We're adding enough nfs documentation that it may as well have its own
subdirectory.

Update documentation to the current state of affairs. Remove duplicated
method descruptions in exportfs.h and point to Documentation/filesystems/
Exporting instead. Add a little file header comment in expfs.c describing
what's going on and mentioning Neils and my copyright [1].

Create "export_operations" interface for filesystems to describe
whether and how they should be exported.
- add new field in struct super_block "s_export_op" to describe
how a filesystem is exported (i.e. how filehandles are mapped to
dentries).
- New module: fs/exportfs for holding helper code for mapping between
filehandles and dentries
- Change nfsd to use new interface if it exists.
- Change ext2 to provide new interface
- Add documention to filesystems/Exporting
If s_export_op isn't set, old mechanism still works, but it is
planned to remove old method and only use s_export_op.

nfsd to use.
Prepare for new export_operations interface (for filehandle lookup):
- define d_splice_alias and d_alloc_anon.
- define shrink_dcache_anon for removing anonymous dentries
- modify d_move to work with anonymous dentries (IS_ROOT dentries)
- modify d_find_alias to avoid anonymous dentries where possible
as d_splice_alias and d_alloc_anon use this
- put in place infrastructure for s_anon allocation and cleaning
- replace a piece of code that is in nfsfh, reiserfs and fat
with a call to d_alloc_anon
- Rename DCACHE_NFSD_DISCONNECTED to DCACHE_DISCONNECTED
- Add documentation at Documentation/filesystems/Exporting
