When the typelib_TypeDescription is null, the following code would dereference a
null pointer anyway (but which doesn't necessarily cause an immediate crash on
some platforms like Wasm, so better be explicit). (Also, leave those checks out
of functions like uno_type_sequence_realloc, which would have been preceded by a
call to one of the functions creating a sequence of the given type, and which
would thus already have detected failure to obtain the relevant type
information.)

c-family: don't warn for [[maybe_unused]] on data member
The C++17 standard (and C2x) says that [[maybe_unused]] may be applied to a
non-static data member, so we shouldn't warn about it. And I don't see a
reason not to handle a FIELD_DECL the same as any other decl, by setting
TREE_USED on it. It doesn't look like anything yet cares about that flag on
a FIELD_DECL, but setting it shouldn't hurt.
gcc/c-family/ChangeLog:
* c-attribs.c (handle_unused_attribute): Handle FIELD_DECL.
gcc/testsuite/ChangeLog:
* g++.dg/ext/attrib62.C: No longer warn.
* g++.dg/diagnostic/maybe_unused1.C: New test.
gcc/ChangeLog:
* doc/extend.texi (unused variable attribute): Applies to
structure fields as well.

loplugin:fakebool (as the relevant reinterpret_cast to silence some occurrences
is no longer seen "inline" now), and the heuristics of loplugin:unused no longer
worked (also because of the now-hidden reinterpret_cast'ing), but adding a
maybe_unused attribute looks better than tweaking that plugin's heuristics even
further.

...for LIBO_INTERNAL_ONLY, instead of having them as additional overloads. That
way, loplugin:bufferadd and loplugin:stringviewparam found many further
opportunities for simplification (all addressed here). Some notes:
* There is no longer an implicit conversion from O[U]String to O[U]StringBuffer
(as that goes via user-defined conversions through string_view now), which was
most noticeable in copy initializations like
OStringBuffer buf = someStr;
that had to be changed to direct initialization,
OStringBuffer buf(someStr);
But then again, it wasn't too many places that were affected and I think we can
live with that.
* I made the O[U]StringBuffer ctors taking string_view non-explicit, mainly to
get them in line with their counterparts taking O[U]String.
* I added an OUStringBuffer::lastIndexOf string_view overload that was missing
(relative to OUStringBuffer::indexOf).
* loplugin:stringconstant needed some addition to keep the
compilerplugins/clang/test/stringconstant.cxx checks related to
OStringBuffer::append and OStringBuffer::insert working.
* loplugin:stringviewparam no longer needs the special O[U]StringBuffer-related
code that had been introduced in 1250aecd71

...compared to a full-blown O[U]String, for temporary objects holding an
O[U]StringConcat result that can then be used as a std::[u16]string_view.
It's instructive to see how some invocations of operator ==, operator !=, and
O[U]StringBuffer::insert with an O[U]StringConcat argument required implicit
materialization of an O[U]String temporary, and how that expensive operation has
now been made explicit with the explicit O[U]StringConcatenation ctor.
(The additional operator == and operator != overloads are necessary because the
overloads taking two std::[u16]string_view parameters wouldn't even be found
here with ADL. And the OUString-related ones would cause ambiguities in at
least sal/qa/rtl/strings/test_oustring_stringliterals.cxx built with
RTL_STRING_UNITTEST, so have simply been disabled for that special test-code
case.)

...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.
