Chase shlib version bump of `graphics/lensfun' (r524150).

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

graphics/photivo: remove flavors (Qt4 deprecation)

graphics/photivo: prepare for exiv2-0.27

PR:		235943

Fix Qt5 symbol version scripts to put the catch-all clause first.  When
a symbol matches multiple clauses the last one takes precedence.  If the
catch-all is last it captures everything.  In the case of Qt5 libraries
this caused all symbols to have a Qt_5 label while some should have
Qt_5_PRIVATE_API.  This only affects lld because GNU ld always gives the
catch-all lowest priority.

Older versions of Qt5Webengine exported some memory allocation symbols from
the bundled Chromium.  Version 5.9 stopped exporting these [1] but the
symbols were kept as weak wrappers for the standard allocation functions to
maintain binary compatibility. [2][3]  The problem is that the call to the
standard function in these weak wrappers is only resolved to the standard
function if there's a call to this standard function in other parts of
Qt5Webengine, because only then is there a non-weak symbol that takes
precedence over the weak one.  If there's no such non-weak symbol the call

Use regular DEPRECATED and EXPIRATION_DATE variables in an "if FLAVOR" block
instead of flavoring the variables themselves. This caused too much hassle
for Tools/scripts/rmport.

Allow to build `graphics/photivo' against Qt 4, but keep Qt 5 enabled by
default to avoid needless package rebuilds.  (I was not able to reproduce
the build failure originally mentioned in r428684.)

- Fix build on 9.x by specifying proper c++ standard requirement and adding
missing include

Add a port of Photivo, a free and open source photo processor.

Unfortunately, I had to deprive it from using OpenMP features, since
`compiler:openmp' pulls in GCC and libstdc++ which causes linking
problems due to incompatible std::string ABI.  Also, while Qt 4.x
should be supported, it does not build against, so sadly it's Qt 5.x
based only for now.
