6144aff95c Don't duplicate code for SCTP, just use the ones used for UDP and TCP.
This fixes a bug with link local addresses. This will require and
upcoming change in the kernel to bring SCTP to the same behaviour
as UDP and TCP.

7df95e052c When calling netstat -Laptcp the local address values are not aligned
with the corresponding entry in the table header.
r295136 increased the value width from 14 to 32 without the corresponding
change to the table header. This commit adds the change to the table
header width.

In the case the width is less than 0, we are returning an uninitialized

aaa09777e1 New sendfile(2) syscall. A joint effort of NGINX and Netflix from 2013 and
up to now.

The new sendfile is the code that Netflix uses to send their multiple tens
of gigabits of data per second. The new implementation features asynchronous
I/O, when I/O operations are launched, but not awaited to be complete. An
explanation of why such behavior is beneficial compared to old one is
going to be too long for a commit message, so we will skip it here.

Additional features of new syscall are extra flags, which provide an
application more control over data sent. The SF_NOCACHE flag tells
kernel that data shouldn't be cached after it was sent. The SF_READAHEAD()
macro allows to specify readahead size in pages.

The new syscalls is a drop in replacement. No modifications are required
to applications. One can take nginx binary for stable/10 and run it
successfully on head. Although SF_NODISKIO lost its original sense, as now
sendfile doesn't block, and now means something completely different (tm),
using the new sendfile the old way is absolutely safe.

44973a75bb Update dependencies after r291406 added libelf to libkvm.
Unfortunately filemon/meta mode tracks all indirect dependencies here
since ld(1) is reading libelf when linking in libkvm.  Churn would be
reduced if this was able to be limited to direct dependencies.

2ab2ea6fbd Replace DPSRCS that work fine in SRCS.
This is so that 'make depend' is not a required build step in these
files.

DPSRCS is overall unneeded.  DPSRCS already contains SRCS, so anything
which can safely be in SRCS should be.  DPSRCS is mostly just a way to
generate files that should not be linked into the final PROG/LIB.  For
headers and grammars it is safe for them to be in SRCS since they will
be excluded during linking and installation.

The only remaining uses of DPSRCS are for generating .c or .o files that
must be built before 'make depend' can run 'mkdep' on the SRCS c files
list.  A semi-proper example is in tests/sys/kern/acct/Makefile where a
checked-in .c file has an #include on a generated .c file.  The
generated .c file should not be linked into the final PROG though since
it is #include'd.  The more proper way here is just to build/link it in
though without DPSRCS.  Another example is in sys/modules/linux/Makefile
where a shell script runs to parse a DPSRCS .o file that should not be
linked into the module.  Beyond those, the need for DPSRCS is largely
unneeded, redundant, and forces 'make depend' to be ran.  Generally,
these Makefiles should avoid the need for DPSRCS and define proper
dependencies for their files as well.

An example of an improper usage and why this matters is in usr.bin/netstat.
nl_defs.h was only in DPSRCS and so was not generated during 'make all',
but only during 'make depend'.  The files including it lacked proper
depenencies on it, which forced running 'make depend' to workaround that
bug.  The 'make depend' target should mostly be used for incremental build
help, not to produce a working build.  This specific example was broken in
the meta build until r287905 since it does not run 'make depend'.

The gnu/lib/libreadline/readline case is fine since bsd.lib.mk has 'OBJS:
SRCS:M*.h' when there is no .depend file.

df2a89db2b - Add -W flag support for network column in intpr() (-i flag) and
routepr() (-r flag).  It is too narrow to show an IPv6 prefix
  in most cases.

- Accept "local" as a synonym of "unix" in protocol family name.

- Show a prefix length in CIDR notation when name resolution failed in
  netname().

- Make routename() and netname() AF-independent and remove
  unnecessary typecasting from struct sockaddr.

- Use getnameinfo(3) to format L2 addr in intpr().

- Fix a bug which showed "Address" when -A flag is specfied in pr_rthdr().

- Replace cryptic GETSA() macro with SA_SIZE().

- Fix declarations shadowing local variables with the same names.

- Add more static, remove unused header files and variables.
