This is a prerequisite for making conversion from OUStringLiteral to OUString
more efficient at least for C++20 (by replacing its internals with a constexpr-
generated sal_uString-compatible layout with a SAL_STRING_STATIC_FLAG refCount,
conditionally for C++20 for now).
For a configure-wise bare-bones build on Linux, size reported by `du -bs
instdir` grew by 118792 bytes from 1155636636 to 1155755428.
In most places just a u"..." string literal prefix had to be added. In some
places
char const a[] = "...";
variables have been changed to char16_t, and a few places required even further
changes to code (which prompted the addition of include/o3tl/string_view.hxx
helper function o3tl::equalsIgnoreAsciiCase and the additional
OUString::createFromAscii overload).
For all uses of macros expanding to string literals, the relevant uses have been
rewritten as
u"" MACRO
instead of changing the macro definitions. It should be possible to change at
least some of those macro definitions (and drop the u"" from their call sites)
in follow-up commits.

The main reason for the "home-grown" UpCast introduced with
904b3d1fce "Up-cast conversion constructor for
css::uno::Reference" in 2013 was probably that we could not yet rely on C++11
std::is_base_of back then. A (welcome) side effect was that the derived class
could be incomplete.
However, specializations of UpCast relying on whether or not T2 is incomplete
are obviously an ODR violation if the type is incomplete in some TUs and
complete (and derived from T1) in others. And even if UpCast had internal
linkage, it would still be brittle that its behavior depends on the completeness
of T2 at the point of the template's instantiation, and not necessarily at the
point of use.
That means we should better base that ctor on std::is_base_of (which we can do
now since 39a1edd6fe "Make css::uno::Reference
upcast ctor LIBO_INTERNAL_ONLY"), which causes a compilation error at least on
Clang and GCC if the completeness requirements are not met. This change fixes
all the cases where types need to be complete now, plus any resulting
loplugin:referencecasting warnings ("the source reference is already a subtype
of the destination reference").

"Find explicit casts from signed to unsigned integer in comparison against
unsigned integer, where the cast is presumably used to avoid warnings about
signed vs. unsigned comparisons, and could thus be replaced with
o3tl::make_unsigned for clairty." (compilerplugins/clang/unsignedcompare.cxx)
o3tl::make_unsigned requires its argument to be non-negative, and there is a
chance that some original code like
static_cast<sal_uInt32>(n) >= c
used the explicit cast to actually force a (potentially negative) value of
sal_Int32 to be interpreted as an unsigned sal_uInt32, rather than using the
cast to avoid a false "signed vs. unsigned comparison" warning in a case where
n is known to be non-negative. It appears that restricting this plugin to non-
equality comparisons (<, >, <=, >=) and excluding equality comparisons (==, !=)
is a useful heuristic to avoid such false positives. The only remainging false
positive I found was 0288c8ffec "Rephrase cast
from sal_Int32 to sal_uInt32".
But which of course does not mean that there were no further false positivies
that I missed. So this commit may accidentally introduce some false hits of the
assert in o3tl::make_unsigned. At least, it passed a full (Linux ASan+UBSan
--enable-dbgutil) `make check && make screenshot`.
It is by design that o3tl::make_unsigned only accepts signed integer parameter
types (and is not defined as a nop for unsigned ones), to avoid unnecessary uses
which would in general be suspicious. But the STATIC_ARRAY_SELECT macro in
include/oox/helper/helper.hxx is used with both signed and unsigned types, so
needs a little oox::detail::make_unsigned helper function for now. (The
ultimate fix being to get rid of the macro in the first place.)

...following up on 314f15bff0 "Extend
loplugin:external to warn about enums".
Cases where free functions were moved into an unnamed namespace along with a
class, to not break ADL, are in:
filter/source/svg/svgexport.cxx
sc/source/filter/excel/xelink.cxx
sc/source/filter/excel/xilink.cxx
svx/source/sdr/contact/viewobjectcontactofunocontrol.cxx
All other free functions mentioning moved classes appear to be harmless and not
give rise to (silent, even) ADL breakage. (One remaining TODO in
compilerplugins/clang/external.cxx is that derived classes are not covered by
computeAffectedTypes, even though they could also be affected by ADL-breakage---
but don't seem to be in any acutal case across the code base.)
For friend declarations using elaborate type specifiers, like
class C1 {};
class C2 { friend class C1; };
* If C2 (but not C1) is moved into an unnamed namespace, the friend declaration
must be changed to not use an elaborate type specifier (i.e., "friend C1;"; see
C++17 [namespace.memdef]/3: "If the name in a friend declaration is neither
qualified nor a template-id and the declaration is a function or an
elaborated-type-specifier, the lookup to determine whether the entity has been
previously declared shall not consider any scopes outside the innermost
enclosing namespace.")
* If C1 (but not C2) is moved into an unnamed namespace, the friend declaration
must be changed too, see <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71882>
"elaborated-type-specifier friend not looked up in unnamed namespace".
Apart from that, to keep changes simple and mostly mechanical (which should help
avoid regressions), out-of-line definitions of class members have been left in
the enclosing (named) namespace. But explicit specializations of class
templates had to be moved into the unnamed namespace to appease
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92598> "explicit specialization of
template from unnamed namespace using unqualified-id in enclosing namespace".
Also, accompanying declarations (of e.g. typedefs or static variables) that
could arguably be moved into the unnamed namespace too have been left alone.
And in some cases, mention of affected types in blacklists in other loplugins
needed to be adapted.
And sc/qa/unit/mark_test.cxx uses a hack of including other .cxx, one of which
is sc/source/core/data/segmenttree.cxx where e.g. ScFlatUInt16SegmentsImpl is
not moved into an unnamed namespace (because it is declared in
sc/inc/segmenttree.hxx), but its base ScFlatSegmentsImpl is. GCC warns about
such combinations with enabled-by-default -Wsubobject-linkage, but "The compiler
doesn’t give this warning for types defined in the main .C file, as those are
unlikely to have multiple definitions."
(<https://gcc.gnu.org/onlinedocs/gcc-9.2.0/gcc/Warning-Options.html>) The
warned-about classes also don't have multiple definitions in the given test, so
disable the warning when including the .cxx.
