8745ba1e6d Windows' timer resolution is limited to 15ms accuracy. This was breaking dynamic intensity since it tries to measure below this.

9c648c1749 Bugfix: Calculate nsec in nmsleep correctly 
The old algorithm (msecs * 1000000) - (sec / 1000000000) gets total nsec,
including seconds, since the sec/1e9 should be multiplying. It's also
vulnerable to easy overflows. Using ldiv gets the quotient and remainder
in a single operation (at least on x86) and avoids overflow.

eda382990a Create one longpoll thread per pool, using backup pools for those pools that don't have longpoll. 
Use the work created from the longpoll return only if we don't have failover-enabled, and only flag the work as a longpoll if it is the current pool.
This will work around the problem of trying to restart the single longpoll thread on pool changes that was leading to race conditions.
It will also have less work restarts from the multiple longpolls received from different pools.

44bcb69ccd Fixing leak in resp_hdr_cb 
Memory is allocated for key and val, and longpoll address, when found, is stored in the header_info and prevented from being freed there. This pointer is stored during pool probing but once that's done it was just being lost.

Not so visible but also leaking was the refuse reason string.

e0fec35751 modularized logging, support for priority based logging 
Functions related to logging are extracted into dedicated source files
for better maintainability.

The existing low-level logging API is extended with a generalized scheme
providing log functions log_{error, warning, notice, info, debug} that
log messages based on a global opt_log_level.

opt_log_level for now is set to LOG_NOTICE and might be modified via
command line options or config files in future releases.
