linked libraries. Only do this for BSS symbols that have a size which avoids
__bss_start. Without this some libraries would be considered unneeded even
though they were providing a B symbol.
- Add in the symbols from crt1.o to cover a handful of common unresolved symbols.
- Consider (C) common data symbols as provided by libraries/crt1.
- Move libkey() function to more appropriate place.

Ran against /usr/local/sbin/pkg:
Before: 25.12 real 12.41 user 33.14 sys
After: 0.53 real 0.49 user 0.13 sys
- Exit with 1 if any missing or unresolved symbol is detected.
- Add option '-U' to skip looking up unresolved symbols.
- Don't consider provided weak objects as unresolved (nm V).

IPv4 addresses/ports.
When doing traffic testing of actual code that /does/ things to the
packet (rather than say, 'bridge.c'), it's typically a good idea to
use a variety of cache-busting and flow-tracking-busting packet
spreads. The pkt-gen method of testing an IP range was to walk
it linearly - which is fine, but not useful enough.
This can be used to completely randomize the source/destination
addresses (eg to test out flow-tracking-busting) and to keep the
destination fixed whilst randomising the source (eg to test out
what a DDoS may look like.)
Tested:
* Intel ixgbe 10G (82599) netmap

pwrite(2) syscalls are wrapped to provide compatibility with pre-7.x
kernels which required padding before the off_t parameter. The
fcntl(2) contains compatibility code to handle kernels before the
struct flock was changed during the 8.x CURRENT development. The
shims were reasonable to allow easier revert to the older kernel at
that time.
Now, two or three major releases later, shims do not serve any
purpose. Such old kernels cannot handle current libc, so revert the
compatibility code.
Make padded syscalls support conditional under the COMPAT6 config
option. For COMPAT32, the syscalls were under COMPAT6 already.
Remove WITHOUT_SYSCALL_COMPAT build option, which only purpose was to
(partially) disable the removed shims.

prematurely with fail_assertion (the testcase doesn't really conform to TAP

core file, much like 'netstat -anr' does it for living kernel.
Right now only AF_INET routing table is printed. AF_INET6 needs to
be done. But the most difficult part of the script (recursion!) is
complete.
