[PATCH] cleanup: time.h, times.h, timex.h and jiffies.h

[PATCH] cleanup: time.h, times.h, timex.h and jiffies.h

This patch moves some definitions among time.h, times.h, timex.h and
jiffies.h.  The purpose is to sort all jiffies related functions to
jiffies.h, to get rid of the cyclic dependency between time.h & timex.h and
to move all #include lines to the start of the header files.
