Small patch to set "hw.model" by SoC ChipCommon ID. On BCM4718 it will be BCM4716, because 4716 is core for 4716,4717 & 4718.

The generated C output for aicasm_scan.l defines yylineno already, so
references to it from other files should use an extern declaration.
The STAILQ_HEAD use in aicasm_symbol.h also provided an identifier,
causing it to both define the struct type and define a variable of that
struct type, causing any C file including the header to define the same
variable. This variable is not used (and confusingly clashes with a
field name just below) and was likely caused by confusion when switching
between defining fields using similar type macros and defining the type
itself.

The bsdinstall script target did not have the infrastructure to fetch
distfiles from a remote server the way the interactive installer does
on e.g. bootonly media. Solve this by factoring out the parts of the
installer that deal with fetching missing distributions into a new
install stage called 'fetchmissingdists', which is called by both the
interactive and scripted installer frontends.
In the course of these changes, cleaned up a few other issues with
the fetching of missing distribution files and added a warning if
fetching the MANIFEST file, which is used to verify the integrity of
the distribution files. We should at some point add cryptographic
signatures to MANIFEST so that it can be fetched safely if not present
on the install media (which it is for bootonly media).

A problem was reported via email, where a large (130000+) accumulation
of NFSv4 opens on an NFSv4 mount caused significant lock contention
on the mutex used to protect the client mount's open/lock state.
Although the root cause for the accumulation of opens was not
resolved, it is obvious that the NFSv4 client is not designed to
handle 100000+ opens efficiently. When searching for an open,
usually for a match by file handle, a linear search of all opens
is done.
Commit 3f7e14ad93 added a hash table of lists hashed on file handle
for the opens. This patch uses the hash lists for searching for
a matching open based of file handle instead of an exhaustive
linear search of all opens.
This change appears to be performance neutral for a small number
of opens, but should improve expected performance for a large
number of opens.
This commit should not affect the high level semantics of open
handling.

ktrace(2) may toggle trace points in any of
1. a single process
2. all members of a process group
3. all descendents of the processes in 1 or 2
In the first two cases, we do not permit the operation if the process is
being forked or not visible. However, in case 3 we did not enforce this
restriction for descendents. As a result, the assertions about the child
in ktrprocfork() may be violated.
Move these checks into ktrops() so that they are applied consistently.
Allow KTROP_CLEAR for nascent processes. Otherwise, there is a window
where we cannot clear trace points for a nascent child if they are
inherited from the parent.

When collecting kernel stacks for a target process, if the process
adds a thread between the two calls to sysctl, ignore the additional
threads. Previously, procstat would print only a useless error
message. Now, it prints a consistent snapshot of the stacks.
We know that snapshot is already stale, but it could still be stale
even with a more complex fix to reallocate and retry, so such a fix
is hardly worth the effort.

The last set of commits fixed both a panic (in rack) and an ACK-war (in freebsd and bbr).
However there was a missing case, i.e. where we get an out-of-order FIN by itself.
In such a case we don't want to leave the FIN bit set, otherwise we will do the
wrong thing and ack the FIN incorrectly. Instead we need to go through the
tcp_reasm() code and that way the FIN will be stripped and all will be well.

Before that it was even 16 bits, but macro handling conversion between

and 8 bits mode size.
This breaks some libpmc API methods, like pmc_capabilities.
Since we only have 4 modes and MODE field is a number (not a bitfield)
this patch moves 4 bits of mode to extend the CLASS field.
