asm-generic: reverse GENERIC_{STRNCPY_FROM,STRNLEN}_USER symbols
Most architectures do not need a custom implementation, and in most cases the generic implementation is preferred, so change the polariy on these Kconfig symbols to require architectures to select them when they provide their own version. The new name is CONFIG_ARCH_HAS_{STRNCPY_FROM,STRNLEN}_USER. The remaining architectures at the moment are: ia64, mips, parisc, um and xtensa. We should probably convert these as well, but I was not sure how far to take this series. Thomas Bogendoerfer had some concerns about converting mips but may still do some more detailed measurements to see which version is better. Cc: "James E.J.
