a8e9492560 log-server: implement opcodes and stdout 
This allows the log server to support various opcodes, and gives us
stdout as a suitable command.

bb5bc1d212 refactor i2c to break out the i2c machine to a separate server 
the concurrency issues on I2C are getting hairy, and it was probably a
dubious decision from the start to merge I2C into the LLIO block; but
originally this was motivated by the idea of keeping all the
"miscellaneous slow stuff" in one process to keep the memory footprint
small and make code a bit more readable.

Keeping I2C in the same process space as the LLIO but splitting it
into its own thread and server splits the difference, by giving us
more options to deal with the concurrency, without inflating the size
of the kernel binary and allocating a lot of extra static data.

01e2c7edca migrate to an interrupt-handler only I2C handler 
the amount of time it takes to send messages to initiate each
packet is too slow, and causing timeouts. By handling the I2C
directly in an interrupt handler, we accelerate the bus, at
the expense of no visibility via log/trace messages.
