1944e3ddc0
Previosly (since commit 9ac98e6e34)
it was expected to gradually remove SAL_U/W usage in Windows code
by replacing with reinterpret_cast or changing to some bettertypes.
But as it's useful to make use of fact that LibreOffice and Windows
use compatible representation of strings, this commit puts these
functions to a better-suited o3tl, and recommends that the functions
be consistently used throughout Windows-specific code to reflect the
compatibility and keep the casts safe.
