irq_dispatch: Add argument pointer to irq_dispatch
...
Provide a user defined callback context for irq's, such that when
registering a callback users can provide a pointer that will get
passed back when the isr is called.

Move optimized ARM memcpy functions from arch/arm/src/ to libc/machine/. This is necessary for the PROTECTED and KERNEL build modes. Otherwise, memcpy() will be built in to kernel space and not accessible to applications.

Back out most of 34be3e7c3c and update README again. Windows native tools cannot be used with Ubuntu under Windows 10 now. For Cygwin, that support depends on the 'cygpath -w' tool to convert POSIX paths to Windows paths. There is no corresponding tool for Ubuntu under Windows 10.
