sizealike() and friends elide completely
...
sizealike() / formatalike() and bandsalike() used to just vips_copy() if
the image didn't need any changes ... this was fast, but left a
vips_copy_gen() in the pipeline, wasting a lot of space on the C stack
during recursion.
They now vanish completely if the image is already in the right format.
Since we call them before most image processing operations, and
often all three of them, this saves a lot of C stack, more than x2 even
in simple cases.
There might also be a measureable CPU saving if the operations are very
simple (eg. insert).

better alpha handling for tiff save
...
the tiff saver was writing all five-band images as CMYKA, even if they
were tagged as srgb ... it now follows the interpretation tag and will
write many alpha channels instead

return default value for unset props
...
we used to issue a warning and return early, but this can leave garbage
in the *value pointer, I think
ruby gobject-introspection will walk object props during GC and can see
state inbetween init and build when not all objects have been given a
value ... we don't want these warnings

change exif names argh

change exif names again: we were storing under @title, but that's both
subject to i18n, and unlookupable in libexif
we now use @name, which is not subject to i18n and can be searched for
... this will break most code which expects certain exif tag names
also, when we update exif, allow any tag, not just updates to existing
tags, see:
