if a port needs 2.x then set MODPY_VERSION=${MODPY_DEFAULT_VERSION_2}.
This commit doesn't change any versions currently used; it may be that
some ports have MODPY_DEFAULT_VERSION_2 but don't require it, those
should be cleaned up in the course of updating ports where possible.
Python module ports providing py3-* packages should still use
FLAVOR=python3 so that we don't have a mixture of dependencies some
using ${MODPY_FLAVOR} and others not.

bcal (Byte CALculator) is a REPL CLI utility for storage expressions,
unit conversions or address calculations. If you can't calculate the hex
address offset for (512 - 16) MiB, or the value when the 43rd bit of a
64-bit address is set mentally, bcal is for you.
It has a bc mode for general-purpose numerical calculations.
Features:
* evaluate arithmetic expressions involving storage units
* perform general purpose calculations (using bc)
* convert to IEC/SI standard data storage units
* interactive mode with the last valid result stored for reuse
* show the address in bytes
* show address as LBA:OFFSET
* convert CHS to LBA and vice versa
* base conversion to binary, decimal and hex
* custom sector size, max heads/cylinder and max sectors/track
