ethdev: add traffic manager query

Add function to allow querying a node in the scheduler tree. Returns
the parameters as were given to the add function. Adding this function
allows apps to just query the hierarchy rather than having to maintain
their own copies of it internally.

It is used in testpmd to print out details about previously added TM nodes.
Example output, configuring three nodes, and then printing the details:

testpmd> add port tm nonleaf node 0 100 -1 0 1 0 -1 1 0 0
testpmd> add port tm nonleaf node 0 90 100 0 1 1 -1 1 0 0
testpmd> add port tm leaf node 0 0 90 0 1 2 -1 0 0xffffffff 0 0

ethdev: make TM shaper parameters constant

The function to add a new shaper profile in rte_tm should not (and does
not) modify the profile parameters passed in via struct pointer. We
should guarantee this by marking the parameter pointer as const. This
allows SW to create multiple profiles using the same parameter
struct without having to reset it each time.

lib: remove librte_ prefix from directory names

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
