[dpdk-dev,v2,1/6] Move EAL common functions

  Changes in v2
1. Remove rte_dump_registers() function since it is not implemented.
2. Fix comment for _rte_exit()

eal_debug.c has no difference between Linux and BSD, move
into common directory.
Rename eal_debug.c to eal_common_debug.c
Makefile changes to reflect file move and name change.
Fix checkpatch warnings.

The subject matter for all of the patches in the series should be more detailed.
Just posting move EAL components to common directly isn't overly informative

I will change the subject and make it more explicit. In addition, I was
thinking of adding function names which are moved as part of commit message
so that it is easier for everyone to check what is moved rather than going
through the patch. Do you think it would be helpful??

Thanks.
