Some of the header guard names in ipmitool duplicated with the ones in
freeipmi.
* ipmitool/ipmi_fru.h and freeipmi/fru/ipmi-fru.h both uses IPMI_FRU_H
* ipmitool/ipmi_sdr.h and freeipmi/sdr/ipmi-sdr.h both uses IPMI_SDR_H
* ipmitool/ipmi_sel.h and freeipmi/sel/ipmi-sel.h both uses IPMI_SEL_H
This is problematic as including the 1st will prevent the 2nd from being
included, leading to the loss of any declarations, inline definitions,
or other "#includes" in the 2nd header.
For example, including ipmitool/ipmi_sel.h and freeipmi/freeipmi.h fails
to build.
$ cat test.c
#include <ipmitool/ipmi_sel.h>
#include <freeipmi/freeipmi.h>
$ gcc test.c -I${HOME}/src/oss/ipmitool/include
In file included from /usr/include/freeipmi/freeipmi.h:90,
from test.c:2:
/usr/include/freeipmi/sdr/oem/ipmi-sdr-oem-intel-node-manager.h:48:44: error: unknown type name 'ipmi_sdr_ctx_t'; did you mean 'ipmi_fru_ctx_t'?

Remove header guards and use "#pragma once" instead. In this way, we
don't have to do manual management to avoid name clashes.
* src/plugins/lan/md5.h is left as is being an external header
originally.
* src/plugins/imb/imbapi.h is a convoluted header consisting of multiple
header guards. Let's just add "#pragma once" and leave header guards
as is for now.
