The qemu_log function has no equivalent behaviour. This introduces support for a "program name" in the new messages API, which will be included by default for all binaries. This change tweaks the output of the error_report function, adding a space between the program name and the location info. The qemu_log function will gain the program name. This can be easily seen with the 'log' trace backend, and how it is now more closely matching error_report output.
