Add an extra parameter to the ring dequeue burst/bulk functions so that
those functions can optionally return the amount of remaining objs in the
ring. This information can be used by applications in a number of ways,
for instance, with single-consumer queues, it provides a max
dequeue size which is guaranteed to work.

Add an extra parameter to the ring enqueue burst/bulk functions so that

for instance, with single-producer queues, it provides a max

implement watermark functionality in apps, replacing the older
functionality with a more flexible version, which enables apps to
implement multiple watermark thresholds, rather than just one.

Before this patch, the management of dependencies between directories
had several issues:
- the generation of .depdirs, done at configuration is slow: it can take
more than one minute on some slow targets (usually ~10s on a standard
PC without -j).
- for instance, it is possible to express a dependency like:
- app/foo depends on lib/librte_foo
- and lib/librte_foo depends on app/bar
But this won't work because the directories are traversed with a
depth-first algorithm, so we have to choose between doing 'app' before
or after 'lib'.
- the script depdirs-rule.sh is too complex.
- we cannot use "make -d" for debug, because the output of make is used for
the generation of .depdirs.
This patch moves the DEPDIRS-* variables in the upper Makefile, making
the dependencies much easier to calculate. A DEPDIRS variable is still
used to process library dependencies in LDLIBS.
After this commit, "make config" is almost immediate.

Fixes the buffer overflow that occurs due to following;
1. When the input packet burst does not meet the conditions: (a) being
contiguous (first n bits set in pkts_mask, all the other bits cleared)
and (b) containing a full burst, i.e. at least tx_burst_sz packets
(n >= tx_burst_size). This is the slow(er) code path taken when local
variable expr != 0.
2. There are some packets already in the buffer.
3. The number of packets in the incoming burst (i.e. popcount(pkts_mask))
plus the number of packets already in the buffer exceeds the buffer size
(RTE_PORT_IN_BURST_SIZE_MAX, i.e. 64).

Originally, sink ports in librte_port releases received mbufs back to
mempool. This patch adds optional packet dumping to PCAP feature in sink
port: the packets will be dumped to user defined PCAP file for storage or
debugging. The user may also choose the sink port's activity: either it
continuously dump the packets to the file, or stops at certain dumping
This feature shares same CONFIG_RTE_PORT_PCAP compiler option as source
port PCAP file support feature. Users can enable or disable this feature
by setting CONFIG_RTE_PORT_PCAP compiler option "y" or "n".

Originally, source ports in librte_port is an input port used as packet
generator. Similar to Linux kernel /dev/zero character device, it
generates null packets. This patch adds optional PCAP file support to
source port: instead of sending NULL packets, the source port generates
packets copied from a PCAP file. To increase the performance, the packets
in the file are loaded to memory initially, and copied to mbufs in circular
manner. Users can enable or disable this feature by setting
CONFIG_RTE_PORT_PCAP compiler option "y" or "n".
