Reserve PROJNAME for a "human-readable" name.

Colon in STAGE will most probably confuse matcher and lead to corrupt
version data.

This should give better hint if built from a feature branch

For now the spelling has been decided "Fastfoo", not "Fast Foo", or
"FastFoo".

These have been moved to saturnin

The tool is mostly based on ini files; make this more obvious.

The version based on config.mk has been finalized to include more
features:

 *  Build variables are now defined in config.ini.
 *  The ini system can self-reference other keys (up to several levels).
 *  Some config (namely `ENV` section) can be overrided by environment
    variables.
 *  The installer is now more portable (ported to saturnin so far):
    everything can be defined in config.ini

After many changes in TF...

Once simple.sh has been cleaned up and simplified in previous ~10
commits, it turns out that all it does is manage subtests.

Reflect that in the name.

(Doc will be updated later.)

Support test folder structure where test, oracle and generated result
data are stored each in separate directory.  This makes it easier to
ensure legible diff output without cluttering the filenames too much.

Apparently leftover from earlier TF version.

They can be any executables now.

This was obviously a bug.

Previously the framework was silent in cases such as when enumeration
fails (maybe due to enum functions not implemented), returns nothing,
or if regex in TF_FILTER_SUBTEST leaves nothing.

Now it bails out on errorneous or empty enumeration, and adds debug
message if TF_FILTER_SUBTEST is "too hungry".

Also, intermediary lists are saved to file and left for artifact
collection.

Most changes are in tf_do_subtest.

 *   Separated setup/cleanup logic from test data collecting and
     execution/evaluation.

 *   Revamped the execution/evaluation logic in a new tool testflt,
     allowing tester to use it as the need be.

 *   Code to compose actual test command removed, as testflt makes it
     easy to write the code in one place (TF_RUN) and keep simple things
     simple.

 *   Removed tf_parse_meta, as it's obsolered by above changes.

 *   Updated tests to reflect the new style.

(Thx Joe Spolsky for inspiration)

Apparently leftover from earlier changes, these files are exact
duplicates of their .oracle counterpart, but are not actually used by
local TF_RUN

...so that it can be understood by future reader.

Avoiding using the plain test name makes it easier to understand the
role of each file.
