RFR: JDK-8029776 - Solaris code cleanup

[Gerald Thornbrugh]

Hi,

I am a member of the Oracle Hotspot group and there is an initiative to 
clean up
things like uninitialized variables and unclosed file descriptors in 
JDK8. This is a
backport of fixes that have already been putback into JDK9. I have run 
UTE and
JPRT tests on Solaris machines without proflems. The below webrev show 
the fixes for
the Solaris area.

Bug:

Webrev:

Please review my changes and let me know if you have questions.

Thanks,

Gerald Thornbrugh
