those starting at column 0 are temporary debug aids during development.
Some of them I intend to keep in for a version or two. Some of them
I tend to forget later. This is a cleanup of those. Most are removed,
some are promoted to be permanently there - now indicated by proper
indention.
The most important real code chane is the initialization of the
epoll control set. This should just be cosmetic (valgrind warnings),
as all data we actually use already was properly initialized.
epoll_create1() was introduced in Linux kernel 2.6.27. If rsyslog was
compiled on a newer kernel but run on a kernel older than 2.6.27, remote
syslog fails. Apply a runtime check for epoll_create1() and fall back to
epoll_create() in this case.
Bug-Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=617996
so far, we always pulled a single event from the epoll interface.
Now 128, what should result in performance improvement (less API
calls) on busy systems. Most importantly affects imtcp.
