sms: Fix gsm_7bit legacy functions return value
The legacy 7bit conversion functions (those without the '_n_' in the name) gave wrong return values on 64 bit platforms due to unproper signed/unsigned conversions and the usage of SIZE_MAX. This patch fixes this by using a smaller max size (see GSM_7BIT_LEGACY_MAX_BUFFER_SIZE, currently set to 64k) for the legacy wrappers and by using unsigned int for max_septets. In addition, there are tests now that check the return values of legacy encoding and decoding. Sponsored-by: On-Waves ehf
