* remove 'const' from GetForbiddenCharacters
* CharInfoMap -> Map
* pInf -> pForbiddenCharacters
* remove 'inline' from the function defined within the class definition
* some code simplifications

seeing as Z_PREFIX is what we set in our internal zlib
and one of these was ZLIB_PREFIXB anyway

While I try to wrap head around subtleties for linked undo in
Impress outline view, disable that here for the while. Better than
a crash for sure.

Added:
* rtl::OString::matchL
* rtl::OString::endsWith
* rtl::OString::endsWithL
* rtl::OString::indexOfL
* rtl::OString::replaceFirst
* rtl::OString::replaceAll
* rtl::OString::getToken
* rtl::OUString::endsWith
* rtl::OUString::replaceFirst
* rtl::OUString::replaceFirstAsciiL
* rtl::OUString::replaceFirstAsciiLAsciiL
* rtl::OUString::replaceAll
* rtl::OUString::replaceAllAsciiL
* rtl::OUString::replaceAllAsciiLAsciiL
* rtl::OUString::getToken
plus underlying C functions where necessary

Deprecated:
* comphelper::string::remove
* comphelper::string::getToken

Removed:
* comphelper::string::searchAndReplaceAsciiL
* comphelper::string::searchAndReplaceAllAsciiWithAscii
* comphelper::string::searchAndReplaceAsciiI
* comphelper::string::replace
* comphelper::string::matchL
* comphelper::string::matchIgnoreAsciiCaseL
* comphelper::string::indexOfL

Also fixed some apparent misuses of RTL_CONSTASCII_USTRINGPARAM ->
RTL_CONSTASCII_STRINGPARAM.

At least some of the things corrected, also (c) myself.
