Each entry in ObsoleteFiles.inc adds to the time `make delete-old` and
friends take to run. Perl was removed from the FreeBSD base system a
very long time ago (FreeBSD 5); source updates have not been supported
from that version for years.
Perl was a single component responsible for thousands of entries so
provides significant benefit with little effort/investigation required.
We could still use a more comprehensive cleanup to remove old entries.
Also add an UPDATING note (with wordsmithing by imp) indicating that
`make delete-old` is required along each step of a source upgrade from
an old, unsupported release.

up to par with the Linux pam_access(8).
Like the Linux pam_access(8) our pam_login_access(8) is a service module
for pam(3) that allows a administrator to limit access from specified
remote hosts or terminals. Unlike the Linux pam_access, pam_login_access
is missing some features which are added by this commit:
Access file can now be specified. The default remains /etc/access.conf.
The syntax is consistent with Linux pam_access.
By default usernames are matched. If the username fails to match a match
against a group name is attempted. The new nodefgroup module option will
only match a username and no attempt to match a group name is made.
Group names must be specified in brackets, "()" when nodefgroup is
specified. Otherwise the old backward compatible behavior is used.
This is consistent with Linux pam_access.
A new field separator module option allows the replacement of the default
colon (:) with any other character. This facilitates potential future
specification of X displays. This is also consistent with Linux pam_access.
A new list separator module option to replace the default space/comma/tab
with another character. This too is consistent with Linux pam_access.
Linux pam_access options not implemented in this commit are the debug
and audit options. These will be implemented at a later date.

Japanese keyboards traditionally use 0x5c for
both Japanese yen sign key and backslash key.
While a Japanese yen sign is depicted on the keytop,
most of Japanese expect that the scan code 0x7d gives
a backslash (0x5c), not a Japanese yen sign (0xa5).
This is because JIS X 0201 encoding (aka ISO/IEC 646-JA,
an extended version of ASCII which is very popular
in Japan) has Japanese yen sign at 0x5c and
no backslash. On the other hand, ISO/IEC 8859-1
has Japanese yen sign at 0xa5. This difference has
caused a confusion after Unicode became popular since
ISO/IEC 10646 adopted 8859-1 for the plane 0.

```
The first few are because `->` has a higher precedence than `*`, so the
expressions should use `(*bp)->foo` instead. I also renamed the
variable to `bpp` to make it clearer that it is a pointer-to-pointer.
The last one is because `sc->as_currentbio` is already a `struct bio *`,
there is no need to dereference `bp` there.
Last but not least, I would really suggest rewriting the
`altera_sdcard_io_start_internal()` function to just return success or
failure, so the caller can decide to set `bp` to NULL.

Thanks to Christian Wright for reporting the issue for the userland
stack and providing a fix for the priority scheduler.

It was used only to store the bounds of each swap device. However,
since swblk_t is a signed 32-bit int and daddr_t is a signed 64-bit
int, swp_pager_isondev() may return an invalid result if swap devices
are repeatedly added and removed and sw_end for a device ends up
becoming a negative number.
Note that the removed comment about maximum swap size still applies.

putpages' allocation of swap blocks is done under the global sw_dev
lock. Previously it would drop that lock before inserting the allocated
blocks into the object's trie, creating a window in which swap blocks
are allocated but are not visible to swapoff. This can cause
swp_pager_strategy() to fail and panic the system.
Fix the problem bluntly, by allocating swap blocks under the object
lock.

swap_pager_swapoff_object()'s goal is to allocate pages for all valid
swap blocks belonging to the object, for which there is no resident
page. If the page corresponding to a block is already resident and
valid, the block can simply be discarded.
The existing implementation tries to minimize the number of I/Os used.
For each cluster of swap blocks, it finds maximal runs of valid swap
blocks not resident in memory, and valid resident pages. During this
processing, the object lock may be dropped in several places: when
calling getpages, or when blocking on a busy page in
vm_page_grab_pages(). While the lock is dropped, another thread may
free swap blocks, causing getpages to page in stale data.
Fix the problem following a suggestion from Jeff: use getpages'
readahead capability to perform clustering rather than doing it
ourselves. The simplies the code a bit without reintroducing the old
behaviour of performing one I/O per page.

Revert parts of r353274 replacing vnet_state with a shutdown flag.
Not having the state flag for the current SI_SUB_* makes it harder to debug
kernel or module panics related to VNET bringup or teardown.
Not having the state also does not allow us to check for other dependency
levels between components, e.g. for moving interfaces.
