Fix spelling and grammar errors. Re-organize sections for better explanation

Add a note describing that CXGBE currently only supports binding to PF4.
When using vfio, the probe fails for BAR > 0 after the
commit-id 90a1633b2 (eal/linux: allow to map BARs with MSI-X tables).
While debugging further, found that the BAR region offset and size read from
vfio are u64, but are assigned to uint32_t variables. This results in the u64
value getting truncated to 0 and passing wrong offset and size to mmap for
subsequent BAR regions.
The fix is to use unsigned long for the offset and size.

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.

- Fix interface of pci_map_resource().
- Move path variable of mapped_pci_resource structure to pci_map.
- linuxapp
- Remove redundant error message of linuxapp.
'pci_uio_map_resource()' is implemented in both linuxapp and bsdapp,
but interface is different. The patch fixes the function of bsdapp
to do same as linuxapp. After applying it, file descriptor should be
opened and closed out of pci_map_resource().
