curl_formadd: fix file upload on VMS
For the standard VMS text file formats, VMS needs to read the file to
get the actual file size.
For the standard VMS binary file formats, VMS needs a special format of
fopen() call so that it stops reading at the logical end of file instead
of at the end of the blocks allocated to the file.
I structured the patch this way as I was not sure about changing the
structures or parameters to the routines, but would prefer to only call
the stat() function once and pass the information to where the fopen()
call is made.

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.

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.

darwinssl: SSLv2 connections are aborted if unsupported by the OS

formpost: better random boundaries
When doing multi-part formposts, libcurl used a pseudo-random value that
was seeded with time(). This turns out to be bad for users who formpost
data that is provided with users who then can guess how the boundary
string will look like and then they can forge a different formpost part
and trick the receiver.
My advice to such implementors is (still even after this change) to not
rely on the boundary strings being cryptographically strong. Fix your
code and logic to not depend on them that much!
I moved the Curl_rand() function into the sslgen.c source file now to be
able to take advantage of the SSL library's random function if it
provides one. If not, try to use the RANDOM_FILE for seeding and as a
last resort keep the old logic, just modified to also add microseconds
which makes it harder to properly guess the exact seed.
The formboundary() function in formdata.c is now using 64 bit entropy
for the boundary and therefore the string of dashes was reduced by 4
letters and there are 16 hex digits following it. The total length is
thus still the same.
