archivers: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

Could not be committed due to merge conflict:
devel/py-traitlets/distinfo

The following distfiles were unfetchable (note: some may be only fetched
conditionally):

./devel/pvs/distinfo pvs-3.2-solaris.tgz
./devel/eclipse/distinfo eclipse-sourceBuild-srcIncluded-3.0.1.zip

Log message:
devel: Remove SHA1 hashes for distfiles

Log message:
mark packages that fail with -Werror=char-subscripts

These packages are susceptible to bugs when confronted with non-ASCII
characters.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94182.

It takes some time to analyze and fix these individually, therefore they
are only marked as "needs work".

Log message:
Follow some redirects.

Log message:
Add SHA512 digests for distfiles for devel category

Issues found with existing distfiles:
	distfiles/eclipse-sourceBuild-srcIncluded-3.0.1.zip
	distfiles/fortran-utils-1.1.tar.gz
	distfiles/ivykis-0.39.tar.gz
	distfiles/enum-1.11.tar.gz

	distfiles/pvs-3.2-linux.tgz
	distfiles/pvs-3.2-solaris.tgz
	distfiles/pvs-3.2-system.tgz
No changes made to these distinfo files.

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
add a bit of a hack that should fix or advance the MacOS build

Log message:
Import mcpp-2.7.2 as devel/mcpp.

mcpp is a C/C++ preprocessor with the following features.

* Implements all of C90, C99 and C++98 specifications.
* Provides a validation suite to test C/C++ preprocessor's conformance
and quality comprehensively. When this validation suite is applied,
mcpp distinguishes itself among many existing preprocessors.
* Has plentiful and on-target diagnostics to check all the
preprocessing problems such as latent bug or lack of portability
in source code.  * Has #pragma directives to output debugging
information.
* Is portable and has been ported to many compiler-systems, including
GCC and Visual C++, on UNIX-like systems and Windows.
* Has various behavior modes.
* Can be built either as a compiler-specific preprocessor to replace
the resident preprocessor of a particular compiler system, or as
a compiler-independent command, or even as a subroutine called from
some other main program.
* Provides comprehensive documents both in Japanese and in English.
* Is an open source software released under BSD-style-license.
