If the extra field was larger than the space the user provided with
inflateGetHeader(), and if multiple calls of inflate() delivered
the extra header data, then there could be a buffer overflow of the
provided space. This commit assures that provided space is not
exceeded.

The CAM 'maxio' is a 'pessimized' size, assuming 4k pages and one page
per segment. Since there are at most 63 segments in a transaction with
this driver, and one would necessarily be the indirect segment marker,
clamp the maxio to the minimum of maxphys (tunable) or (63 - 1) pages
(248k).

The fsck_ffs(8) utility made sanity checks of critical superblock
fields by comparing the values of those fields in the standard
superblock againt the values of those fields in the last alternate
superblock. The code for validating a superblock now cover all the
checked fields as well as many more. Further the checks done are
far more comprehensive. So we now drop the alternate superblock
checks as they no longer provide value. Dropping these checks also
eliminates the need to read the alternate superblock.
This has already been done for most files that have the Foundation as
the only listed copyright holder. Do it now for files that list
multiple copyright holders, but have the Foundation copyright in its own

This code was written prior to snprintf being in the then libstand (now
libsa). Since we have it, use it for extra safety. The code already
tries to be safe, but since we have snprintf as well, the added layer of
protection will suffice. The current code reserves 16 bytes (plus a NUL)
at the end for worst case of inet_ntoa, which is still a little
pessimal, but safe from overflow.

Summary:
This allows installing packages that depend on kerberos libraries
without pulling in all the binaries. It also moves libgssapi to runtime
to allow installing kerbereos libraries without adding a dependancy on
the large utilities package. It makes sense to put libgssapi in runtime
rather than kerberos-lib since this is a plugin layer which is intended
to support any GSS-API mechanisms, not just kerberos.
A good example of a package which uses kerberos libraries without
needing the kerberos utilities is sshd. This uses the kerberos GSS-API
libraries to implement its GSSAPIAuthentication option.

CTF integers have an explicit width and so can be used to represent
bitfields. Bitfield types emitted by ctfconvert(1) share the name of
the base integer type, so a struct field with type "unsigned int : 15"
will have a type named "unsigned int".
To avoid ambiguity when looking up types by name, add a suffix to names
of bitfield types to distinguish them from the base type. Then, if
ctfmerge happens to order bitfield types before the corresponding base
type in a CTF file, a name lookup will return the base type, which is
always going to be the desired behaviour.

When it was inline it made sense to depend on the existing nested check
in KTRUSERRET() rather than adding a new td_flags flag. However, since
we now have a TDA_KTRACE flag anyway, we might as well check it and
avoid the call.

Make most AST handlers dynamically registered. This allows to have
subsystem-specific handler source located in the subsystem files,
instead of making subr_trap.c aware of it. For instance, signal
delivery code on return to userspace is now moved to kern_sig.c.
Also, it allows to have some handlers designated as the cleanup (kclear)
type, which are called both at AST and on thread/process exit. For
instance, ast(), exit1(), and NFS server no longer need to be aware
about UFS softdep processing.
The dynamic registration also allows third-party modules to register AST
handlers if needed. There is one caveat with loadable modules: the
code does not make any effort to ensure that the module is not unloaded
before all threads processed through AST handler in it. In fact, this
is already present behavior for hwpmc.ko and ufs.ko. I do not think it
is worth the efforts and the runtime overhead to try to fix it.

socket using in6_pcblookup_local(), and if the socket can also connect
to IPv4 (the INP_IPV4 vflag is set), check for IPv4 matches as well.
Otherwise, we can allocate a port that is used by an IPv4 socket
(possibly one created from IPv6 via the same procedure), and then
connect() can fail with EADDRINUSE, when it could have succeeded if
the bound port was not in use.
