netlink: Fix RTA_MULTIPATH on RTM_GETROUTE
Before this patch, netlink never returned RTA_MULTIPATH.
Also, add RTA_MULTIPATH attribute in way that don't confuse
non-mpath support consumers.

routing: Implement merge of nhgrp in new multipath route
Routing subsystem allows creating new multipath routes by
nexthop groups (e.g RTA_MULTIPATH in netlink), in case of
a second nexthop group on the same route, don't panic and
merge the existing nhgrp with new one.

nfscl: Disable use of callbacks for NFSv4.0
The only use for callbacks for NFSv4.0 is delegations
and delegations rarely work well for NFSv4.0 anyhow.
Therefore, this patch disables callbacks for the
NFSv4.0 client. This is the same behavior as
occurred when the nfscbd(8) daemon was not running.
This change allowed a function called nfscl_getmyip()
to be removed from the kernel, which is nice since
maintaining this function was bothersome, due to its
use of routing, etc.

dhclient: Improve server and filename validation
* Don't iterate over each string three times; once is enough.
* Reject control characters (anything below space) in addition to the
double quote and backslash.
* If an unsafe character is encountered, discard the string instead of
rejecting the entire lease.
* If backslashes are encountered in the file name option, convert them
to forward slashes instead of rejecting the option.
* Tweak the warning messages a bit. Looking through the rest of the
code, it seems to me that notes generally end with a period while
warnings generally don't.

md5: Encode non-printable filenames
Encode filenames in the VIS_CSTYLE | VIS_OCTAL style regardless of
output mode. When reading filenames from a checksum file, attempt to
decode them, and use the decoded name unless the decoded name does not
exist but the undecoded one does.
This breaks compatibility with GNU coreutils, which unfortunately uses
a non-reversible encoding when outputting filenames containing
non-printable characters.
While here, drop a sentence about preimage attacks against MD5 and SHA1
from the manual page, as I no longer trust it to be true.

devel/ctags-lsp: Add port
This is an LSP that uses universal-ctags, making it both
language-agnostic and compatible with the vast array of languages
that uctags can parse.
However, that also means that it's limited to the data in a tags file,
meaning things like tracking references is off the table. But, it is,
as the author notes, "better than nothing."
Instructions for enabling the LSP in Neovim and Helix can be found

Document __FreeBSD_version bumps: 1600018 + 1500505-1500509
I only authored the bumps to 1600018 and 1500509, not the previous ones.
Hopefully the description of these previous bumps is accurate.
