Tim Newsome db16b3dc5b Call poll at a fixed interval. 
The existing implementation blocks in select() for a fixed amount of
time. This change tracks when the next event (likely poll()) wants to be
run, and uses a shorter timeout in select() if necessary.

Also track all these timeouts using milliseconds as returned by
timeval_ms() instead of `struct timeval` to simplify the code.

This feature is helpful if poll() wants to do something like sample PCs
or memory values for basically the entire time that otherwise OpenOCD
would be hung in select(). See
https://github.com/riscv/riscv-openocd/pull/541 for an example of that.
The RISC-V code using this change will be upstreamed some day, too.
