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.

# Notice
vendor/bc: import version 6.2.0 This is a production release with a new feature and a few bug fixes. The bug fixes include: - A crash when bc and dc are built using editline, but history is not activated. - A missing local in the uint*() family of functions in the extended math library. - A failure to clear the tail call list in dc on error. - A crash when attempting to swap characters in command-line history when no characters exist. - SIGWINCH was activated even when history was not. The new feature is that stack traces are now given for runtime errors. In debug mode, the C source file and line of errors are given as well.
