This commit renames all secure_media related settings to secure_uploads_* along with the associated functionality. This is being done because "media" does not really cover it, we aren't just doing this for images and videos etc. but for all uploads in the site. Additionally, in future we want to secure more types of uploads, and enable a kind of "mixed mode" where some uploads are secure and some are not, so keeping media in the name is just confusing. This also keeps compatibility with the `secure-media-uploads` path, and changes new secure URLs to be `secure-uploads`. Deprecated settings: * secure_media -> secure_uploads * secure_media_allow_embed_images_in_emails -> secure_uploads_allow_embed_images_in_emails * secure_media_max_email_embed_image_size_kb -> secure_uploads_max_email_embed_image_size_kb

# There are certain conditions with secure uploads when the security of
|
|
# uploads will need to change depending on the context they reside in.
|
|
#
|
|
# For example on these conditions:
|
|
# * Topic category change
|
|
# * Topic switching between PM and public topic
|
|
# * Post moving between topics
|
|
#
|
|
# We need to go through all of the posts in that topic that
|
|
# own uploads via access_control_post_id, then for those uploads determine
|
|
# if they still need to be secure or not. For example an upload could be
|
|
# secure if it is in a PM, and then when the topic gets converted to a public
|
|
# topic the upload no longer needs to remain secure as it is no longer in
|
|
# a secure context.
