VFS: swap do_ioctl and vfs_ioctl names
Rename old vfs_ioctl to do_ioctl, because the comment above it clearly
indicates that it is an internal function not to be exported to modules;
therefore it should have a more traditional do_XXX name. The new do_ioctl
is exported in fs.h but not to modules.
Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should
preferably be reserved to callable VFS functions which modules may call, as
many other vfs_XXX functions already do. Export the new vfs_ioctl to GPL
modules so others can use it (including Unionfs and eCryptfs). Add DocBook
for new vfs_ioctl.
