This reverts commit 7ed25ccf, reinstating commit 8ec2cb55.

As of 18-jul-2013 we still do have code in libcurl that makes use of these
memory functions. Commit 8ec2cb55 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 ...

See XC_AMEND_DISTCLEAN comments for details.

Pass back the revents that happened for the user-provided file
descriptors.

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

Fixed issue with static build for MSVC2010.

After some investigation I've discovered known issue
http://public.kitware.com/Bug/view.php?id=11240 When .rc file is linked
to static lib it fails with following linker error

LINK : warning LNK4068: /MACHINE not specified; defaulting to X86
file.obj : fatal error LNK1112: module machine type 'x64' conflicts with
target machine type 'X86'

Fix add target property /MACHINE: for MSVC generation.

Also removed old workarounds - it caused errors during msvc build.

Use from qssl backend

Merge for resync

Use simple seeding method upon RANDOM_FILE seeding method failure.

Implement wrappers around strtod to convert the user argument to a
double with sane error checking. Use this to allow --max-time and
--connect-timeout to accept decimal values instead of strictly integers.

The manpage is updated to make mention of this feature and,
additionally, forewarn that the actual timeout of the operation can
vary in its precision (particularly as the value increases in its
decimal precision).

strto* functions happily chomp off leading whitespace, so simply
checking for str[0] can lead to false negatives. Do the full parse and
check the out value instead.

Update the build_vms.com to detect and use zlib shared image installed
by the ZLIB kit produced by Jean-Francois Pieronne, and the also the
future ZLIB 1.2.8 kit in addition to the older ZLIB kits.

Also fix the indentation to match one of the common standards used for
VMS DCL command files and removed the hard tab characters.

Tested on OpenVMS 8.4 Alpha and IA64, and OpenVMS 7.3 VAX.

Newer versions of curl are referencing a sk_pop symbol while the HP
OpenSSL library has the symbol in uppercase only.

This reverts commit 3a0e931f because
the documentation of --time-cond was duplicated by mistake.
