Eal common timer doesn't compile under Windows.
Compilation log:
error LNK2019:
unresolved external symbol nanosleep referenced in function rte_delay_us_sleep
error LNK2019:
unresolved external symbol get_tsc_freq referenced in function set_tsc_freq
error LNK2019:
unresolved external symbol sleep referenced in function set_tsc_freq
The reason was that some functions called POSIX functions.
The solution was to move POSIX dependent functions from common to Unix.
