* @date Tue Nov 8 18:19:10 2011
*
* @brief This log system supports wrapping multiple outputs into one
* log message. This is useful for outputting variable-length logs
* without additional memory overhead (the buffer for concatenating
* the message), e.g. exception stack trace, which cannot be printed
* by a single log calling without the help of an additional buffer.
* Avoiding additional memory buffer is useful for resource-constraint
* systems. It can minimize the impact of log system on applications
* and logs can be printed even when no enough memory is available.
* Functions with prefix "_" are private functions. Only macros that
* are not start with "_" are exposed and can be used.
