Currently, page deallocation might fail if allocator cannot get page
fd, which will leave VA space still mapped, and will also not mark
page as free.
Fix page deallocation function to always unmap space before trying
to get rid of the page itself, and always mark page as free even if
page deallocation failed.

When we ask to reserve virtual areas, we usually include
alignment in the mapping size, and that memory ends up
being wasted. Wasting a gigabyte of VA space while trying to
reserve one gigabyte is pretty expensive on 32-bit, so after
we're done mapping, unmap unneeded space.

Mapping size is a 64-bit integer, but mmap() will accept size_t for

The code aimed to pick and remember the value of
mempool ops name from EAL command line arguments does not
copy the string and remembers the pointer provided
by getopt_long() directly. The latter could be clobbered
later and result in reading wrong mbuf pool ops name
by rte_mempool library.
Typically, this flaw could be avoided by using strdup()
to remember the string value of the option.

rx_q fifo can only be released by kernel thread. There may be
mbuf leaks in rx_q because kernel threads are randomly stopped.
When the kni is released and netdev is unregisterd, convert the
physical address mbufs in rx_q to the virtual address in free_q.
By the way, alloc_q can be processed together to speed up the
release rate in userspace.
In my test, it is improved from 300-500ms with a mempool that has
131072 mbufs to 10ms(regardless of the specifications).

extract objects not compiled from source for a target. To keep backward
compatibility, a "recursive" keyword-arg was added to make this optional.
The value is "false" by default for now, but will change to "true" in
