Modify the ipfix_exporter to use ip_address instead of the ipv4 specific
version. Modify the current code so that it writes into the v4 specific
part of the address, i.e. we are not yet fully supporting IPv6. For the
exporter configured via the original API (the one that is always in slot0)
we will not support IPv6 addresses.

When a new flow-report is created the caller provides 2 callback functions.
These functions both take a pointer to the exporter, plus a pointer to the
source and dest address. However the pointers to the address are not adding
any value as these are always set to the src/dest addresses of the exporter
(which is already being passed). Remove these parameters and leave the
callback functions to get the addresses out of the exporter.

The ipfix exporter should be doing most of the work of building packets
and sending them rather than leaving every client of the exporter to do
all the work themselves. Start to move towards that by adding APIs to
get and send buffers. Store the state of this in new per thread data on
the report so that we can send with minimal use of atomics. We do need
an atomic for the sequence number in the packet though as that contains
the number of data_records sent for the 'stream', not just for a single
core. As the state is stored on the flow_report_t the caller needs to
know which report they are using, so add a field to the args struct used
to create the report that is used to pass back the report index on success.

The existing api set_ipfix_exporter only allows for the creation of
a single exporter. In some cases it is desirable to export data to
multiple different destinations. Allow users to create multiple
ipfix exporters to support this.
Add a new api that allows for the creation of multiple exporters, and
store them in a pool of exporters. The exporter created by the old API
will always be in index 0 of the pool. Exporters created by the new API
will be given the next available index in the pool, and will return this
index to the API caller so that they can track the exporter they created.
The collector_address is the key for the exporter, so changes can be made
by doing a further call to the API with the same collector_address.

Pass an ipfix_exporter to this function so that callers can choose which
exporter they are modifying.

Pull out the fields in flow_report_main_t that are specific to a single
exporter and move them into a new structure that represents an exporter.
Add a pool of exporters to flow_report_main_t and do a pool_get() to get
the entry at index 0, so that the existing users of the code need only
change the path at which they access the old fields and have no need to
make further code changes. In functions that were accessing the fields
that now make up the ipfix_exporter create a local var that points to the
first (always valid) exporter and use this as the base for the fields
rather than finding them from flow_report_main.
This is in preparation for supporting multiple flow_exporters.
Note that at the moment the code supports multiple 'streams' for a given
exporter, where each stream has its own source port, domain id and template
space. But all streams within an exporter have the same destination address,
so this is not the same as multiple exporters.

Instead of repeatedly cutting, pasting, and hacking to create a new
callback, use vnet_flow_rewrite_generic_callback(). Add three
arguments to the flow rewrite callback:
(in) pointer to an array of report elements,
(in) length of array,
(out) pointer to the stream index
Change existing code prototypes. Code owners encouraged to evaluate
whether they can use the generic callback or not, at leisure.
