[tclwebtest] Big patch with multiple enhacements

[Grzegorz A. H. <gr...@ef...>]

Hi.

I'm attaching the following patch which would effectively synchronize
my personal CVS copy of tclwebtest with SF. It includes several
improvements:

-adding noredirect parameter to do_request, useful to debug step
by step server cookies.

-do_request returns the url it has reached, same as [response url]
except it can have a different value if the request fails or you
are using -noredirect.

-catch of geturl socket failure and translated to human readable form

-corrected bug in regex of post_process_url

-memory strings, no temporary files during execution

-separation of test execution in a smaller function which can be
called recursively to simulate the source command

-example of the above with db_source, a special version of source
which looks into a database

-identation of child scripts run with db_source

Til, tell me what you want me to patch into SourceForge (obviously
the db_source set of commands is very specific of my needs, but it
could be left commented as example for other developers?), some of
these patches are still pending of approval in the mailing list.
