upper-bounding it to the size of the initial socket buffer lower-bound it
to the smallest MSS we accept. Ideally we'd use the actual MSS information
here but it is not available yet.
For socket buffer auto sizing to be effective we need room to grow the
receive window. The window scale shift is determined at connection setup
and can't be changed afterwards. The previous, original, method effectively
just did a power of two roundup of the socket buffer size at connection
setup severely limiting the headroom for larger socket buffers.

p->p_emuldata is properly initialized in the time when the child can run.
Do not set p->p_emuldata to NULL when the process is exiting.
It does not make any sense and only costs 2 mutex operations.
Do not lock emul_data to unlock it on the very next line.
Comment on possible race while there.
Reparent all procs that are part of a threading group but not its leaders
to init and SIGCHLD init to finish the zombies off. This fixes zombies
left after opera's exit. [1]
There is no need to lock p_em in the linux_proc_init CLONE_THREAD
case because the process cannot change the address of the p_em->shared
because its currently running this code path.
Move assigning of em->shared outside emul_shared_lock.

buffer resizing, etc.) that was here since eon. Free all (unmanaged)
allocated buffer through sndbuf_destroy() in case we forgot to call
sndbuf_free(). For a managed buffer (mostly hw specific managed buffer),
either provide CHANNEL_FREE() method with appropriate return value to
invoke semi-automatic sndbuf_free() or simply do it on their own. If
everything is failed, sndbuf_destroy() will come to the rescue as a
final measure.

This should fix the run time bustage observed on recent -CURRENT whilst
mounting a MSDOS filesystem with non-default locale/code page:
link_elf: symbol msdosfs_fileno_free undefined
KLD msdosfs_iconv.ko: depends on msdosfs - not available
using the callers UID instead of the GID when performing group
operations. This could allow users to determine group quota
information for groups they are not a member of in some cases.
Rename the "uid" parameter in ufs_quotactl to "id" to better show
that it is used for more than just the uid, and to be more in line
with the naming conventions in the other quota routines.

locking in preparation for adding a watchdog handler (callouts must
not use sleepable locks). This required shuffling memory and
interrupt allocation to the attach routine rather than if_ioctl so as
to avoid potential sleeps while bringing up the interface.
This is not a functional change.
IN_LINKLOCAL() tests if an address falls within the IPv4 link-local prefix.
IN_PRIVATE() tests if an address falls within an RFC 1918 private prefix.
IN_LOCAL_GROUP() tests if an address falls within the statically assigned

IN_ANY_LOCAL() tests for either of IN_LINKLOCAL() or IN_LOCAL_GROUP().
As with the existing macros in the FreeBSD netinet stack, comparisons
are performed in host-byte order.

SOCK_DGRAM (i.e. UDP), respect the value configured earlier. This allows
TCP NFS root mounts using e.g. the boot.nfsroot.options="tcp" tunable.
In this case some of the connection parameters like the retry timer were
previously set appropriately for TCP but inappropriately for the UDP
socket that was actually used, leading to e.g. extremely long recovery
times (O(hours)) after a nfs server reboot.
