Entirely untested code. Get is most definitely wrong for nonexistent keys.
Fixup Get() to possibly do something valid on unset keys.

Implement GetK, GetKQ
Makefile: Add missing phony targets to PHONY
Undefine _FORTIFY_SOURCE for release builds

LTO and _FORTIFY_SOURCE interact very, very badly on ubuntu. Ubuntu

Change starsha to use '\n' instead of std::endl in most cases

We keep the flush when we're in exceptional states to force the messages out ASAP
