use wrappers on all platforms, to make this as consistent as possible x-
platform (in particular, make sure there's at least one \0 byte in
the output buffer).  Also document more of the truth about what these do.

getargs.c, seterror():  Three computations of remaining buffer size were
backwards, thus telling PyOS_snprintf the buffer is larger than it
actually is.  This matters a lot now that PyOS_snprintf ensures there's a
trailing \0 byte (because it didn't get the truth about the buffer size,
it was storing \0 beyond the true end of the buffer).

sysmodule.c, mywrite():  Simplify, now that PyOS_vsnprintf guarantees to
produce a \0 byte.

A system() lookalike that sends commands to ToolServer, by Daniel Brotsky. The semantics aren't enough like system() to add this to the main Lib folder, but it is pretty useful nonetheless for selected people.

slot_tp_descr_set(): When deleting an attribute described by a
descriptor implemented in Python, the descriptor's __del__ method is
called by the slot_tp_descr_set dispatch function.  This is bogus --
__del__ already has a different meaning. Renaming this use of __del__
is renamed to __delete__.

Now sys.executable points to the executable again, in stead of to
the shared library. The latter is used only for locating the python
home.

than the argument string size, copy as many bytes as will fit
(including a terminating '\0'), rather than not copying anything.
This to make it satisfy the C99 spec.

Bugfix candidate.
int_repr():  we've never had a buffer big enough to hold the largest
possible result on a 64-bit box.  Now that we're using snprintf instead
of sprintf, this can lead to nonsense results instead of random stack
corruption.
