Cleanup gettext handling (#2695)
Use GLib's i18n support instead of copying and pasting that
logic into its own header. This deprecates the vips/intl.h
header in favour of glib/gi18n.h.

Fix flatten clip (#2432)
* fic gtk-doc typenames in cgif

* fix flatten clipping

flatten could produce out of range values if max_alpha was less than
the limit of the numeric range of the format

Fix UBSan errors (#1948)
* Ensure UBSan exits with a non-zero code on error

* Avoid misaligned member access in mosaic_fuzzer

* Add missing VIPS_CLIP in scRGB2sRGB/scRGB2BW

* Fix UBSan error in flatten

By using saturated casts for the int types (copied from vips_cast).

* CI: ensure fuzzer log is printed on error

* Avoid UB in heifload

* Revert flatten change

I could no longer reproduce this with clang 12 locally.

* Indentation fixes [skip ci]

John Cupitt dbbd2850a1 better max_alpha default
it used to default to 255, now it sniff the interpretation and defaults to
65535 for RGB16 and GREY16

John Cupitt 07a1903390 use g_assert_not_reached()
we were using g_assert(0) ... g_assert_not_reached() makes the
intention clearer

John Cupitt 12cf71a6a9 combin copy_fields and demand_hint
We had two API calls, vips_image_copy_fields() and vips_demand_hint().
They are now combined in the single vips_image_pipeline() call.

All operations are now slightly smaller and simpler.

things like

	vips copy huge.png x.v

now run with only a small line cache

John Cupitt 643dc28950 turn on seq mode automatically in cli
cli operations turn on seq mode automatically when they can

vips_operation_get_flags() added: lets you attach a set of flags to an
operation

flags for now are "nocache" (replacing the old nocache system) and "seqential"

if vips_object_set_argument_from_string() from string sees "seq" flag on the
object for which it is setting the arg, it enables sequential mode

all operations which can run sequentially have been tagged

the operation printer knows about flags and can display them
