Robert Watson 9080ff25cf Rename VOP_RMEXTATTR() to VOP_DELETEEXTATTR() for consistency with the 
kernel ACL interfaces and system call names.

Break out UFS2 and FFS extattr delete and list vnode operations from
setextattr and getextattr to deleteextattr and listextattr, which
cleans up the implementations, and makes the results more readable,
and makes the APIs more clear.

# Above each of the vop descriptors is a specification of the locking
# protocol used by each vop call. The first column is the name of
# the variable, the remaining three columns are in, out and error
# respectively. The "in" column defines the lock state on input,
# the "out" column defines the state on succesful return, and the
# "error" column defines the locking state on error exit.
#
# The locking value can take the following values:
# L: locked; not converted to type of lock.
# A: any lock type.
# S: locked with shared lock.
# E: locked with exclusive lock for this process.
# O: locked with exclusive lock for other process.
# U: unlocked.
# -: not applicable. vnode does not yet (or no longer) exists.
# =: the same on input and output, may be either L or U.
# X: locked if not nil.
#
# The paramater named "vpp" is assumed to be always used with double
# indirection (**vpp) and that name is hard-codeed in vnode_if.awk !
#
# If other such parameters are introduced, they have to be added to
# the AWK script at the head of the definition of "add_debug_code()".
