Support the whole 128 feature's bits in library.

Support the whole 128 feature's bits in library.

It will be useful to load libraries for preload features,
because they are on the last 64 bits of features now.
Also, features are passed as integers, not as string as before.

This commit is related with swap-manager commit of the same
name.
