Several of the constant length string built in address types don't
check to see if the buf_len passed in is long enough to write
the string.
This can cause buffer overflows, e.g. with a custom column with
many FT_ETHER fields.
Use host byte-order with AT_NUMERIC to make it more generic
and practical.
Change openSAFETY to pass addresses in host byte-order (the
previous code assumed they were in little-endian).
Plus a few cleanups.
Add a numeric address type analog to StringZ for
protocols who only use numeric values as addresses
with no further handling.
e.g. IAT protocols which only enumerate the devices
Replace:
g_snprintf() -> snprintf()
g_vsnprintf() -> vsnprintf()
g_strdup_printf() -> ws_strdup_printf()
g_strdup_vprintf() -> ws_strdup_vprintf()
This is more portable, user-friendly and faster on platforms
where GLib does not like the native I/O.
Adjust the format string to use macros from intypes.h.
Most of the time, the return value tells us nothing useful, as we've
already decided that we're perfectly willing to live with string
truncation. Hopefully this keeps Coverity from whining that those
routines could return an error code (NARRATOR: They don't) and thus that
we're ignoring the possibility of failure (as indicated, we've already
decided that we can live with string truncation, so truncation is *NOT*
a failure).

This will copy an address's "byte format" into a buffer. The original
intended design is for export_pdu functionality, which tries to do
this "manually" for many address types (and creates undesired dependencies)
The default functionality if a "byte format function" isn't provided
(currently the case for all address types) is a memcpy of the address
data. Providing "address to byte" functions to aid export PDU
functionality will be provided later.

Have address_to_name() be a routine that takes an address and returns a
string with a "sufficiently long" lifetime for use in columns, using the
address type's addr_name_res_str routine for most address types, rather
than having a too-small set of address types wired into it. It replaces
both the internal solve_address_to_name() routine and get_addr_name(),
and can, for example, handle the special WLAN address types rather than
leaving them unresolved even with an ethers file.
