Many codecs can take a huge amount of time attempting to read large
random objects. jpeg_read_header(), for example, can take ~10s on a 1mb
of random data.

Ignore fuzz objects over 100kb.

try to work around some broken heic images

new_from_memory_steal() will create a new image with the input
buffer and will "move" the data into the image. The buffer is then
managed by the image, and will be freed when it goes out of scope.

Some old gccs (eg. centos6) throw errors for this.

doxy hates #include inside classes

Prevents a zero-length buffer from crashing GetImageMagick

It looks like the fix for magick7 in libvips#1642 is also now required
for magick6 as the assertion appears to have been backported.

Ensure magick buffer+file checks use consistent min length guard

webpload: ensure first frame is not blended

see libvips#1918

fixes libvips#1901

Fix two bugs:

- clip in casts from int32 and uint32 could overflow -- do these as gint64 now

- clip in casts from float to int could overflow since float32 can't
  represent the full range of int32 without losing precision -- do these
  as double

And add some more tests.

Thanks ewelot.
