bug#20986: tap-driver.sh replacement

[Arthur Schwarz]

The existing tap-driver.sh has flaws in detecting TAP input. The replacement
file removes all flaws, accepts the complete TAP Standard, and
1: Has extensive diagnostic messaging,
2: Is resilient to errors, 
3: Modular design,
4: Is documented,
5: Executes a suite of tests successfully,
6: etc.

I have previously assigned a copyright of stuff to the FSF, hopefully it
applies to this submission as well.

tap_setup.tar.xz has:
configure.ac     Autoconf configure file used
Makefile.am      root directory Makefile
buildscript.sh   The script I use to build and execute the tests
src/Makefile.am  TAP and a suite of 14 tests

tap_driver-0.5.tar.xz distribution tarball

The replacement version has one strong variance with the existing version.
The '--ignore-exit' option is ignored. I've looked at the implementation and
there is no rationale given stating its requirement or what issue is
resolved with it being present. At issue is that the implementation is
affected by its inclusion. So, it aint there.

The current implementation suffers from some issues. I believe all
outstanding issues are resolved with the new version.

Documentation for the test section, including complete documentation for
TAP, is included in another message (Replacing "15 Support for test
suites"). The document sent is some 100K and I realize is presents an issue.
