Added a check to see if address space is valid in
addrSpaces map before accessing it. Also fixed some
error strings so that it provides better information
to the user.

Currently endpoint count is maintained as part of
network object and the endpoint count gets updated
frequently while the rest of network is quite stable.
Because of the frequent updates to endpoint count the
network object is getting marshalled and unmarshalled
ferquently. This is causing a lot of churn and transient
memory usage. Fix this by creating a deparate object of
endpoint count so that only that gets updated.

Currently there are 3 distinct operations performed by
datastore
- Pushing the data to the store
- Updating the Index of the local object
- Updating the cache (in case of localscope)
Without a lock racing datastore api calls can interleave
in various surprising ways. Best thing is to keep these
3 above operation inseparable. Use a datastore lock to
achieve this.

currently ipamutils package uses apis which are linux
specific and makes windows compile error out. Separated
the OS specific apis into linux and windows files to
diverge the implementation.

Today we try to increment/decrement endpoint count
only once even if it is a key modified error. In case
of key modified error we should retry it to allow it to
succeed.

- Both an empty and nil list of IpamConf object
will trigger auto-allocation for ipv4.
Auto-allocation for ipv6 will still be excluded
in the two cases above.

Currently when container has a restart policy and gets
restarted, docker does not release networking and allocate
it back. But it presents libnetwork with a new sandbox while
all the network resources are locked in the old sandbox. This
commit attempts to move all the network resources from the old
sandbox to the new sandbox when libnetwork is presented with the
new sandbox.

Currently integration test is a bit flaky because of
variability in the dnet bootup time. Fixed it to wait for
dnet to come up before performing any tests.

Added restart test for default network so that we can test
bridge network persistence. Also added changes to dnet to
delete the default network if it is present.
