library/io.m:
Note that io.system_error sometimes takes on Win32 error values.
Remove I/O state arguments on `make_err_msg' and
`make_maybe_win32_err_msg'.
Remove `was_error' argument from `ML_maybe_make_err_msg' and
`ML_maybe_make_win32_err_msg' macros, and rename the macros.
Simplify the macros using `MR_allocate_aligned_string_msg' instead of
`MR_offset_incr_hp_atomic_msg'.
Add `is_maybe_win32_error'.
Write `is_error' and `is_maybe_win32_error' in terms of `make_err_msg'
and `make_maybe_win32_err_msg'.
Add `thread_safe' attributes to some `make_err_msg' implementations.
Delete obsolete foreign exported predicates.
library/dir.m:
Simplify `current_directory' implementations. Avoid calling back
into Mercury from foreign code.
Separate out a code path `make_directory_including_parents' from
`make_directory', for C# and Java backends to override instead of
overriding `make_directory' directly. Avoid calling back into Mercury
from foreign code.
Delete the Erlang override of `make_directory'; just use the generic
implementation.
Simplify `make_single_directory'. Avoid calling back into Mercury
from foreign code.
Reduce use of bare ints between Mercury and foreign procs.
Fix `read_entry' using outdated Dir0 variable instead of Dir.
Catch exceptions in Java `read_entry_2'.
Delete many obsolete foreign exported predicates.
mdbcomp/program_representation.m:
Conform to change.
fixup read_entry
