...which appears to be a good heuristic to identify functions that are either
unused or should better be declared just once in an include file. (It also
filters out SAL_DLLPUBLIC extern "C" function definitions, which are most likely
meant to be referenced dynamically via dlsym.)

since it only contains a single sal_Bool site now, and we want
to leave that alone since it's a copy of similar stuff in cppuhelper.

It appears that the C++ standard allows overriding destructors to be marked
"override," but at least some MSVC versions complain about it, so at least make
sure such destructors are explicitly marked "virtual."

It's not very efficient, because we generally end up copying it twice -
once into the parameter and again into the destination OUString.
So I create a clang plugin that finds such places and generates a
warning so that we can convert them to pass-by-reference.

...and subsumes not only the use of __builtin_expect in assert, but also the use
of __builtin_constant_p (nested) in htonl on Mac OS X.

...that would not lead to silent changes of the code. That is, it does not warn
about sal_Bool parameters of virtual functions, so that (not yet rewritten)
overrides do not silently become overloads instead.
The plugin is in store/ for now, because not all of the code has been cleaned up
yet.

...to be able to find problems like 6e0bdf04ad
"sal_Bool arg of SetUseImagesInMenus was abused to squeeze '2' through it"
earlier when converting occurrences of sal_Bool to bool.
Restricting this check to function call arguments avoids too much noise while
hopefully still catching all the relevant problems.
(This check partially overlaps the pointertobool check, so implicit conversions
from pointers to bool call arguments will now generate two loplugin warnings,
but that's harmless.)

...as found in Mac OS X' assert macro definition,

...that easily works around the problem that in a rewriter rewriting types of
VarDecls like
T x, y;
it would try to replace T twice. Also, keep the list of removals globally with
the (global) rewriter.

First, I updated the clang rewriter to do the conversion.
Then I lightly hand-tweaked the output for the few places where
the rewriter messed up, mostly when dealing with calls on "this".

It also warns about trivial (mis-)uses of 0/1 and sal_False/True like
while (1) { ... }
instead of
while (true) { ... }
which it can automatically rewrite.
It does not warn if the relevant code is inside a macro in a .h (i.e., C)
include file, nor when a string literal is used in the assert macro like
assert(!"this cannot happen");
