fix that the GPU name is printed before the name is querried from OpenCL

The cpu miner backend uses the wrong ranges of nonces instead of using `[startNonce,startNonce + nonce_chunk)`
(startNonce,startNonce + nonce_chunk]` is used. This will results in an overlap with nonces used by the gpu back-ends.

revert the change that the OpenCl function `rotate` is used instead of `SKEIN_ROT`

- Eliminate modulus math (It runs slow inside microcode).
- Convert whatever the hell was going on into a rotate op. Like... Someone kinda reinvented the wheel in order to do a simple rotate.

reduce memory usage to 1GiB for NVIDIA devices with <=6 SMX

Ignore any affinity >=64 and throw a warning.

- if the intensity is zero than do not suggest a config
- remove the links to old issues

update VEGA names

bug was introduced with #67

- increase the L3 sanity check to 2GiB
- fix usage of byte instead of KB

Changed capitalization of "macOS"

Squashed the commit

Occassionally the auto adjust doesn't find enough memory and the
intensity is detected too low and aligned to 0 with the compute units.
This patch fixes this situation by issuing a warning with a suggestion
to set environment vars and then ignoring the alignment to 0

Missing include


1

- fix cuda9.1 compile (remove includ eof device_functions.hpp/ removed with cuda9.1)
- remove NVIDIA Volta gpus for MAC OSX

handle all error codes from the cuda api calls.

Makes casting more explicit.

When compiled with VS2017, the negative applied to the uint wait
time is ignored. Fixed by casting first.

- fix indention

Be more conservative with the auto suggestion.

- increase bfactor if `smx <= 6`
- limit memory for pascal < GTX1070 to 2GiB
- limt memory for pascal <= GTX1080 to 4GiB

- add macro `CUDA_CHECK_MSG_KERNEL` and `CUDA_CHECK_MSG`
- add suggestion of typicle errors can be solved

Fix nonce allocation

The "low_power_mode" option in config.txt can be set to numeral values
between 1 and 5. A value of 5 seems optimal on certain processors
with large L4 cache.

Make k unsigned.

Clean up the x-mas tree

unroll AES round by hand to help the compiler to optimize the command queue

Change the default for strided index. Th euser feedback shows that strided_index = true will give a view hashes more per second.

Allow to change the indexing used to address the hash scratchpad memory.

- add option `strided_index` for each gpu

- add option `sync_mode`
- update auto suggestion and jconf

fix #191

lauch bounds must be placed before the return type but after the template paramater
