vendor/bc: upgrade to version 7.0.0

This is a production release to fix three bugs, none of which
affects well formed scripts on FreeBSD:

The first bug is that bc/dc will exit on macOS when the terminal
is resized.

The second bug is that an array, which should only be a function
parameter, was accepted as part of larger expressions.

The third bug is that the value stack for dc was cleared on any error.
However, this is not how other dc behave. To bring dc more in line
with other implementations, this behavior was changed. This change is
why this version is a new major version.

contrib/bc: merge from vendor release 6.2.2

This update fixes a few issues in history editing and the processing
of the "quit" function. The "quit" function will no longer cause bc
to exit when encountered in a script file (before any command from
the script has been executed).

New functions is_number(), is_string return 1 if the passed argument
is a number resp. a string. The asciify() function has been extended
to support the conversion of an array of numbers into a string.

usr.bin/bc: update to version 5.3.1

This version adds support for command line editing and history using
the libedit or readline libraries in addition to the line editing
features available in previous versions.

The version in the base system is configured to use libedit.

This allows to choose between emacs and vi line editing commands and
to use command overrides via a ~/.editrc file.
