Uploading large files may cause Gitea to crash on OOM. This load the image-header first and checks the sizes before proceeding.

(e.g. a 64250x64250 image becomes 4.1 Gigapixels. Which would allocate 16GB of RAM in RGBA8888.)

Since this can be used for DoS-attacks we should backport it. Just don't know which version yet 馃檪
