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

Since commit b1fb53a39d ("ethdev: remove some PCI specific handling"),
rte_eth_dev_info_get() relies on dev->data->drv_name to report the driver
name to caller.
Having the pmds set driver_info->driver_name in the pmds is useless,
since ethdev overwrites it right after.
The only thing the pmd must do is:
- for pci drivers, call rte_eth_copy_pci_info() which then sets
data->drv_name
- for vdev drivers, manually set data->drv_name
At this stage, virtio-user does not properly report a driver name (fixed in
next commit).

Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it. The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool. For example:
PMD_REGISTER_DRIVER(ena_driver, ena);
registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";
which pmdinfogen can search for and extract. The subsequent macro
DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);
creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";
Which allows pmdinfogen to find the pci table of this driver
Using this pattern, we can export arbitrary bits of information.
pmdinfo uses this information to extract hardware support from an object
file and create a json string to make hardware support info discoverable
later.

- it allows to disable link auto-negociation (single fixed speed).
- default: auto-negociate all supported speeds.
A flag autoneg in struct rte_eth_link indicates if link speed was a

The ring ethdev creation function creates an ethdev, but does not
actually set it up for use. Even if it's just a single ring, the user
still needs to create a mempool, call rte_eth_dev_configure, then call
rx and tx setup functions before the ethdev can be used.
This patch changes things so that the ethdev is fully set up after the
call to create the ethdev. The above-mentionned functions can still be
called - as will be the case, for instance, if the NIC is created via
commandline parameters - but they no longer are essential.
The function now also sets rte_errno appropriately on error, so the
caller can get a better indication of why a call may have failed.

The rte_eth_from_rings API allowed the creation of an ethdev port at
runtime using rte_rings as the underlying storage. However, the return
value from this function was either 0 or -1, and these values were never
actually documented in the API documentation. Unfortunately, the programmers
guide doc examples for this API implied that the return value from this
function was the port id of the newly created ethdev.
Since this latter behaviour is more useful - and already implied by the
documentation, this patch changes the return 0 to "return
data->port_id". It also adds in doxygen comments for the function so it
can be correctly documented in the API reference.
