An on_load function is supposed to return 'true' to indicate
that the module should be loaded, and 'false' if it should be
unloaded. But returning any other term, as well as causing an
exception, will also unload the module.
Since we don't like boolean values mixed with other values,
change the expected return value as follows:
* If 'ok' is returned, the module will remain loaded and become
callable.
* If any other value is returned (or an exception is generated),
the module will be unloaded. Also, if the returned value is
not an atom, send a warning message to the error_logger
(using error_logger:warning_msg/2).
The new interpretation of the return value means that an on_load
function can now directly return the return value from
erlang:load_nif/2.

NIF function prototypes in order to allow more than 3 function
arguments. Also an incompatible change in the return value of
erlang:load_nif/2. Added support for references, floats and term
comparison in NIFs. Read more in the documentation of erl_nif and
erlang:load_nif/2.

The correct value for the second argument to erlang:split_binary/2
(Pos) is 0, not 1.

* mh/to_erl-error-messages:
to_erl: Include strerror(errno) in error messages
OTP-8325 to_erl will now include the system error string in error messages
to make it easier to understand what the real problem is. (Thanks
to Magnus Henoch.)

The MIB compiler in the snmp applications formats its warnings slightly
differently, so we'll need to update the regexp that should match the
expected output.

* ks/dialyzer-wx-fix:
dialyzer: make -wx always start the SMP emulator

The erlang:make_stub_module/3 BIF (which is only used for
loading native code) does not zero the word that points out
an on_load routine (if any). As that word most proably will
contain a non-zero value, the erlang:module_loaded/1 BIF will
think that the module has an on_load routine which has not
returned and will always return 'false'. That in turns causes
various problems for the native code test cases.

to_erl likes to print the message "No running Erlang on pipe ...",
no matter what the problem actually was. The wording might make
you forget that you just need to run to_erl as another user,
for example.
With this change, to_erl will print the system error message
in addition to its own.
Example output:
No running Erlang on pipe pipes/erlang.pipe.5: Permission denied
(wrong user, wrong permissions, etc)
No running Erlang on pipe pipes/erlang.pipe.5: No such device or address
(this actually means "no running Erlang")
No running Erlang on pipe pipes/erlang.pipe: No such file or directory
(not only is there no running Erlang, there are also no pipes at all)

The wx application will only work in the SMP emulator,
so the -wx option for 'dialyzer' must force the -smp
option when starting the emulator.
Make sure that -wx in *any* position on the command
line (not only as the first argument) forces the
SMP emulator.
