...as calloc() automatically clears the area of memory with zeros.

...with the exception of the start of block statement curly brackets.

For consistency, as we seem to have a bit of a mixed bag, changed all
instances of ipv4 and ipv6 in comments and documentations to use the
correct case.

...following change in curl --version output.

Use Unix when generically writing about Unix based systems as UNIX is
the trademark and should only be used in a particular product's name.

if2ip.c:119: warning: unused parameter 'remote_scope_id'

...and some minor code style policing in the same function.

Otherwise Curl_ssl_init_certinfo() can fail and set the num_of_certs
member variable to the requested count, which could then be used
incorrectly as libcurl closes down.

The return type for this function was 0 on success and 1 on error. This
was then examined by the calling functions and, in most cases, used to
return CURLE_OUT_OF_MEMORY.

Instead use CURLcode for the return type and return the out of memory
error directly, propagating it up the call stack.

To match the curl --version output.

Merge multiple internal arrays into one, even if some variables
will not not be used. They are all created with the number of
file descriptors as their size.

Also fix possible thread handle leak in CloseHandle-loop.

Improves performance of test cases 574 and 575 by 50%.

A value of zero causes the thread to relinquish the remainder
of its time slice to any other thread of equal priority that is
ready to run. If there are no other threads of equal priority
ready to run, the function returns immediately, and the thread
continues execution.

In line with the other features listed in the --version output,
capitalise the UNIX socket feature.

The return type of this function is a boolean value, and even uses a
bool internally, so use bool in the function declaration as well as
the variables that store the return value, to avoid any confusion.

Renamed ldap_setup() to ldap_setup_connection() to follow more widely
used function naming.

Renamed rtmp_setup() to rtmp_setup_connection() to follow more widely
used function naming.

Renamed smb_setup() to smb_setup_connection() to follow more widely
used function naming.

As this pre-processor definition is defined in curl_setup.h there is no
need to include it in the Visual Studio project files.

Removed the WIN64 pre-processor definition from the libcurl project
files as:

* WIN64 is not used in our source code
* The curl projects files don't define it
* It isn't required by or used in the platform SDK
* For backwards compatability curl_setup.h defines WIN32
* The compiler automatically defines _WIN64 for x64 builds

Historically Visual Studio projects have defined WIN32, in addition to
the compiler defined _WIN32 definition, and I had incorrectly changed
that to WIN64 for the x64 libcurl builds but not in the curl projects.

As such, it is questionable whether this should be defined or not. For
more information see the following cache of a discussion that took
place on the microsoft.public.vc.mfc newsgroup:

packages/vms/backup_gnv_curl_src.com: Originally copied from Bash port.

To offer some more info and yet it doesn't use more lines.

... as it requires TLS and it was was left to warn on the default from
when default was SSL...

... as it never copies the trailing zero anyway and always just the four
bytes so let's not mislead anyone into thinking it is actually treated
as a string.

Second patch to enable Windows support using Cygwin-based OpenSSH.

Tested with CopSSH 5.0.0 free edition using an msys shell on Windows 7.

First patch to enable Windows support using Cygwin-based OpenSSH.

Removed 'next' variable in Curl_convert_form(). Rather than setting it
from 'form->next' and using that to set 'form' after the conversion
just use 'form = form->next' instead.
