Type: improvement
Remove rwlock contention on timestamps. ~10% pps with
10k sessions. Use fixed-size-pools of increasing sizes
starting with 4K, and with a x2 step each time.
We don't free/shrink allocated pools.

In a case where one pounds on a single kvp in a KVP_AT_BUCKET_LEVEL
table, the code would sporadically return a transitional value (junk)
from a half-deleted kvp. At most, 64-bits worth of the kvp will be
written atomically, so using memset(...) to smear 0xFF's across a kvp
to free it left a lot to be desired.
Performance impact: very mild positive, thanks to FC for doing a
multi-thread host stack perf/scale test.
Added an ASSERT to catch attempts to add a (key,value) pair which
contains the magic "free kvp" value.

When dNAT-ing to a VIP, it can happen
that the return session conflicts with
another forward session than the one
we own.
This patchs adds a rsession_flags
CNAT_SESSION_RETRY_SNAT that makes cnat_session_create
search for a free src port to use for the
resulting return session.
It also makes forward & return session
share their fate in the session scanner.
