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.
