Message:

VFS work.
Upon FS registration via VFS_REGISTER, the client is assigned a unique file
system handle. When generating the VFS_LOOKUP request in VFS, we also need to
pass the device handle. Add function to transform file system handle to phone.
Implement basic multi-call VFS request serialization on VFS side.
