add vips_target_end (#2802) 
since finish did not return an error code

also make sure we don't call target_end from inside _dispose, since that
can't signal error either

see https://github.com/libvips/libvips/issues/2801

Add a way to disable less well tested operations (#2636) 
* quick proposal

warn on startup if untrusted operations might run

use vips_block_untrusted_set() to block untrusted operations, set an env
var or make a file to stop the warning

* mark fits, nifti and svg as untrusted

* remove the annoying "untrusted" warning message

better to warn on the download page

leave vips_block_untrusted_set() since it's obviously useful

* separate UNTRUSTED and BLOCKED

* typos

* add VIPS_BLOCK_UNTRUSTED env var

* move BLOCK_UNTRUSTED after plugin load

obviously, ooops

* add a test, disable *magick

although *magick is fuzzed, it's probably safer to disable it in
untrusted environments

* mark some more operations as untrusted

e0bb8e5d58 make exif resunit optional and default to inch 
Some images don't set the exif resolution unit. We were ignoring exif
resolution in this case, but that's not correct, it's supposed to
default to inch.
