This GIF has dispose set to DISPOSAL_UNSPECIFIED and seems to mean
transparent.
This patch makes gifload use DISPOSAL_UNSPECIFIED as well as _DO_NOT to
mean reuse previous frame.
Thanks DarthSim.

We were usingh a global lock for metadata changes, but some functions
triggered from callbacks in the metadata hash table could also attempt
to acquire the same mutex, leading to deadlock.
This patch gives metadata change it's own lock. Thanks DarthSim.

So:
vips_break_token( "hello\ world", " " )
Sees a single token, `"hello world"`.
This means you can now do things like:
$ vips arrayjoin "k\ 2.jpg" x.png
Where "k 2.jpg" is a filename containing a space.

Another attempt at fixing crashes on metadata chenage in highly threaded
applications.
Global lock around set, remove and copy metadata. This is crude, but
simple, the performance impact should be small, and ought to resolve the
problem.
We'll do something better for the next version.

We weer minimising sources in the ::minimise handler, but this is called
outside the lock that protects _generate. This patch removes minimise in
this case.

We were attempting to load images in new_from_file using the new source
API first, then only falling back to the file loaders if that failed.
However, this meant that we did not respect the priority ordering on
loaders, so openslide iamges (for example) were being loaded by the tiff
loader.
We were always setting page-height in thumbnail, even on single-frame
images. This could cause problems if the image height was later
increased by a factor of the height -- non-animated images could
accidentally turn into animated images.

We declared vips_mapimage() in histogram.h. This became
vips_case() later in development, but this old decl was left behind in
error.
Thanks @remicollet

Free the shrinkv line buffer and struct at the end of eval, not on image
dispose. This helps keep mem use down in some long-running operations.
Thank you homm, see https://github.com/libvips/pyvips/issues/147
