Poll has long been broken on Mac OS X. Starting with 10.9 (darwin13) it
now works correctly so this patch enables it there.

When looping and closing each individual connection left open, the
SIGPIPE ignoring was not done and could thus lead to death by signal 13.

Mentioned in bug #1342

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 07b66cbf 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.

Fixed the HAVE_LONGLONG declaration as long long is supported in Visual
Studio .NET 2003 (VC7.1) onwards.

So printf(%s) on it or reading before bounds checking is wrong, fixing
it. Could previously lead to reading out of boundary.

Missed in commit dce748d3.

As of commit 6cdd88f2 the Visual Studio project file generator would
skip the first and last file from each group of files.

Carrying on from commit 11025613 added VC7.1 project files which are
capable of supporting side-by-side compilation, as well as support for
some of the third-party libraries curl uses.

This shouldn't happen with the source files in the repository, but
fixed the output when there are spurious files lying around that
contain spaces. For example "pop3 - Copy.c"

By including the offending source file in the project files the user
can then see the file and remove it if necessary.

Note: VC7.1 templates are currently not available.

Added a batch file for generating the Visual Studio project files from
the new template files.

commit 6d5f40238028f2d8c (Apr 27) or later nghttp2 is now required

Carrying on from commit 11025613 added VC7 project files which are
capable of supporting side-by-side compilation, as well as support for
some of the third-party libraries curl uses.

Carrying on from commit 11025613 added a more thorough version of
the VC6 project files which are capable of supporting side-by-side
compilation, as well as support for some of the third-party libraries
curl uses.

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!

... during the non-blocking SSL handshake

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.
