RFR(xxs): 8211845: A new switch to control verbosity of hs-err files

[Thomas Stüfe]

Hi all,

may I please have reviews for this patch:

Bug: https://bugs.openjdk.java.net/browse/JDK-8211845

which is just the implementation of:

CSR: https://bugs.openjdk.java.net/browse/JDK-8211846

cr: http://cr.openjdk.java.net/~stuefe/webrevs/8211845-extensive-error-reports-switch/webrev.00/webrev/

We wanted a switch which would allow us to add types of output to the
hs-err files which may under standard conditions considered to be
either too lengthy or too security sensitive. This switch would be off
under normal conditions but could be switched on in trusted
environments or when one does not care about the size of hs-err files.
For further information, please see the CSR.

Please note that I refrained from adding "enable security sensitive
output" or similar text to the switch description. The reason is that
this would implicitly promise that by default, when this switch is off
(like, now), the hs-err file does not contain security sensitive
information. And that we just cannot promise. After all, we already
print out register contents etc.

Thanks, Thomas
