contrib/bc: merge version 5.1.0 from vendor branch

Browse Source 
This version adds options and functions that allow to print numbers
in the open interval (-1 .. 1) with or without a leading 0 digit.

Additionally, an option has been added to prevent line wrap and
allows to print arbitrarily long results on a single line.

# News # News
## 5.1.0
This is a production release with some fixes and new features.
* Fixed a bug where an `if` statement without an `else` before defining a
function caused an error.
* Fixed a bug with the `bc` banner and `-q`.
* Fixed a bug on Windows where files were not read correctly.
* Added a command-line flag (`-z`) to make `bc` and `dc` print leading zeroes on
numbers `-1 < x < 1`.
* Added four functions to `lib2.bc` (`plz()`, `plznl()`, `pnlz()`, and
`pnlznl()`) to allow printing numbers with or without leading zeros, despite
the use of `-z` or not.
* Added builtin functions to query global state like line length, global stacks,
and leading zeroes.
* Added a command-line flag (`-L`) to disable wrapping when printing numbers.
* Improved builds on Windows.
