Add `command_len` argument to the Simple IPC API.

In my original Simple IPC API, I assumed that the request
would always be a null-terminated string of text characters.
The command arg was just a `const char *`.

I found a caller that would like to pass a binary command
to the daemon, so I want to ammend the Simple IPC API to

s/ammend/amend/

take `const char *command, size_t command_len` and pass
that to the daemon.  (Really, the first arg should just be
a `void *` or `const unsigned byte *` to make that clearer.)

The reader is left wondering why you didn't also change it to `const
void *` (or one of the other choices) while at it.

Note, the response side has always been a `struct strbuf`
which includes the buffer and length, so we already support
returning a binary answer.  (Yes, it feels a little weird
returning a binary buffer in a `strbuf`, but it works.)
