This avoids a hang approximately 1% of the time when running the test
suite on StatelessOpenPGP.
Since I've not seen git-annex hang when running git like that, I guess
git probably does something that avoids hanging similarly. Still, fixed
the same problem in Utility.Gpg too.

Test a specified Stateless OpenPGP command with eg:
git-annex test --test-git-config annex.shared-sop-command=sqop
Also documented that config and another one, but so far only the test suite
uses the configs, have not yet implemented using it for actual symmetric
encryption.

This aims to future-proof gpg key generation. OpenPGP is in flux with a
conflict over standards ongoing. It seems not unlikely that different
systems will have different gpg commands that support different algorithms.
This also simplifies the code by using the --quick-gen-key interface rather
than the experimental batch interface. It seems less likely that
--quick-gen-key will break than an experimental interface (whose
documentation I can no longer find).
--quick-gen-key is supported since gpg 2.1.0 (2014).

The old code traversed the list of addtreeitems once per subdirectory in
the tree, so could get quite slow. Converting to Map lookups sped it up
significantly.
In my test case, git-annex import used to take about 2 minutes, when
calling adjustTree to add back excluded files to the imported tree. This
dropped it down to 6 seconds. Of which 4 seconds are the actual
enumeration of the contents of the remote, so really only 2 seconds for
this.
The path prefix map is a bit suboptimal memory-wise, since items get
stored in the map once per subdirectory on the path to the item. It
would perhaps be better to use a tree data structure.
Also it's suboptimal memory-wise that it builds two maps, as well
as retaining a reference to addtreeitems. I could not see a way around
that though.

I saw a nearly 2 minute speed up from this, in a repo with 56000 files some
of which are preferred content of the special remote and others not. In
such a case, addBackExportExcluded has to do a lot of work, which is
unncessary when the tree is unchanged.
When using sync --content, preferred content checking of that many files
takes about 1 minute. So this speeds up sync --content by 3x.
When using git-annex import, the speed up is much larger.

Thanks to previous work in 11cc9f1933,
this is almost entirely free, it only needs to do some additional map
lookups and math.
The strictness annotations keep the memory use from blowing up.
