Add very basic support for the kernel to export a list of features. Each
feature is represented by a node in the new 'kern.features' sysctl node.
A feature is present if the corresponding node is present and evaluates to
true.
A FEATURE() wrapper macro is added which takes the sysctl node name and
a description of the feature as the sole arguments and creates a read-only
sysctl node with a value of 1.
