Kill unused `ch' variable within safeputs routine. Also use putchar(3)
instead of printf(3) to output printable characters.

Pointed by Martin Vahlensieck.

- (void)printf() -> printf(); the cast adds clutter for little value.
- fprintf(stdout, ...) -> printf()
- fputs(x, stdout) -> printf(); for consistency.
fputs is twice as fast on atom x5-Z8300@1.44GHz but Amdahl sees a pure printf
tcpdump only 2% slower than a pure fputs (for constant strings) tcpdump
to /dev/null across a 20MB/~170k packet pcap file.

ok dlg@ for fputs and ok tedu@ krw@ deraadt@ a2k19 for the rest

When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

fix microsecond output of timestamp deltas (-tttt)

Remove remaining instances of the register keyword.

lint is dead: delete the trivial uses of /* VARARGS[0-9]+ */

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

Merge printb() fix from ifconfig.c -r 1.157:
Don't increment a pointer *before* testing it for NULL.

Simplify error() and warning() a bit. From Alexey Dobriyan.

add a printer for 802.11 and for additional radiotap headers,
use -y IEEE802_11 or IEEE802_11_RADIO if supported by the driver.

privilege separated tcpdump, joint work with otto@

We live in an ANSI C world. Remove lots of gratuitous #ifdef __STDC__ cruft.

a bit of snprintf cleaning

change timeval to bpf_timeval; 32 bit in size, permitting much greater portability

print day and month using -ttt flag; <canacar@eee.metu.edu.tr>

add relts_print, safeputs and safeputchar

some buffer care; jakob

Add $OpenBSD$. (jakob@ ok)

bring more inline with tcpdump 3.4

- Merge some changes from tcpdump 3.4
-a flag; attempt to convert network and broadcast addresses to names
Improved signal handling
Miscellaneous fixes and typos
OSPF MD5 authentication support

- -X flag; emacs-hexl print (including ascii)

- Add ECN bits to TCP and IP headers

- IKE & IPsec (ESP & AH) support
