mem: limit use of address hint

The commit below added an address hint as starting address for 64-bit
systems in case an explicit base virtual address was not set by the user.

The justification for such hint was to help devices that work in VA
mode and has a address range limitation to work smoothly with the eal
memory subsystem.

While the base address value selected may work fine for the eal
initialization, it easily breaks when trying to register external memory
using rte_extmem_register API.

Trying to register anonymous memory on RH x86_64 machine took several
minutes, during them the function eal_get_virtual_area repeatedly
scanned for a good VA candidate.

The attempt to guess which VA address will be free for mapping will
always result in not portable, error prone code:
* different application may use different libraries along w/ DPDK. One
  can never guess which library was called first and how much virtual
  memory it consumed.
* external memory can be registered at any time in the application run
  time.

In order not to break the existing secondary process design, this patch
only limits the max number of tries that will be done with the
address hint.
When the number of tries exceeds the threshold the code
will use the suggested address from kernel.

mem: do not use lockfiles for single file segments mode

Due to internal glibc limitations [1], DPDK may exhaust internal
file descriptor limits when using smaller page sizes, which results
in inability to use system calls such as select() by user
applications.

Single file segments option stores lock files per page to ensure
that pages are deleted when there are no more users, however this
is not necessary because the processes will be holding onto the
pages anyway because of mmap(). Thus, removing pages from the
filesystem is safe even though they may be used by some other
secondary process. As a result, single file segments mode no
longer stores inordinate amounts of segment fd's, and the above
issue with fd limits is solved.

However, this will not work for legacy mem mode. For that, simply
document that using bigger page sizes is the only option.

eal: initialize alarms early

On Linux, we currently initialize rte_alarms after
starting to listen for IPC hotplug requests, which gives
us a data race window. Upon receiving such hotplug
request we always try to set an alarm and this obviously
doesn't work if the alarms weren't initialized yet.

To fix it, we initialize alarms before starting to
listen for IPC hotplug messages. Specifically, we move
rte_eal_alarm_init() right after rte_eal_intr_init() as
it makes some sense to keep those two close to each other.

We update the BSD code as well to keep the initialization
order the same in both EAL implementations.

When SR-IOV is set up in switchdev mode and E-Switch is enabled
we have so called VF representors in the system. All representors
belonging to the same E-Switch are created on the basis of the
