Distinguish WRITE and WRITE_NO_RSP in gatt access cb

Re: newtmgr image upload nrf51dk disconnects with reason=8

I believe the setting to tweak is the slave latency, and have some empirical evidence to back that up. Increasing supervision timeout doesn't help if the timeout is at the link manager level (because of a blocking call, say), while increasing slave latency allows the peripheral to take more than

I run mynewt natively on Win10, with msys2-x64 and native arm-gcc toolchain. The develop branch of both the newt tool and newt-core is in pretty good state now, wrt Windows support, as long as you have some form of binutils available. The only outstanding change is for the bsp scripts, I believe.
