Introduced `#define HAS_CUSTOM_BAUD` for platforms which have appropriate implementation. Moving that `#if defined(__linux__) && defined(USE_CUSTOM_BAUD)` ... stuff out of `term.c`and put it to `termios2.h` / `custbaud_bsd.h` headers. Moving that platform specific `#ifdefs` to the platform specific headers helps removing duplicate complex `#ifdef` constructs. The both platform specific headers then do `#define HAS_CUSTOM_BAUD` to signal that custom baudrate support is implemented for the target platform. I'd tested all above mentioned platforms with both USE_CUSTOM_BAUD unset and set to check if that refactoring don't raises unexpected issues.
