GetLastError()

861f6d1ef4 radload was not setting priority correctly 
We used to have separate subclasses for file, buffer and stream load,
but only set ->priority in one of them.

Rework radload as a base class plus a set of implementations.

0429a0080e swap ssize_t for gint64 where possible 
Some versions of the Windows headers define ssize_t as unsigned. This
patch removes (where possible) use of ssize_t inside libvips, esp. in
the new stream API.

e48f45187b make RGB and sRGB synonmous 
We had a half-baked idea that RGB could mean generic RGB space and sRGB
would mean strict sRGB interpretation.

Unfortunately, this did not work well in practice. For example,
`icc_transform("srgb")` would tag the result as RGB rather than sRGB
(the converter didn't know it was writing sRGB pixels, it just saw
conversion to RGB with an ICC profile), and then later stages would do
unnecessary icc_imports, or worse, fail.

This patch makes RGB and sRGB strict synonyms. If you want to treat an
RGB image as something other than sRGB, you'll need to do it by hand
with the icc_ functions.

fix: do not try to use "undefined" delay 
Expression could be truthy even when no `delay` was provided by user.

Now, the `delay_length` is 0 by default to avoid this situation.

8f95b08218 put seq access back in to tilecache

simplification, but it turns out it's needed for vips_sequential().

1fd3b478e1 always check memory area length 
vips_image_new_from_memory() allowed you to use length == 0 to mean
"don't check memory length". This was part of some very old vips7
compatibility.

The ppm loader could pass length == 0 if header size was equal to file
size, bypassing the length check.

e236f19f97 add fallbacks to new_from_stream 
If the stream-based loaders fail, vips_image_new_from_stream() now falls
back to the old file and buffer loaders.

The file and buffer loaders already try the stream loaders first.
