hg: jdk7/hotspot/hotspot: 7003707: need to remove (some) system include files from the HotSpot header files

[David Holmes]

FYI this was an urgent changeset that we needed to push through to fix 
an internal build problem caused by the HPI changes. From the CR:

"os_linux.inline.hpp includes sys/ioctl.h for use in the 
socket_available method. The include of ioctl.h causes name space 
pollution on some systems due to subsequent includes (eg termios.h) that 
causes compilation failure. As there is really no reason for 
socket_available to be inlined (it is used as part of a Java -> native 
-> VM invocation sequence, so the extra call is insignificant compared 
to the state transitions) the fix here is to move socket_available into 
os_linux.cpp and delete the inclusion of sys/ioctl.h from 
os_linux.inline.hpp"
