[svn-r25096] Bug: HDFFV-8433

Need to unify Windows release process (zip file) and Unix release process (bin/release-> tarfile)

Solution:
Added a new option (zip) to generate Windows zip file from the release tarball.

Tested: by hand running "bin/release ... gzip zip" to verify zip file looks right.
Allen and Dana then confirmed the zip file can be used to build and test HDF5
library without error.

+# Function name: tar2zip
+# Convert the release tarball to a Windows zipball.
+#
+# Programmer: Albert Cheng
+# Creation date: 2014-04-23

+# Modifications

+# Steps:
+# 1. untar the tarball in a temporay directory;
+#    Note: do this in a temporary directory to avoid changing
+#    the original source directory which maybe around.
+# 2. convert all its text files to DOS (LF-CR) style;
+# 3. form a zip file which is usable by Windows users.

+# Parameters:
+# $1 version
+# $2 release tarball
+# $3 output zipball file name
+#
+# Returns 0 if successful; 1 otherwise
