        src/sys/dev/usb: moscom.c u3g.c uark.c ubsa.c ubsa_common.c uchcom.c
            ucomvar.h uftdi.c ugensa.c uhmodem.c uipaq.c ukyopon.c umct.c
            umodem.c umodem_common.c uplcom.c uslsa.c uvisor.c uvscom.c

Log Message:
clean up ucom / ucom-parent interface slightly:

- document what the ucom_methods{} callbacks argument are and that
  they are all optional.
- remove almost all methods being assigned to NULL, as they are all
  C99 initialisers and thus don't need NULL assignments.
- ucom_get_status() callback always has lsr/msr pointers as valid.
  remove all tests for not NULL in these functions.
