Обсуждение: [HACKERS] src/test/ssl/t/001_ssltests.pl should not tromp on file permissions

I got tripped up while building the 10beta1 tarballs by the fact
that src/test/ssl/ssl/client.key had permissions 0600 in my git
checkout.  After a fair amount of head-scratching, I figured out
that this must have been a side-effect of having run the SSL regression
tests at some point in the past.  I do not like test scripts that
scribble on non-transient files, not even (or perhaps especially not)
if they're "just" changing the permissions.

We could maybe make 001_ssltests.pl save and restore the file's
permissions, but I think probably a cleaner answer is to have it
make a temporary copy and set the permissions on that.

Thoughts?

Ah, you are talking about ss/client.key here... Using a temporary copy
makes the most sense to me, as there is no need to think about putting
back the old permissions on test failure, and the original tree
remains unmodified all the time.

Pushed with minor adjustments --- I made the test script unlink the temp
file at the end, and tightened the .gitignore patterns a bit.
