tools: bpftool: turn err() and info() macros into functions
Turn err() and info() macros into functions. In order to avoid naming conflicts with variables in the code, rename them as p_err() and p_info() respectively. The behavior of these functions is similar to the one of the macros for plain output. However, when JSON output is requested, these macros return a JSON-formatted "error" object instead of printing a message to stderr. To handle error messages correctly with JSON, a modification was brought to their behavior nonetheless: the functions now append a end-of-line character at the end of the message. This way, we can remove end-of-line characters at the end of the argument strings, and not have them in the JSON output. All error messages are formatted to hold in a single call to p_err(), in order to produce a single JSON field.
