This adds new functions that will be called
through unix-socket and permit to update
and show memcap value.
The memcap value needs to be handled in a
thread safe way, so for this reason it is
declared as atomic var.
Another function is added to gets
the memuse value since it will be shown
through unix-socket.

Fix minor compiler warnings for these new flags on gcc and clang.
Tilera's GCC supports the GCC __sync_ intrinsics.
Increase the size of some atomic variables for better performance on
Tile. The Tile-Gx architecture has native support for 32-bit and
64-bit atomic operations, but not 8-bit and 16-bit, which are emulated
using 32-bit atomics, so changing some 16-bit and 8-bit atomic into
ints improves performance.
Increasing the size of the atomic variables modified in this change
does not increase the total size of the structures in which they
reside because of existing padding requirements. The one case that
would increase the size of the structure (Flow_) was confitionalized
to only change the size on Tile.
This patch should fix the bug #637. Between pcap files, it uses a
new function HostCleanup() to clear tag and threshold on host with
an IP regputation. An other consequence of this modification is
that Host init and shutdown are now init and shutdown unconditionaly.
Add a host table similar to the flow table. A hash using fine grained
locking. Flow manager for now takes care of book keeping / garbage
collecting.
Tag subsystem now uses this for host based tagging instead of the
global tag hash table. Because the latter used a global lock and the
new code uses very fine grained locking this patch should improve
scalability.
