 Version 2.8.4 - October 18, 2012
 - Time for dynamic is in microseconds, not ms.
 - x86_64 builds of mingw32 are not supported directly and should just configure
 as generic mingw32 builds since they're NOT 64 bit.
 - Cope with both ATI stream and AMD APP SDK roots being set when building.
 - Use 3 significant digits when suffix string is used and values are >1000.
 - MMQ new initialisation (that works) and clocking control
 - Get rid of unused warning for !scrypt.
 - Use select on stratum send to make sure the socket is writeable.
 - Cope with dval being zero in suffix_string and display a single decimal place
 when significant digits is not specified but the value is greater than 1000.
 - Pad out the suffix string function with zeroes on the right.
 - Failure to calloc in bin2hex is a fatal failure always so just check for that
 failure within the function and abort, simplifying the rest of the code.
 - Provide locking around the change of the stratum curl structures to avoid
 possible races.
 - Bump opencl kernel version numbers.
 - Remove atomic ops from opencl kernels given rarity of more than once nonce on
 the same wavefront and the potential increased ramspeed requirements to use the
 atomics.
 - Clear the pool idle flag in stratum when it comes back to life.
 - Display correct share hash and share difficulty with scrypt mining.
 - Use explicit host to BE functions in scrypt code instead of hard coding
 byteswap everywhere.
 - Show work target diff for scrypt mining.
 - Ease the checking on allocation of padbuffer8 in the hope it works partially
 anyway on an apparently failed call.
 - Watch for buffer overflows on receiving data into the socket buffer.
 - Round target difficulties down to be in keeping with the rounding of detected
 share difficulties.
 - Dramatically simplify the dynamic intensity calculation by oversampling many
 runs through the opencl kernel till we're likely well within the timer
 resolution on windows.
 - String alignment to 4 byte boundaries and optimisations for bin<->hex
 conversions.
 - In opencl_free_work, make sure to still flush results in dynamic mode.
 - Align static arrays to 4 byte boundaries to appease ARM builds for stratum.
 Version 2.8.3 - October 12, 2012
 - Left align values that are suffix_string generated.
