librte_pmd_mlx4.so needs to be linked with libibverbs otherwise, the PMD is
not able to open Mellanox devices and the following message is printed by
testpmd at startup
"librte_pmd_mlx4: cannot access device, is mlx4_ib loaded?".
Applications dependency on libibverbs are moved to be only valid in static
mode, in shared mode, applications do not depend on it anymore,
librte_pmd_mlx4.so keeps this dependency and thus is linked with libibverbs.
MLX4 cannot be supported in combined shared library because there is no clean
way of adding -libverbs to the combined library.

Move malloc inside eal and create a new section in MAINTAINERS file for
Memory Allocation in EAL.
Create a dummy malloc library to avoid breaking applications that have
librte_malloc in their DT_NEEDED entries.
This is the first step towards using malloc to allocate memory directly
from memsegs. Thus, memzones would allocate memory through malloc,
allowing to free memzones.

TX queue elements (struct txq_elt) contain WR and SGE structures required by
ibv_post_send(). This commit replaces them with a single pointer to the
related TX mbuf considering that:
- There is no need to keep these structures around forever since the
hardware doesn't access them after ibv_post_send() and send_pending*()
have returned.
- The TX queue index stored in the WR ID field is not used for completions
anymore since they use a separate counter (elts_comp_cd).
- The WR structure itself was only useful for ibv_post_send(), it is
currently only used to store the mbuf data address and an offset to the
mbuf structure in the WR ID field. send_pending*() callbacks only require
SGEs or buffer pointers.
Therefore for single segment mbufs, send_pending() or send_pending_inline()
can be used directly without involving SGEs. For scattered mbufs, SGEs are
allocated on the stack and passed to send_pending_sg_list().
