Workaround for problem where cygwin's bash/sh randomly fails with error 128 which

mainly occurs on win2003 64bit.
 - Execute "exec" commands directly with cmd.exe and replace "--exec echo ..." with "--exec .\echo.exe ..." 


client/mysqltest.c:
  Workaround the problem with "echo" in windows not behaving like "echo" in Unix.
  - Replace "--exec echo ..." with "--exec <path to mysqltest>\echo.exe" thus forcing
    use of our own echo implementation which baheves like on Unix.
  - The above change makes it possible to remove the need to execute all --exec's
    inside cygwin. Add ifdefs to only use use cygwin's bash conditionally
mysql-test/lib/mtr_misc.pl:
  Add function for converting to the OS's native format
mysql-test/mysql-test-run.pl:
  Convert path to executables to "windows native" (c:\<path>\) instead of "mixed"(c:/<path>) mode
  necessary for pipes and redirects to work properly in cmd.exe
client/echo.c:
  New BitKeeper file ``client/echo.c''
