add minimise to insert
...
This patch makes "insert" issue minimise signals for inputs in sequential
mode. This can drop memory use in some programs, for example:
```python
import sys
import random
import pyvips
image = pyvips.Image.black(20000, 20000)
for filename in sys.argv[2:]:
tile = pyvips.Image.new_from_file(filename, access='sequential')
x = random.randint(0, image.width - tile.width)
y = random.randint(0, image.height - tile.height)
image = image.insert(tile, x, y)
image.write_to_file(sys.argv[1])
```
Before this patch:
```
$ for i in {0..1000}; do cp ~/pics/k2.jpg $i.jpg; done
$ /usr/bin/time -f %M:%e ../manyjoin.py ../x.jpg *.jpg
5456256:4.34
```
With this patch:
```
$ /usr/bin/time -f %M:%e ../manyjoin.py ../x.jpg *.jpg

tell buffer and target savers the file format ( #2499 )
...
tell buffer and target savers the file format
Currently, buffer and target savers are not told the format they should
write.
This is usually OK (the JPEG saver already knows it should write JPEG),
but some savers can write several formats, and these currently need an
extra parameter.
For example:
```ruby
buf = x.write_to_buffer ".bmp", format: "bmp"
```
The first ".bmp" gets libvips to pick magicksave, the second
`format:` param is necessary to tell magicksave to write BMP.
This patch adds stub subclasses so that the savers know the exact format. It also improves PPM save.

arrayjoin signalling minimise also frees memory
...
By making the sequential line cache non-persistent, and only minimising

On large arrayjoin operations, this saves many GB of memory.

minimise arrayjoin inputs during processing

arrayjoin with a sequential pipeline will now minimise inputs when they
are no longer being used. This drops the number of open file handles
needed to construct large arrays.
Sadly, memory savings are minimal.

We were not avoiding NaN in float transform images, leading to segvs in
some cases.

better 8/16 bit casting for pngsave
...
pngsave was just using the image format to decide whether to save as 8
or 16 bit PNG. With this patch it checks Type as well.
This means that eg. a uint32 image tagged as sRGB will save as png8, but
a uint32 image tagged as RGB16 will save as png16.

fix range clips for casts to and from int
...
Fix two bugs:
- clip in casts from int32 and uint32 could overflow -- do these as gint64 now
- clip in casts from float to int could overflow since float32 can't
represent the full range of int32 without losing precision -- do these
as double
And add some more tests.
Thanks ewelot.
