Need reviewer on addition of whitespace normalizer script

[Kelly O'Hair]

Need reviewer. Adding the whitespace normalizer script as a convenience to the jdk developers.

6625113: Add the normalize and rmkw perl script to the openjdk repository or openjdk site?
http://cr.openjdk.java.net/~ohair/openjdk8/normalizer-script/webrev/

Probably a little history is warranted here. This script was originally written to normalize the
whitespace in the jdk7 sources as they entered the Mercurial repositories in "changeset 0".
It's been modified since then very slightly. I can't recall who wrote it (please speak up if you know)
but it has been a valuable tool and I've had this CR to add it to the make/scripts directory for some time.

The SCCS keyword removed (rmkw) was less useful, and I decided that it did not deserve being added.

Why whitespace normalization? This was decided a long time ago when we had a raft of complaints from
people viewing the sources with different tools and getting different views based on the TABs and trailing
blanks or trailing newlines. So we decided to normalize on no TABs, no trailing blanks on lines, and
no more than one blank line at the end of the file. This script was used to do that normalization.
