contrib/bc: MFC version 5.2.2

This release assigns a default value to the internal program name
variable in case the program is invoked with argv[0] == NULL.

There was no security issue: the prevuous program version would have
been immediately terminated due to a NULL dereference.

contrib/bc: remove files ommitted from the release

A number of files have been removed from the release distribution of
this bc implementation. They were mostly relevant for pre release
testing and benchmarking to identify regressions. The Markdown
sources of the man pages are only relevant for combinations of build
options not used in FreeBSD and need non-default conversion tools
(available as ports in FreeBSD).

All the omitted files can be found in the upstream git repository,
and they are fetched when building this software as a port. But they
have never been used in the FreeBSD base system.

contrib/bc: merge version 5.1.0 from vendor branch

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.

contrib/bc: temporarily disconnect the tests for 5.0.2

The tests that come with version 5.0.2 have been extended to cover the
line editing functions. It has been found that these tests generate
false negative results in FreeBSD, most likely due to an issue in the
pexpect functionality used.

These history tests are skipped on systems that do not have python and
py-pexpect installed (and thus are unlikely to cause CI test failures),
but in order to not cause irritating failures on systems were these
packages are in fact installed, I temporarily disconnect them.

I had planned to skip this version due to the issue with the history
tests, but some committer has asked me to go ahead since the currently
used version 5.0.0 contains a macro name that collides with a project
he is working on.

No MFC of this version is planned. A version 5.0.3 is expected to be
released soon, and that version will allow to reconnect the tests and
will be MFCed.

[bc] Update to version 4.0.0

This version fixes an issue (missing pop of top-of-stack value in the
"P" command of the dc program).

This issue did not affect the bc program, since it does not use dc as
an back-end to actually perform the calculations as was the case with
the traditional bc and dc programs.

The major number has been bumped due to Windows support that has been
added to this version. It does not correspond to a major change that
might affect FreeBSD.

Vendor import of Gavin Howard's bc version 3.2.6

(cherry picked from commit 47a52dc4d48f259ab7d9f9ba6b65f4f2331a22dc)

Second attempt after revert of a previous commit that affected files
with similar names in unrelated directories.

Thanks go to Martin Birgmaier for reporting the issue and identifying
the cause of git getting confused: files from the root of the vendor
files were associated with files in the FreeBSD base root directory.

Martin Birgmaier points out that to make this cherry-pick succeed,
the option -Xsubtree=contrib/bc has to be passed to prevent files
outside that path to be considered.

Revert "bc: Vendor import of Gavin Howard's bc version 3.2.6"

This reverts commit 601ac82194693fcae9d7d2a7ec7d66ebaf3fd61e.

Seems that git cherry-pick mis-merges files for this software.
It associates files in completely unrelated sub-trees with same name
files from this package, e.g. README.md and .gitignore.

My attempt to fix the mis-merge was incomplete and wrong.
Therefore I'm reverting the commit that as a result of my failed
attempt at conflict resolution lead to README.md and .gitignore
in the top source directory to be deleted.

This mistake has been carried over to releng/13.0, which now
also lacks README.md and .gitignore in /usr/src.

I'll try to re-apply the failed commit over the next hours and to get
the fix merged to releng/13.0 with re approval.

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.

The upstream sources contain a large number of tests, which are not
imported with this commit. They could be integrated into our test
framework at a latter time.

Installation of this version is controlled by the option "MK_GH_BC=yes".
This option will be set to yes by default in 13-CURRENT, but will be off
by default in 12-STABLE.
