RFR (XS): 8023134: Rename VM LogFile to hotspot_pid{pid}.log (was hotspot.log)

[Vladimir Ivanov]

Revised version:
http://cr.openjdk.java.net/~vlivanov/8023134/webrev.02/

Turned off LogVMOutput for debug builds by default and implicitly turn 
it on if some flag is specified which may dump useful info in the log 
file.

Best regards,
Vladimir Ivanov
