* 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.)

* sv/sys_get_status:
Teach sys:get_status/1,2 to call Mod:format_status/2
gen_fsm: Fix format_status/2 to handle Pids
OTP-8324 The ability for the gen_server and gen_fsm callback modules to
format their own state for display under the sys:get_status/1,2
calls has been restored and documented. (Thanks to Steve
Vinoski.)

In the transition from SGML to XML (several releases ago),
bugs were introduced in the documentation, for instance
"\n" replaced by newlines. Correct those bugs.
Also correct double backslashes. They seem to have been introduced very
early in the development of OTP. According to Lars they "solved" a bug
in the generation of HTML &c. Now that standard tools are used instead
of docbuilder, the bug has become visible.

Restore the ability for gen_server and gen_fsm callback
modules to format their own state for display under the
sys:get_status/1,2 calls.
This ability is extremely useful for new behavior modules
based on gen_server or gen_fsm, so that they can display
their status in a more meaningful way than just dumping
the state record. It is also generally useful for applications
wanting to display their gen_server or gen_fsm callback module
state in something other than the default manner.
Also document the previously undocumented the
gen_server:format_status/2 and gen_fsm:format_status/2 optional
callback functions that, if exported by the callback module, are
invoked when sys:get_status/1,2 are called.
Add unit tests to ensure that format_status/2 functions exported
from a gen_fsm callback module and a gen_server callback module
are called when sys:get_status/1,2 are called.

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.

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.

gen_fsm:format_status/2 currently crashes if Name in the process
state is a Pid.
Handle Name in the same way as in gen_server:format_status/2
to eliminate the crash.

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.

* refs/remotes/origin/dgud/array_tests:
Added more tests for array:reset/2.

The on_load feature introduced in R13B03 adds two new internal
BIFs and extends the return value of erlang:load_module/2.

Code coverage was bad for my new optimizations.
