Subject: [PATCH] Read config into memory and pass its content to tinyxml2
 (#253)

tinyxml2 does not support to read from a named pipe, since it uses seek to
figure out the file size. In the case of a pipe this is not possible.

Reading the file content into memory and passing the content to tinyxml2 allows
to mitigate this problem.
