caed71af04 emit "finish" at the end of targetcustom write 
In 8.13 we deprecated target_finish() (it did not have an error return)
to target_end() (now has an error return).

This PR makes target_end() also emit the "finish" signal for
compatibility with the previous API. ruby-vips, for example, looks for
on_finish() to close files.

See https://github.com/libvips/ruby-vips/issues/351

Thanks lucaskanashiro

* spngsave: ensure quantisation occurs last

i.e. after setting the metadata and phyiscal pixel dimensions,
since quantisation will overwrite the image.

* spngsave: avoid over-allocation of temporary buffer

For low-bitdepth write and palette-based output.

29e80ca43f better 0 detection in unpremultiply 
We were avoiding /0 by testing for alpha==0, however, this will still
allow very small values of alpha to generate +/- Inf. Instead, check for
abs(alpha)<epsilon.

Fixes some artifacts after unpremul.

2c4c039056 add "unlimited" to jpegload 
To disable DoS limits for JPEG loading. Adding API on a stable branch is
bad, but this fixes a regression, so I think it's necessary,
unfortunately.

Remove unneeded adapter function for Emscripten (#2949)

wasm-vips to include the missing `class_data` member, so this adapter

Update glib-mkenums templates (#2939) 
* Avoid writing the full path in enumtypes.h

Helps reproducible builds, as build paths can vary between builds.

* Use g_intern_static_string() for enum/flags type names

We are emitting a static string, so use that shortcut function to
intern it, which will save one allocation.

* Use g_once_init_enter/leave to register enum/flags type names

This is the more modern way, and ensures thread-safety.
