ipc: remove thread for async requests
Previously, we were using two IPC threads - one to handle messages

To handle replies for an async request, rte_mp_handle woke up the
rte_mp_handle_async thread to process through pthread_cond variable.
Change it to handle asynchronous messages within the main IPC thread.
To handle timeout events, for each async request which is sent,
we set an alarm for it. If its reply is received before timeout,
we will cancel the alarm when we handle the reply; otherwise,
alarm will invoke the async_reply_handle() as the alarm callback.

eal/bsd: support alarm API
Implement EAL alarm API support for FreeBSD. The implementation
is largely identical to that of Linux version, with one key
difference.
The alarm API is a little Linux-centric in that it is expecting
the alarm API to manage alarm timeouts without involvement of the
interrupt thread. This works on Linux because in Linux, there's
timerfd API which allows waiting for timer events on an fd.
On FreeBSD, however, there are no timerfd's, and timer events are
set up directly in kevent. There is no way to pass information from
the alarm API to the interrupt thread, so we also add a little
back-channel magic to get soonest alarm timeout from the alarm API.

memzone: improve zero-length reserve
Currently, reserving zero-length memzones is done by looking at
malloc statistics, and reserving biggest sized element found in those
statistics. This has two issues.
First, there is a race condition. The heap is unlocked between the
time we check stats, and the time we reserve malloc element for memzone.
This may lead to inability to reserve the memzone we wanted to reserve,
because another allocation might have taken place and biggest sized
element may no longer be available.
Second, the size returned by malloc statistics does not include any
alignment information, which is worked around by being conservative and
subtracting alignment length from the final result. This leads to
fragmentation and reserving memzones that could have been bigger but
aren't.
Fix all of this by using earlier-introduced operation to reserve
biggest possible malloc element. This, however, comes with a trade-off,
because we can only lock one heap at a time. So, if we check the first
available heap and find *any* element at all, that element will be
considered "the biggest", even though other heaps might have bigger
elements. We cannot know what other heaps have before we try and
allocate it, and it is not a good idea to lock all of the heaps at
the same time, so, we will just document this limitation and
encourage users to reserve memzones with socket id properly set.
Also, fixup unit tests to account for the new behavior.

app/testpmd: distribute queues to cores
Current topology distribute forwarding streams to lcores by port, this
make unbalanced loading when port number larger than 2:
lcore 0: P0Q0->P1Q0, P0Q1->P1Q1
locre 1: P1Q0->P0Q0, P1Q1->P0Q1
If only one port has traffic, only one locre get fully loaded and the
other one get no forwarding. Performance is bad as only one core doing
forwarding in such case.
This patch distributes forwarding streams by queue, try to get streams
of each port handled by different lcore:
lcore 0: P0Q0->P1Q0, P1Q0->P1Q0
locre 1: P0Q1->P0Q1, P1Q1->P0Q1
