Changes in v4
None

Changes in v3
Changed subject to be more explicit on file name inclusion.

Changes in v2
None

Changes in v1
eal_thread.c has minor differences between Linux and BSD, move
entire file into common directory.
Use RTE_EXEC_ENV_BSDAPP to differentiate on minor differences.
Rename eal_thread.c to eal_common_thread.c
Makefile changes to reflect file move and name change.
Fix checkpatch warnings.
