Define a target_addr_t type to support 32-bit and 64-bit addresses at the same time. Also define matching TARGET_PRI*ADDR format macros as well as a convenient TARGET_ADDR_FMT. In targets that are 32-bit (avr32, nds32, arm7/9/11, fm4, xmc1000) be least invasive by leaving the formatting unchanged apart from the type; for generic code adopt TARGET_ADDR_FMT as unified address format. Don't silently change gdb formatting here, leave that to later. Add COMMAND_PARSE_ADDRESS() macro to abstract the address type. Implement it using its own parse_target_addr() function, in the hopes of catching pointer type mismatches better. Add '--disable-target64' configure option to revert to previous 32-bit target address behavior.
