Moving to core-libs-dev to allow for wider review. As Dan mentions, we've been looking to remove the Solairs-specific interruptible I/O for a long time.

Hi,
Interruptible I/O on Solaris has been highly problematicand undercut portability. And the long term plan is to remove it completely from JDK. In JDK6, the VM option, UseVMInterruptibleIO, was introduced as part of a phase-out plan to allow developers/customers to disable it. In JDK7, the default value of UseVMInterruptibleIO flag was changed to"false" to make Solaris blockingI/O operations uninterruptible by Java thread interruptsby default.
The last stepof this phase-out plan is to remove the feature completely. And it is good to do it now in JDK8. In this fix, I removed all related codes in IO area by replacing JVM_* functions with direct system calls. Please help review the proposed fix. Similar changes in networking area will be done via a different bug.
