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.

Convert Mk/bsd.cran.mk to the Uses framework.

PR:		ports/184699
Reviewed by:	bapt
Approved by:	portmgr (bdrewery), wen (maintainer, timeout > 2 weeks)

Add stage support to Mk/bsd.cran.mk and all USE_R_MOD ports (aka R-cran-*).

Since this patch converts all affected ports, bsd.cran.mk no longer supports
NO_STAGE and errors out if NO_STAGE is set.

  One of the aims of this package is to make life easier for useRs
  who deal with survey data sets. It provides an infrastructure for
  the management of survey data including value labels, definable
  missing values, recoding of variables, production of code books,
  and import of (subsets of) SPSS and Stata files. Further, it provides
  functionality to produce tables and data frames of arbitrary
  descriptive statistics and (almost) publication-ready tables of
  regression model estimates. Also some convenience tools for graphics,
  programming, and simulation are provided.
