John Cupitt 348e5e1523 don't set JFIF res if we will set EXIF res
Some JPEG loaders give priority to JFIF resolution over EXIF resolution
tags. This patch makes libvips not write the JFIF res tags if it will be
writing the EXIF res tags.

John Cupitt 801111a2fa better dint rules

predictable.

Lovell Fuller b73bc3a855 Ensure magick buffer+file checks use consistent min length guard
Prevents a zero-length buffer from crashing GetImageMagick

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

John Cupitt cb1634dd31 block fuzz data over 100kb
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.
