Currently, user events are shown using the "hex" output for "safety"
reasons as one cannot trust user events behaving nicely. But the hex
output is not the only utility for safe outputting of trace events. The
print_event_fields() is just as safe and gives user readable output.

Before:
         example-839     [001] .....    43.222244:
00000000: b1 06 00 00 47 03 00 00 00 00 00 00              ....G.......
         example-839     [001] .....    43.564433:
00000000: b1 06 00 00 47 03 00 00 01 00 00 00              ....G.......
         example-839     [001] .....    43.763917:
00000000: b1 06 00 00 47 03 00 00 02 00 00 00              ....G.......
         example-839     [001] .....    43.967929:
00000000: b1 06 00 00 47 03 00 00 03 00 00 00              ....G.......

After:

         example-837     [006] .....    55.739249: test: count=0x0 (0)
         example-837     [006] .....   111.104784: test: count=0x1 (1)
         example-837     [006] .....   111.268444: test: count=0x2 (2)
         example-837     [006] .....   111.416533: test: count=0x3 (3)
         example-837     [006] .....   111.542859: test: count=0x4 (4)
