MFC r261535:
Add support for MegaRAID Fury cards. The main change needed to boot from a
9341-4i controller was to ensure that scatter/gather lists are ended with
an end-of-list marker. Both the mrsas and Linux megaraid_sas drivers use
this marker with Invader cards as well, so we do the same thing, though
it is apparently not strictly necessary.

MFC r262020:

Make it possible to use the env kernel config file option for AVILA
and CAMBRIA boards that does not use loader to load the kernel. This
is basically how it was done for i386. This way tunables can also be
set. For example in config file:

env "/conf/AVILA.env"

And in AVILA.env:

vfs.unmapped_buf_allowed=0

Import libucl into head

UCL is heavily infused by nginx configuration as the example of a convenient
configuration system. However, UCL is fully compatible with JSON format and is
able to parse json files.

UCL is used by pkg(8) for its configuration file as well for the manifest format
in packages, it will be used in base for the pkg boostrap (signature checking
and configuration file parsing.)

libucl has been developped and is maintained by vsevolod@

Sync pkg(7) with head
MFC 261243:
Some BIOSes incorrectly use standard memory resource ranges to list
the memory ranges that they decode for downstream devices rather than
creating ResourceProducer range resource entries.  The result is that
we allocate the full range to the PCI root bridge device causing
allocations in child devices to all fail.

As a workaround, ignore any standard memory resources on a PCI root
bridge device.  It is normal for a PCI root bridge to allocate an I/O
resource for the I/O ports used for PCI config access, but I have not
seen any PCI root bridges that legitimately allocate a memory resource.

Merge r261882, r261898, r261937, r262760, r262799:
  Once pf became not covered by a single mutex, many counters in it became
  race prone. Some just gather statistics, but some are later used in
  different calculations.

  A real problem was the race provoked underflow of the states_cur counter
  on a rule. Once it goes below zero, it wraps to UINT32_MAX. Later this
  value is used in pf_state_expires() and any state created by this rule
  is immediately expired.

  Thus, make fields states_cur, states_tot and src_nodes of struct
  pf_rule be counter(9)s.
