26ab7346e3 Implement a new pool strategy, BALANCE, which monitors work performed per pool as a rolling average every 10 minutes to try and distribute work evenly over all the pools. 
Do this by monitoring diff1 solutions to allow different difficulty target pools to be treated equally, along with solo mining.
Update the documentation to describe this strategy and more accurately describe the load-balance one.

8745ba1e6d Windows' timer resolution is limited to 15ms accuracy. This was breaking dynamic intensity since it tries to measure below this. 
Since we are repeatedly sampling similar timeframes, we can average the gpu_us result over 5 different values to get very fine precision.

Idle is only set by pgadisable, so GPU/CPU is unaffected.

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.

4cd973264f Create discrete persistent submit and get work threads per pool, thus allowing all submitworks belonging to the same pool to reuse the same curl handle, and all getworks to reuse their own handle. 
Use separate handles for submission to not make getwork potentially delay share submission which is time critical.
This will allow much more reusing of persistent connections instead of opening new ones which can flood routers.
This mandated a rework of the extra longpoll support (for when pools are switched) and this is managed by restarting longpoll cleanly and waiting for a thread join.

b9d197dee8 Refactor the CPU scanhash_* functions to use a common API. Fixes bugs. 
- Before, some returned bool, and others returned int (which was then turned
  into a bool with a comparison); now, everything returns a bool
- Before, some set hashes_done to nonce - 1 when a share was found and others
  set it to nonce + 1 or 2. This caused some algorithms to scan/submit shares
  twice with the new cpu_scanhash function. Now, it has all been replaced with
  last_nonce, which is set to the final nonce checked by the scanhash_* func.
- VIA needs the full data, and cannot use midstate. All the others were
  expecting midstate and data+64 for their parameters. Now, we pass midstate
  and the full data pointer, and let the scanhash_* function choose which to
  use.

1536e085da Increase efficiency of slow mining threads such as CPU miners dramatically. 
Do this by detecting which threads cannot complete searching a work item within the scantime and then divide up a work item into multiple smaller work items.
Detect the age of the work items and if they've been cloned before to prevent doing the same work over.
If the work is too old to be divided, then see if it can be time rolled and do that to generate work.
This dramatically decreases the number of queued work items from a pool leading to higher overall efficiency (but the same hashrate and share submission rate).

Change this logic to perform full validation inside minerd, so that work may
be resumed more quickly if hash > target.

Should be an equivalent transformation, with no behavior changes.
