...warning about (for now only) functions and variables with external linkage
that likely don't need it.
The problems with moving entities into unnamed namespacs and breaking ADL
(as alluded to in comments in compilerplugins/clang/external.cxx) are
illustrated by the fact that while
struct S1 { int f() { return 0; } };
int f(S1 s) { return s.f(); }
namespace N {
struct S2: S1 { int f() { return 1; } };
int f(S2 s) { return s.f(); }
}
int main() { return f(N::S2()); }
returns 1, both moving just the struct S2 into an nunnamed namespace,
struct S1 { int f() { return 0; } };
int f(S1 s) { return s.f(); }
namespace N {
namespace { struct S2: S1 { int f() { return 1; } }; }
int f(S2 s) { return s.f(); }
}
int main() { return f(N::S2()); }
as well as moving just the function f overload into an unnamed namespace,
struct S1 { int f() { return 0; } };
int f(S1 s) { return s.f(); }
namespace N {
struct S2: S1 { int f() { return 1; } };
namespace { int f(S2 s) { return s.f(); } }
}
int main() { return f(N::S2()); }
would each change the program to return 0 instead.

rtl/string.hxx and rtl/ustring.hxx both unnecessarily #include <sal/log.hxx> (and don't make use of it themselves), but many other files happen to depend on it.

...motivated by <https://gerrit.libreoffice.org/#/c/41565/2> adding dead code
at the end of a switch statement, after the last case's "break".
-Wunreachable-code appears to work well on Clang, while it appears to have no
effect on GCC.
Most of the affected places are apparently temporary/TODO/FIXME cases of
disabling code via "if (false)", which can be written with an extra set of
parentheses as "if ((false))" to silence -Wunreachable-code on Clang (which thus
needed loplugin:unnecessaryparen to be adapted accordingly). In some cases,
the controlling expression was more complex than just "false" and needed to be
rewritten by taking it out of the if statement to silence Clang.
One noteworthy case where the nature of the disabled code wasn't immediately
apparent:
Sep 12 16:59:58 <sberg> quikee, is that "if (false)" in
ScExponentialSmoothingDialog::ApplyOutput
(sc/source/ui/StatisticsDialogs/ExponentialSmoothingDialog.cxx) some work-in-
progress or dead code?
Sep 12 17:02:03 <quikee> sberg: WIP, but you can remove it
Sep 12 17:04:47 <sberg> quikee, I'll wrap the false in an extra set of
parentheses for now, to silence -Wunreachable-code (I wouldn't want to
remove it, as I have no idea whether I should then also remove the "Initial
value" comment preceding it)
Sep 12 17:07:29 <quikee> sberg: both are different ways to calculate the
"intital value"... so no
Another case where the nature of the dead code, following while (true) loops
without breaks, is unclear is sd/source/ui/remotecontrol/BluetoothServer.cxx,
where I added TODO markers to the workarounds that silence the warnings for now.
basic/source/sbx/sbxvalue.cxx had a variable of type double, of automatic
storage duration, and without an initalizer at the top of a switch statement.
Clang warning about it is arguably a false positive.
Apart from that, this didn't find any cases of genuinely dead code in the
existing code base.

std::unary_function is deprecated since C++11 and removed in C++17
90% done with regexp magic.
removed obsolete <functional> includes.
The std::unary_function base class was used in 3 places:
* chart2/source/tools/DataSeriesHelper.cxx: lcl_MatchesRole
is used in a std::not1 function helper who uses the members
return_type and argument_type.
- replace deprecated std::not1 with a lambda
* chart2/source/tools/ModifyListenerHelper.cxx:
lcl_weakReferenceToSame used the argument_type member in the
operator() parameter.
- inline the parameter type.
* xmloff/source/chart/SchXMLExport.cxx: lcl_SequenceToMapElement
used result_type and argument_type in operator().
- inline the types
Also fix compile error with gcc about finding std::for_each.
