this modifies codemaker so that, for an UNO enum, we generate code
that effectively looks like:
#ifdef LIBO_INTERNAL_ONLY && HAVE_CX11_CONSTEXPR
enum class XXX {
ONE = 1
};
constexpr auto ONE = XXX_ONE;
#else
...the old normal way..
#endif
which means that for LO internal code, the enums are scoped.
The "constexpr auto" trick acts like an alias so we don't have to
use scoped naming everywhere.

"Dynamic Exception Specifications" for details.
Most changes have been done automatically by the rewriting loplugin:dynexcspec
(after enabling the rewriting mode, to be committed shortly). The way it only
removes exception specs from declarations if it also sees a definition, it
identified some dead declarations-w/o-definitions (that have been removed
manually) and some cases where a definition appeared in multiple include files
(which have also been cleaned up manually). There's also been cases of macro
paramters (that were used to abstract over exception specs) that have become
unused now (and been removed).
Furthermore, some code needed to be cleaned up manually
(avmedia/source/quicktime/ and connectivity/source/drivers/kab/), as I had no
configurations available that would actually build that code. Missing @throws
documentation has not been applied in such manual clean-up.

"Dynamic Exception Specifications" for details.
This leaves some #include <...Exception.hpp> in the generated code that are no
longer needed by the generated files themselves. But C++ implementation classes
still use dynamic exception specifications and usually don't repeat the relevant
#includes, so postpone removal until the implementation classes are cleaned up
in a later step.

Any::get(Any const &) const
operator >>=(Any const &, Any &)
operator <<=(Any &, Any const &)
that don't make much sense (the first is always true, the rest can be replaced
with operator =, which additionally supports move semantics). For 3rd-party
compatibility, do this only for LIBO_INTERNAL_ONLY, however.
However, some generic template code did benefit from operator >>= working also
for Any, so make up for that with a new (LIBO_INTERNAL_ONLY, given that
operator >>= still covers if fine for !LIBO_INTERNAL_ONLY) fromAny,
complementing the existing toAny.

For UNO ABI reasons, these classes need to be CPPU_GCC_DLLPUBLIC_EXPORT (so
their RTTI symbols get exported), so they are careful to explicitly declare any
special member functions that would otherwise be declared implicitly, to mark
them CPPU_GCC_DLLPRIVATE. But for LIBO_INTERNAL_ONLY, we always use
-fvisibility-inlines-hidden (except for MSVC, where it doesn't matter, as
CPPU_GCC_DLLPRIVATE expands to nothing there, either), so can leave those
functions implicitly declared, so not to prevent move ctor and move assign op
from being implicitly declared.
This covers cid#s 1371143, 1371162, 1371185, 1371189, 1371290, and 1371308.

The issue of 362d4f0cd4e50111edfae9d30c90602c37ed65a2 "Explicitly mark
overriding destructors as 'virtual'" appears to no longer be a problem with
MSVC 2013.
(The little change in the rewriting code of compilerplugins/clang/override.cxx
was necessary to prevent an endless loop when adding "override" to
OOO_DLLPUBLIC_CHARTTOOLS virtual ~CloseableLifeTimeManager();
in chart2/source/inc/LifeTime.hxx, getting stuck in the leading
OOO_DLLPUBLIC_CHARTTOOLS macro. Can't remember what that
isAtEndOfImmediateMacroExpansion thing was originally necessary for, anyway.)

...which (in LIBO_INTERNAL_ONLY) for Clang expands to [[clang::fallthrough]] in
preparation of enabling -Wimplicit-fallthrough. (This is only relevant for
C++11, as neither C nor old C++ has a way to annotate intended fallthroughs.)
Could use BOOST_FALLTHROUGH instead of introducing our own SAL_FALLTHROUGH, but
that would require adding back in dependencies on boost_headers to many
libraries where we carefully removed any remaining Boost dependencies only
recently. (At least make SAL_FALLTHROUGH strictly LIBO_INTERNAL_ONLY, so its
future evolution will not have any impact on the stable URE interface.) C++17
will have a proper [[fallthroug]], eventually removing the need for a macro
altogether.

The Itanium C++ ABI mandates that for a unique (complete) C++ type a single
unique symbol for the type's RTTI name is used across a process's dynamic
objects (so type equivalence can be determined via pointer comparison on the
RTTI names).
GCC nowadays deviates from that, using strcmp to determine equivalence, so it is
resilient to RTTI names being bound locally within dynamic objects (which has
performance benefits, but also makes it impossible to have unrelated types that
happen to have the same name "encapsulated" in individual dynamic objects---
whether or not that would violate the ODR would be open to interpretation of how
dynamic objects fit into the C++ Standard).
LLVM sticks to the Itanium ABI, which becomes notable in at least two places:
For one, libc++abi's __dynamic_cast uses strict checking. It still has a
_LIBCXX_DYNAMIC_FALLBACK for now that additionally uses strcmp checking and
syslogs visibility violations. Mac OS X uses libc++abi with
_LIBCXX_DYNAMIC_FALLBACK enabled, and running LO routinely logs dynamic_cast
errors to the Console there.
For another, RTTI-based UBSan checks unconditionally only use strict checking
(cf. isDerivedFromAtOffset in lib/ubsan/ubsan_type_hash.cc). This causes false
positives from Clang -fsanitize=function and -fsanitize=vptr even on Linux not
using libc++abi.
Therefore, introduce SAL_DLLPUBLIC_RTTI to mark types for which RTTI needs to
have default visibility under the Itanium/LLVM semantics. There is
unfortunately no way to mark only the (implicitly generated) RTTI symbols for
default visibility, but at least with the cases where SAL_DLLPUBLIC_RTTI is used
for now that is no real problem---any class type marked SAL_DLLPUBLIC_RTTI only
has inline (covered by -fvisibility-inlines-hidden) or undefined pure virtual
functions. It appears that even the vtables of those classes remain hidden, at
least with Mach-O on Mac OS X. (That also means there is no need for a
SAL_DLLPRIVATE_RTTI marker analoguous to the---also superfluous in retrospect---
CPPU_GCC_DLLPRIVATE one.)
Nevertheless, the number of exported symbols of course increases when
SAL_DLLPUBLIC_RTTI is "active." For a full-blown --enable-dbgutil build on Mac
OS X,
find instdir/LibreOffice.app/Contents -name \*.dylib\* -exec nm -gU {} \; \
wc -l
increased from 125541 to 139239. For Linux, an option might be to "activate"
SAL_DLLPUBLIC_RTTI only for __clang__ plus !ENABLE_RUNTIME_OPTIMIZATIONS.
The set of types marked SAL_DLLPUBLIC_RTTI with this patch (wholesale cppumaker-
generated UNO enum, struct, and interface types; plus some IEmbeddedHelper and
IUndoManager) is chosen so that a full "make check" on Mac OS X no longer
syslogs any dynamic_cast errors to the Console.
