Fix gif dispose handling for DISPOSE_BACKGROUND and DISPOSE_PREVIOUS
- Add 'scratch' field to gif that holds temporary 'scratch buffer' used for rendering frames
- For DISPOSE_BACKGROUND: Set background color to transparent instead of 0
- For DISPOSE_BACKGROUND: Write background pixels into scratch after rendering current frame, so it will be used in next frame
- For DISPOSE_PREVIOUS: Save frames that are not disposed into 'previous' field in gif, when DISPOSE_PREVIOUS is specified start with that previous frame. see http://webreference.com/content/studio/disposal.html
- Add "ANIMEXTS1.0" to Application Extension parser
- Graphic Control Extension parser refactor
- Compare file contents to expected images for animated gifs in foreign tests

John Cupitt cf5cad2b3e make pipe read limit configurable
We had a 1gb limit on the amount of data we would read from a pipe
before giving up.

This patch adds vips_pipe_read_limit_set() and makes this limit
configurable.

John Cupitt 559ae542ac revise flags for vipsthumbnail
The --rotate flag no longer did anything, so add a new --no-rotate flag
connected to the new no-rotate property. --rotate is still there, but
hidden and does nothing.

-o was much easier to remember than -f, so flip back to -o. -f still
works, but is a hidden synonym.

--iprofile, --eprofile were hard to remember. Add --import-profile and
--export-profile synonyms. iprofile / eprofile are still there and still
work, but are hidden.

John Cupitt 8a21f6ea52 fix gif rendering for "waterfall.gif"
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.

John Cupitt e4db74746a fix a deadlock with --vips-leak
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.

John Cupitt 42930e8d87 add "depth" param to tiffsave

"depth" param on dzsave.

John Cupitt f8c7f9dac9 interpret \ as an escape char in break_token
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.

John Cupitt fda5e5c402 lock for metadata changes
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.

To make our meaning clearer.

libtiff uses uint64 for toff_t, with -1 cast to uint64 for an error
indication, see:
