f6281284a1 fix VipsSource and named pipes 
We used to assume (in several places) that any source with a filename was
seekable. This patch adds a is_file test, and makes all the loaders use it.

f8c2a36746 arrayjoin signalling minimise also frees memory 
By making the sequential line cache non-persistent, and only minimising
when the read point is well past the image.

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

See https://github.com/kleisauke/net-vips/issues/135

a20cd4cdc1 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.

03f76b73b4 add "premultiply" param to tiffsave 
Some programs, like indesign, only work with premultiplied alpha in TIFF. To
make TIFFs which are compatible with these programs, we'll need an extra
TIFF save flag (perhaps premultiply?) to premultiply alpha and save as
EXTRASAMPLE_ASSOCALPHA.

d8ed630d77 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.
