EOL conversions

[martindsouza]

When processing strings (usually from uploaded files) contain different types of EOL characters depending on the version of the OS from which the string/file was generated from.

This function should normalize the EOLs to a EOL set of users choosing (default to chr(13)chr(10).

Ex: regexp_replace(l_clob, '[' || chr(13) || chr(10) || ']+', chr(13) || chr(10) );

Function should take in clob or string.
