PR10099: Extend %M directive to support hexdumping large buffers
This patch will make %M directive dump the variable width
buffer in hex format instead of returning uint64_t number
as before.
* runtime/vsprintf.c: Modify %M directive.
* stap.1.in: Update description.
* testsuite/systemtap.printf/memory1.stp: Add test case.
