sys: Drop redundant NULL check before m_freem(9)

m_freem(9) safely has accepted NULL argument at least since 4.2BSD:
https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/sys/uipc_mbuf.c

Compile-tested on amd64/ALL.

Suggested by knakahara@

btuart(4): Convert to ttylock/ttyunlock.

remove KASSERT() checking for t_oproc at open since assigning this line
discipline to a pty may not have that set. Instead do a runtime check to
ensure that the function exists before calling it, as ttstart() handles it.

Same code in btuart.c, bcsp.c and bth5.c

Add comments about D_MPSAFE to functions called as struct linesw.l_ioctl.

update from HEAD

At suggestion of chuq@, modify config_attach_pseudo() to return with a
reference held on the device.

Adapt callers to expect the reference to exist, and to ensure that the
reference is released.

include "ioconf.h" to get the 'void <driver>attach(int count);' prototype.

Rebase to HEAD as of a few days ago.

Rebase.

netbt: rename some attach/detach functions to have _pcb suffix, so
we could use standard attach/detach naming for pr_usrreq functions.
No functional change.

Put back #include "ioconf.h" per popular demand.

Introduce actions/requests to handle authorization for ppp(4), sl(4),
strip(4), btuart(4) and bcsp(4) network interfaces and devices.

Authorizing actions from the generic scope using a device scope wrapper
is a big no-no.

As painful as it is, use kauth_authorize_generic() for now.

some changes to serial bluetooth host controller interfaces

btuartd(8) should be named btattach(8) for consistency
with other parts of NetBSD

make btattach(8) a single-use tool for less complexity

device specicific initialisation (from btuart(4)) is carried
out prior to activating the line discipline (in btattach(8)),
which simplifies the API somewhat and means that the user
tool and the kernel do not need to be kept in sync.

btuart(4) driver is much reduced; naming is made consistent
and all tsleep() and delay() are removed to userland

Clean up the way that bluetooth drivers attach to the bluetooth stack,
to remove the frobbing that drivers must do in the hci_unit structure.

- driver provides a static const interface descriptor
- hci_unit is allocated by hci_attach() rather than part of softc
- statistics are compiled by driver and provided on request
- driver provides output methods and is responsible for output queue
- stack provides input methods and is responsible for input queue
- mutex is used to arbitrate device queue access

convert device printf() usages to aprint_xxxx()

use more device_t and device_xxx() accessors

make bluetooth stack keep device_t instead of softc pointer as
device is not necessarily part of softc, and pass device_t to
driver callbacks. hci_devname is no longer required.

Call ttyflush() with tty_lock held.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.
