tcp: avoid call to soisconnected() on transition to ESTABLISHED
This call existed since pre-FreeBSD times, and it is hard to understand
why it was there in the first place. After 6f3caa6d815 it definitely
became necessary always and commit message from f1ee30ccd60 confirms that.
Now that 6f3caa6d815 is effectively backed out by 07285bb4c22, the call
appears to be useful only for sockets that landed on the incomplete queue,
e.g. sockets that have accept_filter(9) enabled on them.
Provide a new TCP flag to mark connections that are known to be on the
incomplete queue, and call soisconnected() only for those connections.

routing: add abitity to set the protocol that installed route/nexthop.
Routing daemons such as bird need to know if they install certain route

stand: Unbreak FAT32 in loader
This corrects an issue introduced in b4cb3fe0e39a3, where a freshly
allocated `DOS_FS` structure would not be initialized properly before
use in `dos_open`.
In case of FAT32 file systems, this would leave `fs->dirents`
uninitialized and - depending on its content and due to checks in
`parsebs` - prevent mounting the file system successfully.
This particularily impacted the EFI loader, as it was sometimes not
able to read files from a FAT32-formatted EFI partition, including
LoaderEnv (`/efi/freebsd/loader.env`).

most programs in ports are looking for .pc files in order to get the

The ports now also has a way to hide or force a path for pkgconf.
Providing .pc files along with openssl in base will allow (once all
the supported version of FreeBSD has it) so improve the framework to

This will also greatly reduce the number of patches necessary to
workaround the build systems which only knows how to detect where

nfscl: Allow "nolockd" to work for NFSv4 mounts
Commit 40ada74ee1da modified the NFSv4.1/4.2 client so
that it would issue a DestroySession to the server when
all session slots are marked bad. This handles the
case where session slots get broken when "intr" or "soft"
NFSv4 fairly well.1/4.2 mounts are done.
There are two other cases where having an NFSv4.1/4.2
RPC attempt terminate without completion can leave
state in a non-determinate condition.
One is file locking RPCs. If the "nolockd" option is
used, this avoids file locking RPCs by doing locking
locally within the client.
The other is Open locks, but since all FreeBSD Open
locks are done with OPEN_SHARE_DENY_NONE, the locking
state for these should not be critical.
This patch enables use of "nolockd" for NFSv4 mounts,
so that it can be combined with "intr" and/or "soft",
making the latter more usable.
Use of "intr" or "soft" NFSv4 mounts are still not
recommended, but when combined with "nolockd" should
now work fairly well.
A man page update will be done as a separate commit.
