compate/clipped-write.c: large write(2) fails on Mac OS X/XNU
Due to a bug in the Darwin kernel, write(2) calls have a maximum size
of INT_MAX bytes.
Introduce a new compat function, clipped_write(), that only writes
at most INT_MAX bytes and returns the number of bytes written, as
a substitute for write(2), and allow platforms that need this to
enable it from the build mechanism with NEEDS_CLIPPED_WRITE.
Set it for Mac OS X by default. It may be necessary to include this
function on Windows, too.
