Subject: make alloc_anon_inode more useful

Hi all,

this series first renames the existing alloc_anon_inode to
alloc_anon_inode_sb to clearly mark it as requiring a superblock.

It then adds a new alloc_anon_inode that works on the anon_inode
file system super block, thus removing tons of boilerplate code.

The few remainig callers of alloc_anon_inode_sb all use alloc_file_pseudo
later, but might also be ripe for some cleanup.
