Subject: [PATCH] dmidecode: Do not let --dump-bin overwrite an existing file
Make sure that the file passed to option --dump-bin does not already
exist. In practice, it is rather unlikely that an honest user would
want to overwrite an existing dump file, while this possibility
could be used by a rogue user to corrupt a system file.

Subject: [PATCH] dmidecode: Split table fetching from decoding
Clean up function dmi_table so that it does only one thing:
* dmi_table() is renamed to dmi_table_get(). It now retrieves the
DMI table, but does not process it any longer.
* Decoding or dumping the table is now done in smbios3_decode(),
smbios_decode() and legacy_decode().
No functional change.
A side effect of this change is that writing the header and body of
dump files is now done in a single location. This is required to
further consolidate the writing of dump files.

Subject: [PATCH] dmidecode: Write the whole dump file at once
When option --dump-bin is used, write the whole dump file at once,
instead of opening and closing the file separately for the table
and then for the entry point.
As the file writing function is no longer generic, it gets moved
from util.c to dmidecode.c.
One minor functional change resulting from the new implementation is
that the entry point is written first now, so the messages printed
are swapped.

Subject: [PATCH 1/1] dmioem: Fix segmentation fault in dmi_hp_240_attr()
pr_attr() does not accept a NULL format string. glibc can deal with
it, but FreeBSD's libc chokes on it.
Display the attributes as a list instead. Pack the attribute name and
status into a single formatted string that can be passed to
pr_list_item(). That's arguably a hack, but it's cheap, non-intrusive,
and works nicely in the end.
Bug reported by Scott Benesh (Microchip).
