asyn-ares: Don't blank ares servers if none configured.

Best to just let c-ares use it's defaults if none are configured
in (lib)curl.

Reinstate "WIN32 MemoryTracking: track wcsdup() _wcsdup() and _tcsdup() usage".

This reverts commit 7ed25cc, reinstating commit 8ec2cb5.

As of 18-jul-2013 we still do have code in libcurl that makes use of these
memory functions. Commit 8ec2cb5 comment still applies and is yet valid.

These memory functions are solely used in Windows builds, so all related
code is protected with '#ifdef WIN32' preprocessor conditional compilation
directives.

Specifically, wcsdup() _wcsdup() are used when building a Windows target with
UNICODE and USE_WINDOWS_SSPI preprocessor symbols defined. This is the case
when building a Windows UNICODE target with Windows native SSL/TLS support
enabled.

Realizing that wcsdup() _wcsdup() are used is a bit tricky given that usage
of these is hidden behind _tcsdup() which is MS way of dealing with code
that must tolerate UNICODE and non-UNICODE compilation. Additionally, MS
header files and those compatible from other compilers use this preprocessor
conditional compilation directive in order to select at compilation time
whether 'wide' or 'ansi' MS API functions are used.

Without this code, Windows build targets with Windows native SSL/TLS support
enabled and MemoryTracking support enabled misbehave in tracking memory usage,
regardless of being a UNICODE enabled build or not.
CURLOPT_XFERINFOFUNCTION: introducing a new progress callback

CURLOPT_XFERINFOFUNCTION is now the preferred progress callback function
and CURLOPT_PROGRESSFUNCTION is considered deprecated.

This new callback uses pure 'curl_off_t' arguments to pass on full
resolution sizes. It otherwise retains the same characteristics: the
same call rate, the same meanings for the arguments and the return code
is used the same way.

The progressfunc.c example is updated to show how to use the new
callback for newer libcurls while supporting the older one if built with
an older libcurl or even built with a newer libcurl while running with
an older.

ftp_do_more: consider DO_MORE complete when server connects back

In the case of an active connection when ftp_do_more() detects that the
server has connected back, it must make sure to mark it as complete so
that the multi_runsingle() function will detect this and move on to the
next state.

curl_easy_perform: gradually increase the delay time

Instead of going 50,100,150 etc millisecond delay time when nothing has
been found to do or wait for, we now start lower and double each loop as
in 4,8,16,32 etc.

This lowers the minimum wait without sacrifizing the longer wait too
much with unnecessary CPU cycles burnt.

curl_multi_wait: fix revents

Commit 6d30f8ebed34e7276 didn't work properly. First, it used the wrong
array index, but this fix also:

1 - only does the copying if indeed there was any activity

2 - makes sure to properly translate between internal and external
bitfields, which are not guaranteed to match

tool_operate.c: fix passing curl_easy_setopt long arg on some x64 ABIs

We no longer pass our 'bool' data type variables nor constants as
an argument to my_setopt(), instead we use proper 1L or 0L values.

This also fixes macro used to pass string argument for CURLOPT_SSLCERT,
CURLOPT_SSLKEY and CURLOPT_EGDSOCKET using my_setopt_str() instead of
my_setopt().

This also casts enum or int argument data types to long when passed to
my_setopt_enum().

curl: fix upload of a zip file in OpenVMS

Two fixes:

1. Force output file format to be stream-lf so that partial downloads
can be continued.

This should have minor impact as if the file does not exist, it was
created with stream-lf format.  The only time this was an issue is if
there was already an existing file with a different format.

2. Fix file uploads are now fixed.

   a. VMS binary files such as ZIP archives are now uploaded
      correctly.

   b. VMS text files are read once to get the correct size
      and then converted to line-feed terminated records as
      they are read into curl.

The default VMS text formats do not contain either line-feed or
carriage-return terminated records.  Those delimiters are added by the
operating system file read calls if the application requests them.
