extfs: tester: let test scripts easily access configure-time parameters.

[mooffie]

This patch introduces a mechanism by which tests can easily access configure-time parameters, like @PERL@, @AWK@, etc.

(The traditional method, of *.in files, can still be used of course, but this mechanism is more comfortable.)

Rationale

As seen in #3751, tests should have access to configure-time parameters. After committing this patch, the file 'data/rpm.rewrite.sh' could be written as follows:

. "$MC_TEST_EXTFS_CONFIG_SH"

blah_blah_blah()
{
  $PERL -e 'whatever perl code'
}

I have convened with Andrew earlier this week, and we both agree that on the basis of your contributions you should be granted commit access to the source repository (a long time ago ;-) ). Today, I have cleaned up our GitHub organization settings and sent you an invitation to join the committers team. If anything, this will save us all a lot of time posting patches to Trac & creating branches from them. What do you think?

In terms of workflows, I believe that you might have followed our conversation with Egmont on the mailing list, and I hope that this also works for you... I'd be happy to discuss whatever you think is worth being discussed and help you if you need any help, but vacation time is over, and so I will be able to make as much time than I spent in the last couple of weeks :-/

Andrew and Yury: thank you for your vote of confidence!

What do you think?

Superb.

In terms of workflows, I believe that you might have followed our conversation with Egmont on the mailing list,

Yes.

​This post (and ​this one) contains everything.

I already started the workflow for #3752 (which blocks this ticket). Once I merge that one I'll handle this ticket.

(I won't be here till Sunday.)

Awesome!
