 Version 3.5.0 - 29th September 2013
 - Add magic init sequence required on BF1 devices to get them mining on windows.
 - usbinfo.devlock is only ever write locked so convert it to a mutex
 - Icarus remove unneeded opt_debug tests due to applog being a macro
 - Icarus - CMR shouldn't wait the full timeout due to handle sharing
 - We should only yield once in cg_wunlock
 - Provide a function to downgrade a cglock from a write lock to an intermediate
 variant.
 - Deuglify use of _PARSE_COMMANDS macro expansions.
 - Deuglify use of usb parse commands macro in usbutils.
 - Use the driver add commands macros in api.c to avoid individually listing
 them.
 - Separate out asic fpga and opencl drivers in the driver parse commands macro
 for use individually as needed.
 - Use macro expansion in usb_find_devices to avoid explicitly listing them all.
 - Use macro expansion to iterate over all the drivers without explicitly writing
 them out in usbutils.c
 - Iterate over the bitfury offsets in order of decreasing likelihood.
 - Reattach the kernel driver on linux on usb_uninit.
 - Attach the kernel driver on failure to usb init on linux.
 - libusb kernel driver operations are only available on linux.
 - There is no need to get the external prototypes for drivers in cgminer.c any
 more.
 - Remove unnecessary gpu_threads initialisation.
 - Put avalon last in the sequence of adding drivers to prevent it trying to
 claim similar chip devices on startup.
 - Use macro expansion to iterate over all device drivers without needing to
 explicitly code in support in all places. Pass a hotplug bool to the detect()
 function to prevent opencl trying to hogplug GPUs.
 - Forward declare all device drivers in miner.h avoiding the need to export them
 everywhere else.
 - Add a noop function for driver detect when it's missing.
 - Reuse the DRIVER_ macros to avoid having yet another definition for DRV_
 - Use macro expansion to generate extern device_drv prototypes.
 - Create a macro list of drivers to enable easier addition of further drivers.
 - There is no point setting the BF1 preferred packet size to the maximum since
 it will do so automatically.
 - icarus ensure all cmr interfaces are initialised properly
 - usbutils - fix USBDEBUG warnings
 - Remove unnecessary steps in communicating with BF1 and just use USB interface
 1.
 - usbutils - usb_bulk_transfer fix the buf/data fix
 - usb_bulk_transfer - use the allocated buffer
 - Set preferred packet sizes per interface on BF1.
 - usbutils allow PrefPacketSize per endpoint
 - Remove magic control sequences on open/close on BF1 and just flush the read
 buffers.
 - Check return codes in getinfo and reset and fail as needed in BF1.
 - Check return code for bitfury_open and release resources properly on failed
 initialisation.
 - Abstract out flushing of interrupt reads in BF1 devices.
 - Perform interrupt read after close message on BF1 as per serial close.
 - Perform interrupt read flush as per serial open on BF1 devices.
 - Add information for 2nd USB interface on BF1 devices and choose interface 1
 for bulk transfers.
 - usbutils - bulk transfer copy test fix
 - usbutils - add USBDEBUG for usb_bulk_transfer
 - Add more read_ii variants to usbutils.
 - Name remainder of BFU usb commands used.
 - Use submit_tested_work in bitfury driver to avoid unnecessarily re-testing the
 work for validity.
 - Abstract out work submission once it's been tested, to be used by drivers that
 do their own internal validity testing.
 - Store the hash2 array in struct work for further reuse.
 - usbutils - which_intinfo not requried
 - Use the test_nonce function within submit_nonce and store the uint32
 corresponding to hash2 37 for further use.
 - usbutils - interfaces must all be on one handle - ep implies the interface
 - avalon stats use exact type
 - Only set share diff if we've confirmed it's a share first.
 - Update ASIC-README for bitfury devices.
 - Use an array of offsets when checking nonces in bitfury_checkresults
 - Limit the duration we wait for reads in BF1 based on time already elapsed to
 account for other delays such as work restart messages or out of work.
 - Minimise size of serial string we copy in BF1 stats to avoid overflow.
 - Implement basic API stats for BF1 and increase array of results to check for
 the rare straggling result.
 - Space debug output for bf1 to separate from numerals.
 - Abstract out the bitfury open close and reset functions and use them on
 reinit.
 - Rename BF1 devices BF1
 - Check for work restart, breaking out early after usb reads in BF1.
 - Do not lose the first sets of results from BF1.
 - There is no point checking for results from the next round of work on BF1.
 - Last result returned by BF1 is an end of results marker so ignore it.
 - restart_wait should return 0 if thr_restart is true.
 - Remove unused code by bitfury driver since current driver uses serialised
 scanhash.
 - Meter out return of estimated hashes in BF1 to smooth out visible hashrate.
 - Optimise inner scanhash loop for bf1.
 - Add yet another backup work for triple buffering of work in bf1 to account for
 extra late results returned and don't check nonce offsets which appear to never
 return.
 - Name the work request and result usb commands for BF1
 - Define a mandatory upper limit to waiting for reset and data on BF1 based on
 full nonce duration.
 - Decrease usb buffering to verbose logging.
 - Add in first draft for a serialised work model sending/receiving data for BF1
 devices.
 - Add complete close sequence to bf1 as it happens on serial.
 - Provide a bitfury identify function for bf1.
 - Reliably extract BF1 information at startup and reset the device.
 - Add commands for getting BF1 bitfury info
 - Add magic BF1 bitfury open and close control sequences.
 - Add BF1 detection code to bitfury driver.
 - Create basic placeholders for bitfury driver code.
 - Add bf1 device information to usbutils to enable device detection.
 - Add basic defines for building for bitfury devices.
 - Add redfury device to udev rules.
 - avalon: display the FPGA controller version on API
 - pool_active uninitialised_var rolltime
 - Use macro expansion to only need to define usb enums and commands in one
 place.
 - usbutils saving incorrect overflow buffer
 - ignore libusb.la and *.lo on linux
 - icarus support CMR with no extensions
 - usbtils - interfaces dont work yet in libusb windows so disable for that only
 - Provide a --disable-libcurl config option to build support for stratum mining
 only.
 - Fix the api-example.c compile under Linux
 - usbutils - only release the device once - for the first intinfo
 - usbutils set_interface is no longer valid
 - ubsutils interfaces much each have their own handle
 - usbutils kernel_detach should use the interface number
 - usbutils - allow the driver to change which_intinfo
 - Reset quotas on load balance for all pools at the same time to avoid running
 out during selection and unintentionally dropping to fallback.
 - Break out of select pool from a common point for appropriate debug messages
 and to avoid further tests.
 - usbutils correct/reverse CMR product numbers
 - usbutils specifically track handles and interfaces
 - change drivers to use usb_interface() - required for multi interface change
 - usbutils - allow a device to use multiple interfaces (and better var names)
 - Cast -1 to (char) to cope with different default char types on ARM.
 Version 3.4.3 - 13th September 2013
 - Put corefoundation and iokit separate in ldflags for darwin.
