Initialize or create a BufferReader from a file path. The whole file is read into memory.

Parameters

br	buffer to initialize, if NULL then a new BufferReader is created.
filepath	path of the file to read.
failureMessage	message to LOG() in case of open failure. Must contain 2 placeholders 's' for the filepath and the error message.
failureLevel	log level to use in case of failure.

Returns

BufferReader with the file contents, NULL in case of error, in which case a LOG() is emitted.
