tools lib traceevent: Add support for more printk format specifiers The printk format specifiers used in event's print format files extend the standard printf formats. There are a lot of new options related to printing pointers and kernel specific structures. Currently trace-cmd does not support many of them. Support for these new printk specifiers is added to the pretty_print() function: - UUID/GUID address: %pU[bBlL] - Raw buffer as a hex string: %*ph[CDN] These are improved: - MAC address: %pMF, %pM and %pmR - IPv4 adderss: %p[Ii]4[hnbl] Function pretty_print() is refactored. The logic for printing pointers %p[...] is moved to its own function.
