uemacs uses a lot of legacy stuff, which causes warnings with newer
toolchains.
This makes it build reasonably warning-free.

Joerg Scheurich reported that there's a buffer overflow in readin() for
long path component names. He's not wrong.
When fixing that, and then checking there's nothing else obviously wrong
with valgrind, I also noticed it complains about overlapping strcpy().
So add a hacky version of strscpy(), which (a) handles overlapping, and
(b) has the proper strscpy() semantics.
Just say no to strncpy and strlcpy, both of which are terminally broken
interfaces.
And stop stripping the binary. The time when the size of the uemacs
binary was a big deal is long past, and it made valgrind harder.

Heh. My new UHD monitor makes it easy to have more than 127 lines of
text. I guess the 'char' could be an unsigned char, but quite frankly,
trying to save a couple of bytes per open editor window seems a bit
excessive these days. So just make it 'int'.

Fix the following warning:
input.c: In function ‘getstring’:
input.c:590: warning: ignoring return value of ‘mkstemp’, declared with attribute warn_unused_result
This add usage.c module for die function.
This also add wrapper.c module for the xmkstemp that is wrapper function
around the original mkstemp function.
Both module codes was largelly based on git, linux and sparse codes.

This patch fixes out-of-box build on Mac OS X by using "uname -s" to detect the
underlying OS and fixing up defines accordingly.

Compiles on Mac OS X 10.6.4.
setmode() is renamed to setemode() to avoid conflict with OS X's unistd.h's
setmode().
Modify Makefile to enable the appropriate DEFINES to compile on Mac OS X.

I keep typoing 'Makefile' instead of 'makefile'. I guess it's hard-wired to
the brain by now so just rename the damn thing.
