Description:
Problem: When the windows version of mysqlbinlog reads 4.1 binlogs containing LOAD DATA INFILE, it outputs backslashes as path separators in filenames. However, the output is typically piped to a client, and client expect forward slashes.

How to repeat:
run 'mtr binlog_old_versions' under windows

Suggested fix:
Replace '\\' by '/' in filenames.

Patch approved provided comments of new function annotated to include the limitation that it will incorrectly convert '\\' to '/', in case someone uses '\\' in a pathname under unix (per Mats).

Documented as follows in the 5.1.23-ndb-6.2.14 changelog:

        When the Windows version of mysqlbinlog read 4.1
        binlogs containing LOAD DATA INFILE statements, it
        output backslashes as path separators, causing problems for
        client programs expecting forward slashes. In such cases, it now
        converts \\ to / in directory paths.

Left status as PQ pending merges to mainline trees.
