue by fallback to HTTP/1.1 if there is no
overlap.
Make all code use connclose() and connkeep() when changing the "close
state" for a connection. These two macros take a string argument with an
explanation, and debug builds of curl will include that in the debug
output. Helps tracking connection re-use/close issues.
Commit 517b06d657 (in 7.36.0) that brought the CREDSPERREQUEST flag
only set it for HTTPS, making HTTP less good at doing connection re-use
than it should be. Now set it for HTTP as well.
Simple test case
"curl -v -u foo:bar localhost --next -u bar:foo localhos"

The variable wasn't assigned at all until step3 which would lead to a
failed connect never assigning the variable and thus returning a bad
value.

In commit 0b3750b5c2 (released in 7.36.0) we fixed a timeout issue
but instead broke the timings.
To fix this, I introduce a new timestamp to use for the timeouts and
restored the previous timestamp and timestamp position so that the old
timer functionality is restored.
In addition to that, that change also broke connection timeouts for when
more than one connect was used (as it would then count the total time
from the first connect and not for the most recent one). Now
Curl_timeleft() has been modified so that it checks against different
start times depending on which timeout it checks.
Test 1303 is updated accordingly.

Whilst the qop directive isn't required to be present in a client's
response, as servers should assume a qop of "auth" if it isn't
specified, some may return authentication failure if it is missing.
To cater for the automatic generation of the new Visual Studio project
files, moved the lib file list into a separated variable so that lib
and lib/vtls can be referenced independently.
-p takes a list of Mozilla trust purposes and levels for certificates to
include in output. Takes the form of a comma separated list of
purposes, a colon, and a comma separated list of levels.
Now nghttp2_submit_request returns assigned stream ID, we don't have
to check stream ID using before_stream_send_callback. The
adjust_priority_callback was removed.
Depending on compiler line 3505 could generate the following warning or
error:
* warning: ISO C90 forbids mixed declarations and code
* A declaration cannot appear after an executable statement in a block
* error C2275: 'size_t' : illegal use of this type as an expression
As there's a default connection timeout and this wrongly used the
connection timeout during a transfer after the connection is completed,
this function would trigger timeouts during transfers erroneously.

If the precision is indeed shorter than the string, don't strlen() to
find the end because that's not how the precision operator works.
I also added a unit test for curl_msnprintf to make sure this works and
that the fix doesn't a few other basic use cases. I found a POSIX
compliance problem that I marked TODO in the unit test, and I figure we
need to add more tests in the future.

Commit 07b66cbfa4 unfortunately broke native NTLM message support in
compilers, such as VC6, VC7 and others, that don't support long long
type declarations. This commit fixes VC6 and VC7 as they support the
__int64 extension, however, we should consider an additional fix for
other compilers that don't support this.
set.infilesize in this case was modified in several places, which could
lead to repeated requests using the same handle to get unintendent/wrong
consequences based on what the previous request did!
This makes the findprotocol() function work as intended so that libcurl
can properly be restricted to not support HTTP while still supporting
HTTPS - since the HTTPS handler previously set both the HTTP and HTTPS
bits in the protocol field.
This fixes --proto and --proto-redir for most SSL protocols.
This is done by adding a few new convenience defines that groups HTTP
and HTTPS, FTP and FTPS etc that should then be used when the code wants
to check for both protocols at once. PROTO_FAMILY_[protocol] style.

As this makes curl_global_init_mem() behave the same way as
curl_global_init() already does in that aspect - the same number of
curl_global_cleanup() calls is then required to again decrease the
counter and then eventually do the cleanup.
