sqlite3_trace() sometimes does not invoke its callback

Changes

  1. Change foundin to "3.8.6"
  2. Change icomment to:

    The callback to sqlite3_trace() is suppose to be invoked for every SQL statement that is run by the VDBE. But sometimes the callback will be suppressed. If the prepared statement is marked as expired (which can happen, for example, if the RHS of an expression like "x GLOB ?1" is rebound and X is an indexed text column) then the callback is not invoked. This can be seen in the shell by running:

    .trace stderr
    .tables
    

    The SELECT statement that implements the ".tables" command is not traced.

    This problem appears to have existed since 2012-10-03, version 3.7.15 and check-in [39f763bfc04174ee0fe2cdf6a92]. The problem was discovered during internal testing and has not been observed in the wild.
