xentrace: fix tracing for 64bit guests
Xen tracing some times ago used to put values of type 'long' into the
trace buffer. This has changed to uint32_t. Some trace points log
virtual addresses, which get cropped to 32bit in this case. There were
some inline functions to handle at least PF_XEN and VMEXIT, which
caused a lot of code duplication. The attached patch fixes several
issues:
1. fix and extend tools/xentrace/formats
2. Fix xentrace_format to handle up to 7 parameters
3. create convenience macros to properly log long values
4. remove the inline functions in hvm/trace.h and replace them by macros
5. Change the CPUID trace to work correctly
6. group HVM trace points enable mechanism
I used a similar approach as in PV tracing with bit 8 indicating 64bit
pointers.
