usr.bin/ghä-bc, contrib/bc: update to version 5.0.0

Merge commit 2f57ecae4b98e76e5d675563785a7e6c59c868c4

This is a new major release with a number of changes and extensions:

- Limited the number of temporary numbers and made the space for them
  static so that allocating more space for them cannot fail.
- Allowed integers with non-zero scale to be used with power, places,
  and shift operators.
- Added greatest common divisor and least common multiple to lib2.bc.
- Made bc and dc UTF-8 capable.
- Added the ability for users to have bc and dc quit on SIGINT.
- Added the ability for users to disable prompt and TTY mode by
  environment variables.
- Added the ability for users to redefine keywords.
- Added dc's modular exponentiation and divmod to bc.
- Added the ability to assign strings to variables and array elements
  and pass them to functions in bc.
- Added dc's asciify command and stream printing to bc.
- Added bitwise and, or, xor, left shift, right shift, reverse,
  left rotate, right rotate, and mod functions to lib2.bc.
- Added the functions s2u(x) and s2un(x,n), to lib2.bc.
