I found there are some problems in the tracing parser when I investiage the root
cause of issues mentioned in below patch.
https://patchwork.kernel.org/patch/10132953/

This serials can fix them.

v3: Polish commit msg from Steven Rostedt.
v2:
- Drop 1 old patch and add a new one.
- Stop parsing when '\0' found.

Changbin Du (3):
tracing: detect the string termination character when parsing user
input string
tracing: clear parser->idx if parser gets nothing
tracing: make sure the parsed string always terminates with '\0'
