perf_counter tools: Prepare a small callchain framework
We plan to display the callchains depending on some user-configurable parameters.
To gather the callchains stats from the recorded stream in a fast way, this patch introduces an ad hoc radix tree adapted for callchains and also a rbtree to sort these callchains once we have gathered every events from the stream.

perf_counter tools: Define and use our own u64, s64 etc. definitions
On 64-bit powerpc, __u64 is defined to be unsigned long rather than unsigned long long. This causes compiler warnings every time we print a __u64 value with %Lx.
Rather than changing __u64, we define our own u64 to be unsigned long long on all architectures, and similarly s64 as signed long long. For consistency we also define u32, s32, u16, s16, u8 and s8. These definitions are put in a new header, types.h, because these definitions are needed in util/string.h and util/symbol.h.
The main change here is the mechanical change of __[us]{64,32,16,8} to remove the "__". The other changes are:
* Create types.h * Include types.h in perf.h, util/string.h and util/symbol.h * Add types.h to the LIB_H definition in Makefile * Added (u64) casts in process_overflow_event() and print_sym_table() to kill two remaining warnings.

perf_counter: tools: Makefile tweaks for 64-bit powerpc
On 64-bit powerpc, perf needs to be built as a 64-bit executable. This arranges to add the -m64 flag to CFLAGS if we are running on a 64-bit machine, indicated by the result of uname -m ending in "64". This means that we'll use -m64 on x86_64 machines as well.
