Deprecate ports broken for more than 6 months

Bump 46 ports depending on math/openblas because the after the recent
math/openblas update the library name changed in openblas.

Fix math/openblas and bump dependent ports

* Fix build on i386 [1]
* Fix science/code_saturne build with new openblas [2]
* Avoid installing private headers [3]
* Prevent build from optimizing for host by correcting build confg [4]
* Bump portrevision of dependent ports [5]

This is correcting issues from r523749 [1][2][4] and r515970 [3]

Update devel/cmake to latest upstream release, 3.16.2

This new release has support for the latest Boost, Objective-C
and various small improvements. The release notes are at:
	https://cmake.org/cmake/help/v3.16/release/3.16.html

Two ports could not be persuaded to build with this new release
(math/openmesh science/fleur) and are marked BROKEN. Other build
fixes have already been done in-tree.

Thanks antoine@ for the exp-runs (multiple).
Thanks tcberner@ for prep-work (most of the work, actually).

science/fleur: Spell HDF5_CMAKE_ON correctly

Untested since the option is marked as broken.

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.

Related to revision 499061 bump ports with USES=fortran to have them
benefit from the improved situation where libgcc_s is only used when
absolutely necessary.

Change cmake default behaviour to outsource.

Ports that build out of source now simply can use "USES=cmake"
instead of "USES=cmake:outsource". Ports that fail to build
out of source now need to specify "USES=cmake:insource".

I tried to only set insource where explictely needed.
