Subject: [PATCH] Revert "Make gcc compiler happy about ifname string
truncation."
This change dropped the "." from between the physical interface name and
the vlan number, making fipvlan created vlan names incompatible with
fcoeadm commands that ended up calling get_pci_dev_from_netdev in
lib/sysfs_hba.c (fcoeadm -i). That requirement should be fixed, but for
now lets deal with the fipvlan naming regression.
safe_makevlan_name isn't doing anything that can't be handled by
checking the return from snprintf
This reverts commit eee875e6526786031ec916274deec92148677c38.

Subject: [PATCH] 21 string-op truncation, format truncation, and format
overflow errors
This isn't a full audit of the source, just addressing anything gcc 10.2 flagged.
There's two basic mitigations added, depending on the likelyhood and severity
of truncation to correct functioning.
1) When a truncation is unlikely (copy between two IFNAMSIZ buffers) or
non-critical (output formating) I forced a null-terminiation at the buffer end
after a strncpy to satisfy the compiler.
2) Where truncation needs proper detection and handling, I used snprintf and
corrected the error checking.
