d67b8d7bd8 eal: allow empty compile time cpu flags
When RTE_COMPILE_TIME_CPUFLAGS is empty, the rte_cpu_check_supported()
code breaks with a "comparison is always false due to limited range of
data type".  This is because the compile_time_flags[] array is empty.
Assigning the array dimension to a local variable apparently solves this.

f7f500d245 app/test: restrict x86 cpu flags checks to x86 builds
The original code mistakenly defaulted to X86 when RTE_ARCH_PPC_64 was

05c69b4403 mk: fix shared lib build with stable abi
When next ABI is enabled, the shared lib extension is .so.x.1.
That's why a double basename was introduced.
But the "ifeq NEXT_ABI" was forgotten, removing the .so

It was preventing the linker from finding the .so libraries.

473d1bebce hash: allow to store data in hash table
Usually hash tables not only store keys, but also data associated
to them. In order to maintain the existing API, the old functions
will still return the index where the key was stored.
The new functions will return the data associated to that key.
In the case of the lookup_bulk function, it will return also
the number of entries found and a bitmask of which entries
were found.

Unit tests have been updated to use these new functions.

As a final point, a flag has been added in rte_hash_parameters
to indicate if there are new parameters for future versions,
so there is no need to maintain multiple versions
of the existing functions in the future.

48a3991196 hash: replace with cuckoo hash implementation
This patch replaces the existing hash library with another approach,
using the Cuckoo Hash method to resolve collisions (open addressing),
which pushes items from a full bucket when a new entry tries
to be added in it, storing the evicted entry in an alternative location,
using a secondary hash function.

This gives the user the ability to store more entries when a bucket
is full, in comparison with the previous implementation.
Therefore, the unit test has been updated, as some scenarios have changed
(such as the previous removed restriction).

Also note that the API has not been changed, although new fields
have been added in the rte_hash structure (structure is internal now).
The main change when creating a new table is that the number of entries
per bucket is fixed now, so its parameter is ignored now
(still there to maintain the same parameters structure).
The hash unit test has been updated to reflect these changes.

As a last note, the maximum burst size in lookup_burst function
hash been increased to 64, to improve performance.

410d70a3ff mem: warn once if pagemap is unreadable
Newer kernels make this unreadable for security reasons for non-roots.
Running the application will then fill the logs with

  rte_mem_virt2phy: cannot open /proc/self/pagemap

messages.

However, there are cases when DPDK is and should be run as non-root,
without the need for virtual-to-physical address translations: a
typical example is when working with PCAP input/output. This patch
adds a start-time check for /proc/self/pagemap readability, and
directly returns an error code from rte_mem_virt2phy().

This way, there is only a one-time warning at startup instead of
constant warnings all the time.

359e17bf08 app/test: improve hash unit tests
Add new unit test for calculating the average table utilization,
using random keys, based on number of entries that can be added
until we encounter one that cannot be added (bucket if full).

Also, replace current hash_perf unit test to see performance more clearly.
The current hash_perf unit test takes too long and add keys that
may or may not fit in the table and look up/delete that may not be
in the table. This new unit test gets a set of keys that we know
that fits in the table, and then measure the time to add/look up/delete
them.

Note that performance numbers include time to take a random key
from a pre-made array of keys, plus a quick check of return value.
Also, as stated above, expect higher numbers, as all operations
in the new unit tests will be successful, which means that
it will take more time, than mixing both successful and unsuccesful
operations.
