Update the mlx4 core and mlx4en(4) modules towards Linux v4.9.
Background: The coming ibcore update forces an update of mlx4ib(4) which in turn requires an updated mlx4 core module. This also affects the mlx4en(4) module because commonly used APIs are updated. This commit is a middle step updating the mlx4 modules towards the new ibcore.
This change contains no major new features.
Changes in mlx4: a) Improved error handling when mlx4 PCI devices are detached inside VMs. b) Major update of codebase towards Linux 4.9.
Changes in mlx4ib(4): a) Minimal changes needed in order to compile using the updated mlx4 core APIs.
Changes in mlx4en(4): a) Update flow steering code in mlx4en to use new APIs for registering MAC addresses and IP addresses. b) Update all statistics counters to be 64-bit. c) Minimal changes needed in order to compile using the updated mlx4 core APIs.

Flexible and asymmetric allocation of EQs and MSI-X vectors for PF/VFs.
Previously, the mlx4 driver queried the firmware in order to get the number of supported EQs. Under SRIOV, since this was done before the driver notified the firmware how many VFs it actually needs, the firmware had to take into account a worst case scenario and always allocated four EQs per VF, where one was used for events while the others were used for completions. Now, when the firmware supports the asymmetric allocation scheme, denoted by exposing num_sys_eqs > 0 (--> MLX4_DEV_CAP_FLAG2_SYS_EQS), we use the QUERY_FUNC command to query the firmware before enabling SRIOV. Thus we can get more EQs and MSI-X vectors per function. Moreover, when running in the new firmware/driver mode, the limitation that the number of EQs should be a power of two is lifted.

Move the ConnectX-3 and ConnectX-2 driver from sys/ofed into sys/dev/mlx4 like other PCI network drivers. The sys/ofed directory is now mainly reserved for generic infiniband code, with exception of the mthca driver.
- Add new manual page, mlx4en(4), describing how to configure and load mlx4en.
- All relevant driver C-files are now prefixed mlx4, mlx4_en and mlx4_ib respectivly to avoid object filename collisions when compiling the kernel. This also fixes an issue with proper dependency file generation for the C-files in question.
- Device mlxen is now device mlx4en and depends on device mlx4, see mlx4en(4). Only the network device name remains unchanged.
- The mlx4 and mlx4en modules are now built by default on i386 and amd64 targets. Only building the mlx4ib module depends on WITH_OFED=YES .
