ftruncate() may severely delay the start of a dump process for certain UMS devices, and the write speed differences when using the SD card seem to be negligible. Other changes include: * FileWriter: add log messages throughout all class methods. * log: update generic log macros to use __PRETTY_FUNCTION__ instead of __func__. * log: add logFormatFunctionName() function, which takes an input __PRETTY_FUNCTION__ string and parses the info we need from it. * log: update _logWriteFormattedStringToLogFile() and logWriteFormattedStringToBuffer() functions to reflect the other changes.
