* Path globbing
* Add glob support at the beginning
* Ensure when evaluating an ACL that our path never has a leading slash. This already happens in the normal request path but not in tests; putting it here provides it for tests and extra safety in case the request path changes
* Simplify the algorithm, we don't really need to validate the prefix first as glob won't apply if it doesn't
* Add path segment wildcarding
* Disable path globbing for now
* Remove now-unneeded test
* Remove commented out globbing bits
* Remove more holdover glob bits
* Rename k var to something more clear
This commit splits ACL policies into more fine-grained capabilities.
This both drastically simplifies the checking code and makes it possible
to support needed workflows that are not possible with the previous
method. It is backwards compatible; policies containing a "policy"
string are simply converted to a set of capabilities matching previous
behavior.
Fixes#724 (and others).
