[syslog-ng]file() versus pipe() for kernel logging

[Amodiovalerio Verde]

It seems the only difference between file() and pipe() is the way files a=
re opened.

file() open files in read only , while pipe() open them in =
read-write.

There's also defined a source and a destination fifo() tha=
t is just another name for pipe().
