[Libreoffice] Include Guards (easy 6)

This is in response to Easy Task 6, removal of various include guards  
throughout the source code.

I have created and included a small python script to identify and  
remove these include guards.  Here is the basics on how to use it:

python fixguard.py somefile.cxx

Or recursively:

# Go to the clone/writer directory.
find . -name '*.cxx' -exec grep python $HOME/fixguard.py {} \;
git diff
# verify that the diffs are sane and check them in.

import sys
import re

exp = '#ifndef.*_HXX.*\n(#include.*\n)#endif.*'

filename = sys.argv[1] # warning no error checking

data = open(filename).read()

o = open("/tmp/fixed","w")
o.write( re.sub(exp,"\\1",data) )
o.close()
os.rename("/tmp/fixed", filename)
