jevents includes a very permissive json parser that accepts invalid
json, of which there are many examples in libpmc (typically extra or
missing commas). Convert the arm64 files to proper json so other tools
can parse them.

Instead of first detaching the children(s) and then delete them,

These are insignificant as far as declarations go, and we've historically
allowed it. fhlinkat in ^/sys/kern/syscalls.master, for example, currently
has a trailing comma after its final argument that this version of
makesyscalls is ignoring (not by conscious decision).
Fix it for now by actively stripping off trailing whitespace/commas until
we decide to actively prohibit it.
The driver used to always add the mmc device as it's child even
it no card was detected. Add a function that will detect if the
card is present or not and that will attach/detach the mmc device.
The function is either call on attach (as we won't have the interrupt
fired) or from two taskqueues. The first taskqueue will directly call
the function when the sdcard was present and is now removed and the other
one will delay a bit the attach when we didn't had a card and now have one.
This is mostly based on comments from the sdhci driver where it describe
a situation when the CD pin is detected before the others pins are connected.

This method will disable the regulators, clocks and assert the reset of
the module. It will also detach it's children (the mmc device) and release
it's resources.
While here enable the regulators on attach as we need them to power up
the sdcard or emmc.

Those clocks are always enable by default and are not really explained
in the TRM but the reason we had them is that they have the periph clock
as a parent and those parent should never be disable which can happen
if we disable all the childs. The current childs are the sd/emmc/sdio clocks
so the board will hang if we disable them.

This is both reasonable and a common GNUism that a lot of ported software
expects.
Universally process \r, \n, and \t into carriage return, newline, and tab
respectively. Newline still doesn't function in contexts where it can't
(e.g. BRE), but we process it anyways rather than passing
UB \n (escaped ordinary) through to the underlying regex engine.
Adding a --posix flag to disable these was considered, but sed.1 already
declares this version of sed a super-set of POSIX specification and this
behavior is the most likely expected when one attempts to use one of these
escape sequences in pattern space.
This differs from pre-r197362 behavior in that we now honor the three
arguably most common escape sequences used with sed(1) and we do so outside
of character classes, too.
Other escape sequences, like \s and \S, will come later when GNU extensions
are added to libregex; sed will likely link against libregex by default,
since the GNU extensions tend to be fairly un-intrusive.

This is a 32-bit structure embedded in each vm_page, consisting mostly
of page queue state. The use of a structure makes it easy to store a
snapshot of a page's queue state in a stack variable and use cmpset
loops to update that state without requiring the page lock.
This change merely adds the structure and updates references to atomic
state fields. No functional change intended.
