Save/restore regs when reading/writing memory. Add SFR access.
The DPL and ACC registers are used by the memory access code,
so they need to be saved and restored. Stuff them up high in ram for now;
this should probably be fixed to pull them back to the host instead.
Special SFR access is required as not all SFRs are visible in the unified
address space.

s51: get start address from ihx file. re-enable breakpoints after reset.
Use the start of the ihx file when asked to run from 0x0, this lets
sdcdb run programs from ram.
The reset command clears all hw breakpoints, so reset them afterwards.

Switch to libusb-1.0 and use async interface.
The async libusb interface offers substantial performance benefits by not
making each command wait for the reply. This makes talking over this
interface almost reasonable.

Make read_memory debug output use ccdbg_debug.
This makes it default to not being presented, which makes s51 much happier

Add preliminary version of s51, a UI clone of the 8051 emulator.
sdcdb provides source-level debugging using the 8051 emulator, s51. By
emulating that emulator a the UI level, we should be able to get source
debugging right on our target platform.
This is just the preliminary structure for the program with most commands
not yet implemented.
