090ae07bc2 [vold] Check incremental paths before mounting 
Vold was trusting system_server too much and allowed for pretty
much any path in mount()/bindMount() calls for incremental.
This CL adds validation to make sure it's only accessing own
directories. This includes enforcing no symlinks in the paths

Ignore-AOSP-First: security fix

605a44fe93 Additional operation check when enabling read logs. 
Vold now does not check caller's permission, but only accepts
transactions from system_server. And it's up to system server to do the
right thing and check permissions/appops.
