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.

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

This app demonstrate usage of new rte_jobstats library.
It is basically the orginal l2fwd with following modifications to met
library requirements:
- main_loop() was split into two jobs: forward job and flush job. Logic
for those jobs is almost the same as in original application.
- stats is moved to rte_alarm callback to not introduce overhead of
printing.
- stats are expanded to show rte_jobstats statistics.
- added new parameter '-l' to automatic thousands separator.
Comparing original l2fwd and l2fwd-jobstats apps will show approach what
is needed to properly write own application with rte_jobstats
measurements.
New available statistics:
- Total and % of fwd and flush execution time
- management time - overhead of rte_timer + overhead of rte_jobstats
library
- Idle time and % of time spent waiting for fwd or flush to be ready to
execute.
- per job execution time and period.
