new-bus: Disable assertions for rman mismatches for activate/deactivate
Bus drivers which use an rman to sub-divide a resource allocated from
a parent bus should handle mapping requests (and activate/deactivate
requests) for those sub-allocated resources by doing a subset mapping
of the resource allocated from the parent (and then using this to
handle activate/deactivate requests).
However, not all bus drivers which use internal rmans (such as acpi(4)
and pci_pci(4)) do that since not all nexus drivers support
bus_map/unmap. Eventually bus drivers should be updated to do this
properly at which point these assertions can be reenabled.

vt(4): Always call vt_window_switch() in vtterm_cnungrab()
[Why]
This ensures that vtterm_cnungrab() is the mirror of vtterm_cngrab().
And the latter always call vt_window_switch() and thus the backend's
vd_postswitch().
This makes sure that whatever the backend did during vtterm_cngrab(), it
can undo it during vtterm_cnungrab().

vt(4): New bitblt_text variant making a copy before unlocking vt_buf
[Why]
In the DRM drivers and the integration with vt(4), we need to execute
DRM code outside of the vtbuf_lock. The reason is that this DRM code
acquires locks which can't be acquired when vtbuf_lock, an MTX_SPIN
mutex, is already held.
[How]
A vt(4) backend can now set the `vd_bitblt_after_vtbuf_unlock` flag to
true if it wants to be called outside of vt_buf_lock.
In this case, vt(4) uses an internal version of bitblt_text that uses
the `vd_drawn` arrays, plus a new `vd_pos_to_flush` array, to track
characters to draw/refresh. This internal version then uses the
backend's bitblt_bmp callback to draw the characters after vt_buf has
been unlocked.
Drawing borders and CPU logos is also deferred after the vt_buf lock is
released for the same reason.
We introduce another lock (a default mutex), only used when the
`vd_bitblt_after_vtbuf_unlock` flag is set, to replace part the role of
the vt_buf lock and manage concurrent calls to vt_flush().
The `SC_NO_CONSDRAWN` define is dropped because we now always need the
`vd_drawn` arrays.

Differential Revision: https://reviews.freebsd.org/D42057
[Why]
The same protection was added to vt_flush() in the previous commit. We
want the same one in vt_window_switch(): if e.g. the DRM driver panics
while handling a call to vt_window_switch(), we don't want to
recursively call vt_window_switch() again and trigger another panic.

[Why]
If there is a problem with DRM drivers or in their integration with
vt(4) and displaying something on the console triggers a panic, there is
a high chance that displaying that panic will trigger another one,
recursively.
[How]
If vt_flush() is called and it detects is is called resursively from
another panic, it return immediately, doing nothing, to avoid the risk
of triggering another panic.
Reviewed by: manu

Differential Revision: https://reviews.freebsd.org/D42056
[Why]
The reason is that in some places in the DRM drivers (in particular, the
framebuffer management code), kmalloc() is called from a non-sleepable
context, such as after a call to mtx_lock(8) with an MTX_DEF mutex.
If `GFP_KERNEL` is defined as `M_WAITOK`, we hit an assertion from
witness(4).
[How]
The definition of `GFP_KERNEL` is changed to `M_NOWAIT`. This means that
callers should verify the return value of kmalloc(). Fortunately, this
is always the case in Linux.

newbus: Add a set of bus resource helpers for nexus-like devices
These routines can be used to implement
bus_alloc/adjust/activate/deactive/release_resource on bus drivers
which suballocate resources from rman(9) resource managers.
These methods require a new bus_get_rman method in the bus driver to
return the suitable rman for a given resource type. The
activate/deactivate helpers also require the bus to implement the
bus_map/ummap_resource methods.
kqueue: on process exit, force-clear its registered signal events
Normally, process already has all its kqueue fds destroyed at the moment
p_klist is detached in exit flow. But, if the process was created with
rfork(2) with shared file descriptors, its signal knotes can survive.
Then, knlist_detach() does not destroy non-empty knlist. Later, when
owning kqueue is closed, we access freed (or rather, reused, because
struct proc is type-stable) memory by referencing p->p_klist from such
knote.
Handle this situation by deleting all knotes hanging from p_klist.
