Move 'get_disk_info()' function into 'compat/'. Although Scalar-specific code is generally not part of the main Git tree, 'get_disk_info()' will be used in subsequent patches by additional callers beyond 'scalar diagnose'. This patch prepares for that change, at which point this platform-specific code should be part of 'compat/' as a matter of convention. The function is copied *mostly* verbatim, with two exceptions: * '#ifdef WIN32' is replaced with '#ifdef GIT_WINDOWS_NATIVE' to allow 'statvfs' to be used with Cygwin. * the 'struct strbuf buf' and 'int res' (as well as their corresponding cleanup & return) are moved outside of the '#ifdef' block.
