DECnet support currently assumes certain conditions instead of
checking for them explicitly. The following code checks if
dnet_htoa() is available, possibly in libdnet and also verifies
there is no declaration for the function in <netdnet/dnetdb.h>
before it decides to provide a substitute.
Use const more.
Use EXTRACT_* macros more.
Use TCHECK* more.
Use tok2str() to replace some home-grown workalikes.
smb:
- Get rid of private types, use tcpdump-defined types
- Rename fdata and fdata1 to smb_fdata and smb_fdata1 to avoid conflict
with IRIX library function.
(which doesn't actually seem to be significantly more efficient than
"strdup()", at least not to the extent that it makes any difference to
"tcpdump"), modified to use the BSD "strdup()", rather than the old
"savestr()", on platforms that lack "strdup()".
