We know that we want to put something into _notrans, no point in
doing another round trip into gencache.tdb.

gencache_notrans.tdb is much cheaper to look at than gencache.tdb because it's
mutexed and thus avoids expensive fcntl locks. This patch aggressively uses the
shared _notrans tdb for both positive and negative entries. It's a replacement
for the memcache copy in every process that was removed a few patches ago.

gencache_pull_timeout used to point at the "/" right after the timeout. None
of the callers was interested in the "/", they are interested in the payload.
Increment the endpointer in gencache_pull_timeout and rename it.

At this point we're still looking at TDB_DATA. This patch moves the casts to a

The main reason for this was to avoid access to the fcntl-governed transaction
based gencache.tdb. A later patch will make this unnecessary by filling
gencache_notrans more aggressively.

"net cache flush" can give nasty error messages like
Couldn't delete entry! key = IDMAP/UID2SID/12345
These happen when there's an already deleted entry in
gencache_notrans.tdb, indicated by a 0 timeout. This happens if two
gencache_del function calls have happened right after the other and a
gencache_stabilize has not wiped them.
In gencache_iterate, don't show these deleted entries

This uses time functions from lib/util/ which requires pulling in
samba-util. This sucks, but there's just no way of rewrapping a minimal
time utility library without modifying the public samba-util.

Implement this by explicitly checking for decimal or hexadecimal input.
This avoids using sscanf with %i and a signed integer type, and it also
matches the code paths for flags and mask that also have an explicit
check.

When determining the block device of our file system, avoid
stat'ing paths which are definitely not the mount point of
our file system. This is done to avoid stalling smbd due to
unresponsive network file systems (e.g. NFS) which are not
related to the SMB shares.

New syntax for interfaces parameter:
interfaces = address[;key=value[,key=value[,...]]]
- keys can be 'speed', 'capability', and 'if_index'.
- speed is in bits per second.
- capability can be RSS and RDMA.
- if_index should be used with care, because
these indexes should not conicide with indexes
