Re-apply part of r559792 (INDEX and bulk -a OK)

With hat:	portmgr

Revert r559792 to unbreak INDEX and bulk -a
It seems a lot of reverse dependencies were missed

With hat:	portmgr

Remove most expired ports that depend on Python 2.7:

Exceptions are:
- mail/mailman, our listservers still use it
- www/chromium, solely because of popular demand,
  upstream is (slowly) working on porting it to Python 3
- ports that have actual patches for Python 3 against
  them (Cinnamon and a few unrelated other ports)
- llvm70 and qt5-webengine because they seem to have a lot
  of dependencies which need further analysis
- sysutils/uefi-edk2-bhyve because bhyve seems to use them
- python2 and python27 themselves

I'm sure there will be complaints, but the nice thing about
a version control system is that we can revert and adjust things.

security/sandsifter: extend lifespan, upstream is working on py3 support.

Deprecate some ports using deprecated version of python

With hat:	portmgr

Bump the Capstone library version to 4

This port is dependant on both the Capstone library and the Python
bindings for Capstone. The version of the library has to be bumped to 4 as
the bindings version has to be kept in sync with the library version in
order to avoid build problems.

security/sandsifter: update to 1.04

Restrict this port to Python 2.7 for now, work to get it running
with Python 3.6 is in progress upstream.

Pet portlint (remove an extraneous spacae from pkg-descr)

UCL-ify pkg-message of my ports.

security/sandsifter: update to version 1.03

This version is based on a fork of the original repository (which was
itself a fork) and is the same fork that Debian and Ubuntu use. The
previous repository is no longer under development.

Some binaries have been renamed by the new upstream.

Extend pkg-messsage with some more usage instructions.

This adds a license (BSD3CLAUSE) and a slightly extended README.

Pet portlint while here.

The sandsifter audits x86 processors for hidden instructions and
hardware bugs, by systematically generating machine code to search
through a processor's instruction set, and monitoring execution for
anomalies. Sandsifter has uncovered secret processor instructions from
every major vendor; ubiquitous software bugs in disassemblers,
assemblers, and emulators; flaws in enterprise hypervisors; and both
benign and security-critical hardware bugs in x86 chips.
