Naming convention for gbuild methods:
- "add" is used for stuff that is logically a part of the target
  (i.e. not registered at the Module, but defined in the target's makefile)
- "use" is used for stuff that is logically a different target
  (i.e. it is registered at the Module, has it's own makefile, may be
  in a different module than the target)

This decreases debug build dir size by about 0.5G for gcc and 1G for clang.

The 'linked' files are not used by anything, and they just waste space.
If somebody wants them for debugging or whatever reason, use --backup.

remove more OUString explicit contructions

(make C++ strings look like Strings)

Remove some explicit OUString constructors in sd/.../ui

oox::dump::InputObjectBase
oox::dump::Output

Further refacorring after RTL_CONSTASCII_USTRINGPARAM removal.
Remove rtl::OUString() inside functions.

The code uses exception specifications, so it doesn't make much
sense to have them, but disable them using a gcc option. MSVC
ignores them completely, so this would leave only clang as
the only compiler to enforce them. Either the majority compiler
needs to enforce it at least in dbgutil builds (in product builds
the option can be seen as a kind of NDEBUG), or alternatively
the exception specifications should be removed.
