lock around accesses to uidinfo and varsymset

- add ->vx_lock to protect the varsymset fields
- add ->ui_lock to protect the rest of the fields in uidinfo
- protect the uidinfo hash
- the varsym*() syscalls are now mpsafe

This is obviously performance-irrelevant, but it allows
access to uidinfo without the BGL.
