 * Name: exec_builtin
 *
 * Description:
 *   Executes builtin applications registered during 'make context' time.
 *   New application is run in a separate task context (and thread).
 *
 * Input Parameter:
 *   filename  - Name of the linked-in binary to be started.
 *   argv      - Argument list
 *   redirfile - If output if redirected, this parameter will be non-NULL
 *               and will provide the full path to the file.
 *   oflags    - If output is redirected, this parameter will provide the
 *               open flags to use.  This will support file replacement
 *               of appending to an existing file.
 *
 * Returned Value:
 *   This is an end-user function, so it follows the normal convention:
 *   Returns the PID of the exec'ed module.  On failure, it.returns
 *   -1 (ERROR) and sets errno appropriately.
