User-agent: Wanderlust/2.15.9 (Almost Unreal) SEMI-EPG/1.14.7 (Harue) FLIM-LB/1.14.9 (Gojō) APEL-LB/10.8 EasyPG/1.0.0 Emacs/27.2 (x86_64-apple-darwin18.7.0) MULE/6.0 (HANACHIRUSATO)

shr.el has already a blacklist feature via `shr-blocked-images'
variable. However in the setting of using shr as an email pager to
display HTML contents, it is much more useful to have a "whitelist"
feature.

Summary of changes:

Added variable `shr-safe-images', nil means all images are
allowed. This can be overriden by setting existed `shr-blocked-images'.

Added subst function `shr-image-is-blocked'.
