a638dc4ebc vfs: Add ioflag to VOP_DEALLOCATE(9)
The addition of ioflag allows callers passing
IO_SYNC/IO_DATASYNC/IO_DIRECT down to the file system implementation.
The vop_stddeallocate fallback implementation is updated to pass the
ioflag to the file system implementation. vn_deallocate(9) internally is
also changed to pass ioflag to the VOP_DEALLOCATE call.

ce92f5a91b wpa: Add wpa_cli action file event
Yan Zhong at FreeBSD Foundation is working on a wireless network
configuratior for an experimental FreeBSD installer. The new installer
requires an event to detect when connecting to a network fails due to a
bad password. When this happens a WPA-EVENT-TEMP-DISABLED event is
triggered. This patch passes the event to an action file provided by
the new experimental installer.

5e4279a8f3 loader: fix multiboot loading on UEFI
The Xen kernel has no symbol tables, so calling lookup_symbol against
it triggers the following Divide by Zero fault:

/boot/xen data=0x2809c8+0x149638 |
!!!! X64 Exception Type - 00(#DE - Divide Error)  CPU Apic ID - 00000000 !!!!

Fix lookup_symbol to prevent the #DE fault from happening if the
symbol table is not loaded and also fix loadfile_raw to mark multiboot
kernels as relocatable, since the only multiboot kernel supported is
Xen and was already unconditionally booted as relocatable.

3ad1e1c1ce nfscl: Add a Lookup+Open RPC for NFSv4.1/4.2
This patch adds a Lookup+Open compound RPC to the NFSv4.1/4.2
NFS client, which can be used by nfs_lookup() so that a
subsequent Open RPC is not required.
It uses the cn_flags OPENREAD, OPENWRITE added by commit c18c74a87c.
This reduced the number of RPCs by about 15% for a kernel
build over NFS.

For now, use of Lookup+Open is only done when the "oneopenown"
mount option is used.  It may be possible for Lookup+Open to
be used for non-oneopenown NFSv4.1/4.2 mounts, but that will
require extensive further testing to determine if it works.

While here, I've added the changes to the nfscommon module
that are needed to implement the Deallocate NFSv4.2 operation.
This avoids needing another cycle of changes to the internal
KAPI between the NFS modules.

This commit has changed the internal KAPI between the NFS
modules and, as such, all need to be rebuilt from sources.
I have not bumped __FreeBSD_version, since it was bumped a
few days ago.

97cbd5e722 loader: open file list should be dynamic
Summary:
Open file list is currently created as statically allocated array (64 items).
Once this array is filled up, loader will not be able to operate with files.
In most cases, this mechanism is good enough, but the problem appears, when
we have many disks with zfs pool(s). In current loader implementation, all
discovered zfs pool configurations are kept in memory and disk devices open -
consuming the open file array. Rewrite the open file mechanism to use
dynamically allocated list.

That commit moved key generation into a child process, including
a memory allocation referenced by a structure.  The child wrote
the structure to the parent over a pipe, but did not write the
referenced allocation.  The parent read the structure from the
child and used its pointer, which was bogus in the parent.

In the child, send both chunks of data to the parent.  In the
parent, make a corresponding allocation and read both chunks.
