d_count is now an int protected by the dentry's d_lock.
Take the lock when we use it, instead of using an atomic_*

dcache_lock is gone in 2.6.38, and some of the vfs locking rules
have changed.
Of interest for openafs:
- inode->i_lock protects the d_alias list
- dentry->d_lock protects d_unhashed()
Add a new configure test for dcache_lock, and replace its use by
the appropriate new lock(s).

In 2.6.38, the super block structure has a new field to hold the
default dentry ops. The vfs will automatically set it for new
dentries in most cases.
Set s_d_op to our set of operations, and omit setting the dentry
ops where the vfs will already do it (and where new locking rules
prohibit it).

As part of changes to the truncate sequence, inode_setattr() no
longer exists, and all filesystems have to define the setattr op
so we can assume that it is not NULL.
Introduce a compat inline function afs_inode_setattr that hides
the tests and the different versions from the main code.
Note that the existing test for the inode_setattr() return type
will fail, but the value is no longer used in that case.
This is required for 2.6.36
