The hash field in the picture-structure was in principle non-operational.
It was set on loading, but never actually changed. The authoritative
hash comes from the filename->hash map.
Therefore, make this explicit by removing the hash field from the
picture structure.
Instead of filling the picture structure on loading, add the
hash directly to the filename->hash map. This is done in the
register_hash() function, which does not overwrite old entries.
I.e. the local hash has priority over the save-file. This
policy might be refined in the future.

learnHash() was always called in conjunction with add_hash(). The
pattern was that a local filename and a hash were connected in
the hash-to-filename and the filename-to-hash maps. Then, the
original picture-filename or url were registered in the filename-to-hash
map.
This commit changes learnHash() to take three parameters (original-filename,
local-filename and hash) and do all of the above. The new code is
simpler because no dummy picture struct has to be generated in
DiveListView::loadImageFromURL().
The tests were extended to check for all hash<->filename associations.

learnHash() is called either on a local picture structure
[DiveListView::loadImageFromURL()] or on a cloned picture structure
[ImageDownloader::saveImage()]. In neither case the picture structure
is passed to the frontend. Therefore, storing the new hash in the
picture struct is not necessary.

Add one more picture to the already existing test.
This new picture is a JPEG and has data after JFIF EOI tag.

Update tests with a (compile time) option SUBSURFACE_TEST_DATA,
pointing to test data base path. It is needed for cross compilation cases.
SUBSURFACE_TEST_DATA is set to SUBSURFACE_SOURCE by default,
or configurable via cmake option -DSUBSURFACE_TEST_DATA="...".
