cbc12b0a96 mk: do not generate LDLIBS from directory dependencies
The list of libraries in LDLIBS was generated from the DEPDIRS-xyz
variable. This is valid when the subdirectory name match the library
name, but it's not always the case, especially for PMDs.

The patches removes this feature and explicitly adds the proper
libraries in LDLIBS.

Some DEPDIRS-xyz variables become useless, remove them.

db0dc9b32a power: add send channel msg function to map file
Adding new wrapper function to existing private (but unused 'till now)
function with an rte_power_ prefix.

The plan is to clean up all the header files in the next release so
that only the intended public functions are in the map file and only
the relevant headers have the rte_ prefix so that only they are
included in the documentation.

feb9f680cd mk: optimize directory dependencies
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.

f87a9ddc4a power: fix error messages
Function strerror(errno) has built strings only for non-negative errno values.
for negative values of errno it describe error as "Unknown error -errno"
to be more descriptive i put string "channel not found" taken from header.

The negative argument will be interpreted as a very large unsigned value.

133b75923b mk: add library version extension
To differentiate libraries that break ABI, we add a library version number
suffix to the library, which must be incremented when a given libraries ABI is
broken.  This patch enforces that addition, sets the initial abi soname
extension to 1 for each library and creates a symlink to the base SONAME so that
the test applications will link properly.

445c6528b5 power: common interface for guest and host
Moved the current librte_power implementation to rte_power_acpi_cpufreq, with
renaming of functions only.
Added rte_power_kvm_vm implementation to support Power Management from a VM.

librte_power now hides the implementation based on the environment used.
A new call rte_power_set_env() can explicidly set the environment, if not
called then auto-detection takes place.

rte_power_kvm_vm is subset of the librte_power APIs, the following is supported:
 rte_power_init(unsigned lcore_id)
 rte_power_exit(unsigned lcore_id)
 rte_power_freq_up(unsigned lcore_id)
 rte_power_freq_down(unsigned lcore_id)
 rte_power_freq_min(unsigned lcore_id)
 rte_power_freq_max(unsigned lcore_id)

The other unsupported APIs return -ENOTSUP

cd0d5547e8 power: vm communication channels in guest
Allows for the opening of Virtio-Serial devices on a VM, where a DPDK
application can send packets to the host based monitor. The packet formatted is
specified in channel_commands.h
Each device appears as a serial device in path
/dev/virtio-ports/virtio.serial.port.<agent_type>.<lcore_num> where each lcore
in a DPDK application has exclusive to a device/channel.
Each channel is opened in non-blocking mode, after a successful open a test
packet is send to the host to ensure the host side is monitoring.
