Import new 2-clause BSD licenced implementation of the bc and dc commands

These implementations of the bc and dc programs offer a number of advantages
compared to the current implementations in the FreeBSD base system:

- They do not depend on external large number functions (i.e. no dependency
  on OpenSSL or any other large number library)

- They implements all features found in GNU bc/dc (with the exception of
  the forking of sub-processes, which the author of this version considers
  as a security issue).

- They are significantly faster than the current code in base (more than
  2 orders of magnitude in some of my tests, e.g. for 12345^100000).

- They should be fully compatible with all features and the behavior of the
  current implementations in FreeBSD (not formally verified).

- They support POSIX message catalogs and come with localized messages in
  Chinese, Dutch, English, French, German, Japanese, Polish, Portugueze,
  and Russian.

- They offer very detailed man-pages that provide far more information than
  the current ones.

# `bc`
[![Build Status][13]][14]
[![codecov][15]][16]
[![Coverity Scan Build Status][17]][18]
***WARNING: This project has moved to [https://git.yzena.com/][20] for [these
reasons][21], though GitHub will remain a mirror.***
This is an implementation of the [POSIX `bc` calculator][12] that implements
[GNU `bc`][1] extensions, as well as the period (`.`) extension for the BSD
flavor of `bc`.
For more information, see this `bc`'s [full manual][2].
This `bc` also includes an implementation of `dc` in the same binary, accessible
via a symbolic link, which implements all FreeBSD and GNU extensions. (If a
standalone `dc` binary is desired, `bc` can be copied and renamed to `dc`.) The
`!` command is omitted; I believe this poses security concerns and that such
functionality is unnecessary.
For more information, see the `dc`'s [full manual][3].
This `bc` is Free and Open Source Software (FOSS). It is offered under the BSD
2-clause License. Full license text may be found in the [`LICENSE.md`][4] file.
## Prerequisites
This `bc` only requires a C99-compatible compiler and a (mostly) POSIX
2008-compatible system with the XSI (X/Open System Interfaces) option group.
Since POSIX 2008 with XSI requires the existence of a C99 compiler as `c99`, any
POSIX and XSI-compatible system will have everything needed.
Systems that are known to work:
* Linux
* FreeBSD
* OpenBSD
* NetBSD
* Mac OSX
* Solaris
* AIX
Please submit bug reports if this `bc` does not build out of the box on any
system besides Windows. If Windows binaries are needed, they can be found at
[xstatic][6].
## Build
This `bc` should build unmodified on any POSIX-compliant system.
For more complex build requirements than the ones below, see the
[build manual][5].
### Pre-built Binaries
It is possible to download pre-compiled binaries for a wide list of platforms,
including Linux- and Windows-based systems, from [xstatic][6]. This link always
points to the latest release of `bc`.
### Default
For the default build with optimization, use the following commands in the root
directory:
```
./configure.sh -O3
make
```
### One Calculator
To only build `bc`, use the following commands:
```
./configure.sh --disable-dc
make
```
To only build `dc`, use the following commands:
```
./configure.sh --disable-bc
make
```
### Debug
For debug builds, use the following commands in the root directory:
```
./configure.sh -g
make
```
### Install
To install, use the following command:
```
make install
```
By default, `bc` and `dc` will be installed in `/usr/local`. For installing in
other locations, use the `PREFIX` environment variable when running
