285f6c7418 add casts for tiff seek 
To make our meaning clearer.

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

https://gitlab.com/libtiff/libtiff/blob/master/libtiff/tif_unix.c#L123

8c1c8b6c9f fix a warning from magicksave on some platforms 
we were leaving delay_gvalue as {0} then unsetting it, which will
produce a warning with some versions of glib.

Thanks chregu.

51fc2ff64e don't use new source API for new_from_file etc. 
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.

5b09845bd5 don't set page-height in thumbnail unless we must 
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.

0cdf00a9ba remove stray declaration of vips_mapimage() 
We declared vips_mapimage() in histogram.h. This became
vips_case() later in development, but this old decl was left behind in
error.

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.
