1215da39ee modminer: Don't delay 2nd+ FPGAs during work restart 
Add primary_thread boolean to threads to identify a single one as the "primary" thread for shared-resource multithreading.
This is needed since ModMiners use multiple threads to interface with independent hashing components.

2384d0fbc6 Removed idle mode... again!? 
Changed work_reset rate to every 100ms & use defines rather than numerics.
Change total sleep time to 4300ms after performance testing/measurement (now good to 916MH/s).
Changed timeout to 15s - Throttle time is 15s.
Added support for 'Busy' when submitting work.
Improved logging text to include device identifier.
Added a thread_enable api function, called when a thread is re-enabled.
... and removed useless re-init inside scanhash.
Use modminer introduced mutex.

5ad942d187 Faster hardware can easily outstrip the speed we can get work and submit shares when using only one connection per pool. 
Test the queued list to see if any get/submits are already queued and if they are, start recruiting extra connections by generating new threads.
This allows us to reuse network connections at low loads but recuit new open connections as they're needed, so that cgminer can scale to hardware of any size.

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.

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.

405fcd76ca Delayed responses from testing pools that are down can hold up the watchdog thread from getting to its device testing code, leading to false detection

e0b0a6c030 Modularize code: main.c -> device-cpu + device-gpu 
This patch is an initial attempt to re-structure cgminer source
code from its monolithic design (with nearly all code being
concentrated in main.c) to a more modular one.

In this first stage, the conditionally compiled functions for
GPU and CPU mining were extracted into dedicated files:
 * device-cpu.h and device-cpu.c covering WANT_CPUMINE functions
 * device-gpu.h and device-gpu.c covering HAVE_OPENCL functions

The main.c file is left untouched as reference, while the
remainder without the extracted parts is located in cgminer.c.

The Makefile.am has been updated to use the re-structured
source files for the build.

Above pure re-structuring *NO* functional modifications were
made. The sources were tested to compile and run on on a
current Linux system with working CPU and GPU mining
(Bitforce not tested due to loack of hardware).
