exports: add a configurable time-to-live for the kernel cache entries
From: Trond Myklebust <Trond.Myklebust@netapp.com>
The fedfs ldap server will specify a ttl for its entries.
Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
This is a refactoring change only. There should be no change in
behavior.
Original patch had updates to utils/mountd/junctions.c, which no
longer exists. These are not included here.
Create a macro for the default cache TTL, which is used in several
places besides the export cache.
Make e_ttl unsigned.
