GSM_EXTENSION_LENGTH -> VLR_MSISDN_LENGTH

gsm_subscriber.h contains some legacy cruft, part of which is that the VLR's
max MSISDN length should rather be defined in vlr.h. Same for GSM_NAME_LENGTH
-> VLR_NAME_LENGTH.

Adjust some sms_queue stuff that anyway includes vlr.h already.

Drop gsm_subscriber.h from vlr.h.

Add other (more concise) includes that thus become necessary, since the include
chain vlr.h->gsm_subscriber.h->gsm_data.h is no longer in place.
