TS-306: Fix file privilege elevation to work with log rotation.
This fixes several issues.
The biggest is DAC bypass privilege elevation. Because `traffic_server` is
invoked in multiple ways (full deployment, standalone, via `gdb`, etc.)
sometimes the process is privileged when the logfiles are bound and sometimes
it is not. The existing elevation mechanism does not work if the process is
already privileged because it incorrectly removes the privileges when it lowers
privileges. I have changed this to save the current capability set and restore
it on lowering so that it works in both cases.
I tweaked the buffering on the logfiles to avoid log messages apparently
stopping in the middle.
I changed an argument naming to reserve leading underscores for class
member variables.
