BUG/MINOR: log: improper behavior when escaping log data

Patrick Hemmer reported an improper log behavior when using
log-format to escape log data (+E option):
Some bytes were truncated from the output:

- escape_string() function now takes an extra parameter that
  allow the caller to specify input string stop pointer in
  case the input string is not guaranteed to be zero-terminated.
- Minors checks were added into lf_text_len() to make sure dst
  string will not overflow.
- lf_text_len() now makes proper use of escape_string() function.

This should be backported as far as 1.8.
