[PATCH] add SAL_WARN_UNUSED_RESULT in OString and OUString where app...

Hi,

I have submitted a patch for review:

    https://gerrit.libreoffice.org/1186

To pull it, you can do:

    git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/86/1186/1

add SAL_WARN_UNUSED_RESULT in OString and OUString where appropriate

String used to do some operation by modifying itself
whereas OUString never does that and when a modificaiton is needed
it create a new copy.

so it is very easy when one convert String code to OUString code to
miss stuff like

sString.ToUpperCase()

which need to be converted into

sString = sString.toAsciiUpperCase()

and not
sString.toAsciiUpperCase()

This patch make the compiler generate a warning in that later _wrong_ case
