pointers

opt_fail_only mode.

versions missing it)
- Suppress warning about "succeeded" not being used in finish_req_in_progress
for now
- Bugfix: Always give the get_work thread a curl, regardless of other
outstanding curls in use
- Bugfix: Failover after even a single job-request failure (or else it takes
too long on timeouts)
- Bugfix: Need to remove and re-add curl easy handles from multi to start a new
request
- Access total_submitting under mutex lock to avoid any potential races, and
increment it as soon as we queue the submission up
- Just leave the submit_work thread running persistently

it
- Bugfix: Now that stage_work is trying to manipulate staged_work in the same

exits use the kill_work and quit paths.
- Set successful connect to true on auth stratum to allow summary on exit from
single stratum pool.

thread, making it possible to serialise all requests minimising the number of
getworks requested or local work generated. Use a pthread conditional to wake up
the thread whenever work is removed to generate enough work to stay above the
watermark set by opt_queue. Remove all remnants of the old queueing mechanism,
deleting the now defunct queued count.

have longpoll aka solo mining.
- Check for correct absence of opt_fail_only in cnx_needed.
- Remove unused variable.
- The specification for stratum has been elaborated to say that a changed diff
applies only to new work so do not retarget when submitting shares.
- Suspend stratum connections to backup pools when there is no requirement to
potentially grab work from them.
- Rename rename_thr to RenameThread to match cgminer

- Tidy up device error counts
- Only increase gpu engine speed by a larger step if the temperature is below
hysteresis instead of increasing it to max speed.
- Convert pool not responding and pool alive message on backup pools to verbose
level only since they mean a single failed getwork.
- Use stratum block change from backup pools as an alternative to longpoll for
pools that don't support LP.
- Round some more static string arrays to 4 byte boundaries.
- There is no need for the static arrays to be larger than required, so long as
they're 4 byte aligned to appease ARM.
- Hash1 is only used by the CPU mining code and never changes so remove it from
the work struct and bypass needing to process the value for all other mining.
