Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Allow disabling debugging messages. Add test for LWASM_NODEBUG symbol to disable compiling the actual debug message handling code. Also, prevent building the debug message arguments if the debug level is not going to display the message anyway. This comes at the possible expense of larger code due to wrapping the debug_mesage() function in a macro that tests the debug level directly. This should prevent calling expensive things like building a dump of an expression when it is not required.
