much better handling of arrayimage cli args
...
we were not setting the access hint on arrayimage args, so
arrayjoin "$(echo *.jpg)" x.tif[bigtiff] --across 10
would open all the jpg images to memory, usually, in random mode
now arrayimage args see the operation's access hint (seq in this case),
for much better behaviour
also, we allow any whitespace as an arg separator in arrayimage from
string

easier to adjust for smaller effects

more progressive jpg changes
...
- Remove the nocache stuff for prog jpg images. There was no saving in
practice, since operations downstream could be cached.
nocache is for objects that can change, not for memory saving
- Call _destroy on the decompress object much earlier, it frees a huge
amount of memoey for prog jpg images.

make test for matlab files more specific
...
Previously vips just called Mat_Open() to test if a file was a Matlab
save file, but this is rather unreliable. For example, some JPEG files
can crash libmatio, and it can incorrectly think that at least some JP2
files are Matlab save files.
Instead, look for "MATLAB 5.0" at the start of the file. This is really too
specific, the first 116 bytes of a Matlab save file are freeform text,
but in practice all Matlab writers use the first few bytes to record the
file type.
