Replace win filename s with unix equivalent

Evaluate commands passed to "exec" and "system" to expand any $variables before executing command.


client/mysqltest.c:
  do_exec, do_system 
   - call do_eval on the command to be executed in order to expand any $variables
   - Remove old subst_env_var and my_popen, not needed anymore
  Rewrite 'replace_strings' into 'replace_strings_append'
   - copy whole strings instead of byte by byte copy
   - insert result directly inito dynamic_string, no need to check if out 
     string needs to be realloced for every byte.
   - Add comments and DBUG_PRINT's
  New function 'fix_win_paths', detect filenames in win format that should be converted 
  do_eval
  - Only set "escaped" if next char is \ or $
