Latest mbuf changes (priv_size addition and related fixes)
exposed small problem with testpmd and few other sample apps:
when mbuf size is exaclty 2KB or less, that causes
ixgbe PMD to select scattered RX even for configs with 'normal'
max packet length (max_rx_pkt_len == ETHER_MAX_LEN).
To overcome that problem and unify the code, new macro was created
to represent recommended minimal buffer length for mbuf.
When appropriate, samples are updated to use that macro.
Fixes: dfb03bbe2b ("app/testpmd: use standard functions to initialize
mbufs and mbuf pool")

When it's possible, use the new helper to create the mbuf pools.
Most of the patch is trivial, except for the following files that
have some specifics (indirect mbufs):
- ip_fragmentation
- ip_pipeline
- ipv4_multicast
- vhost

There was no error checking after calling rte_reorder_create.
Move the creation of the reorder buffer before launching threads
in case of memory error.

This new app makes use of the librte_reorder library.
It requires at least 3 lcores for RX, Workers (1 or more) and TX threads.
Communication between RX-Workers and Workers-TX is done by using rings.
The flow of mbufs is the following:
* RX thread gets mbufs from driver, set sequence number and enqueue
them in ring.
* Workers dequeue mbufs from ring, do some 'work' and enqueue mbufs in
ring.
* TX dequeue mbufs from ring, inserts them in reorder buffer, drains
mbufs from reorder and sends them to the driver.
