Yeah, back the O[UString contents with direct new/delete calls in a real
implementation body instead of current thin header-only wrapper around
the C-API which backs onto rtl_allocateMemory/rtl_freeMemory.

Alternative, replace rtl_allocateMemory/rtl_freeMemory in strtmpl.cxx
with new/delete, and remove the inline bad_alloc throwing from the
header and assume that there isn't any existing users of the c-api that
ever checked that rtl_uString2String failed
