4257a5292a upas/marshal: add -S saveto to save outgoing mail, fix -F
Upas/marshal -F was broken with the '-8' command, and silly
without it: It used aliases passed on the command line, so
the destination address was ignored with -8 was passed.

In addition, it would create a new mailbox for any aliases
being sent to, instead of putting them all in one location.

The new -S option is similar to -F, but specifies where the
message should go.

6cc223ee56 pc/pc64: fix faulty mtrr slot reuse (thanks Fulton)
The change 3306:c5cf77167bfe made the code reuse MTRR slots
of the default memory type.

But this did not take overlapping ranges into account!

If two or more variable-range MTRRs overlap, the following rules apply:

a.	If the memory types are identical, then that memory type is used.
b.	If at least one of the memory types is UC, then UC memory type is used.
c.	If at least of of the memory types is WT. and the only other memory type
	is WB, then th WT memory type is used.
d.	If the combination of memory types is not listed above,
	then the memory type used in undefined.

It so happend that on a Dell Latitude E7450 that the BIOS defines
the default type as UC. and the first slot defines a 16GB range
of type WB. Then the rest of the ranges mark the PCI space back
as UC, but overlapping the first WB range! This works because
of rule (B) above.

When trying to make the framebuffer write-combining, we would
falsely reuse one of the UC sub-ranges and making the UC memory
into WB as a side effect.

Thanks to Fulton for his patience and providing debug logs and
doing experiments for us to narrow the problem down.

0ba91ae22a pc, pc64: allocate i/o port space for unassigned pci bars, move ioalloc() to port/iomap.c
With some newer UEFI firmware, not all pci bars get
programmed and we have to assign them ourselfs.

This was already done for memory bars. This change
adds the same for i/o port space, by providing a
ioreservewin() function which can be used to allocate
port space within the parent pci-pci bridge window.

Also, the pci code now allocates the pci config
space i/o ports 0xCF8/0xCFC so userspace needs to
use devpnp to access pci config space now. (see
latest realemu change).

Also, this moves the ioalloc()/iofree() code out
of devarch into port/iomap.c as it can be shared
with the ppc mtx kernel.

97de3f67c2 upas/common: delete library on 'mk clean'
libcommon.a$O doesn't end with a .a, so mk
doesn't know how to look inside it in order
to check if the files are up to date.

This means that when 'mk clean' is run,
libcommon.a$O looks up to date:

	% mk clean
	...
	% mk
	mk: 'default' is up to date

Deleting the library works around this problem.

33fb16c9fe profile: don't create $wsys if it doesn't exist
When $wsys doesn't exist (eg, drawterm -G, or
rcpu from a text console), the profile would
create an empty $wsys variable, and sessions
started in this environment would fail with a
null list in concatenation.

This change tests if /mnt/term/env/wsys exists
before assigning it.

a4c6dc1d3d aux/realemu: use #$/pci/B.D.Fraw to access pci config space
This prevents VESA bios from accessing the pci
CONFIG_ADDRESS/CONFIG_DATA registers (0xCF8/0xCFC)
directly to access pci config space.

This makes sure the access to pci config space is
properly serialized by the kernel.

b5086c1863 libc: recurse on smaller half of array
Our qsort has an optimization to recurse on one
half of the array, and do a tail call on the other
half. Unfortunately, the condition deciding which
half of the array to recurse on was wrong, so we
were recursing on the larger half of the array and
iterating on the smaller half.

This meant that if we picked the partition poorly,
we were pessimizing our stack usage instead of
optimizing it.

This change reduces our stack usage from O(n)
to O(log(n)) for poorly chosen pivots.

0205392410 audiohda: make it work with qemu (thanks mischief)
the driver was not using irb interrupts
and was just polling the irb write pointer
to wait for command completion.

this is not supported by qemu.

qemu requires the use of irb interrupt handshake
and it refuses to accept the next command until we
acknowledge the irb interrupt.

950d970671 ip/tinc: fix reportedge()
supplying a non-ip address in ADD_EDGE crashes the unix tincd.

the reason was that we where misreporting ADD_EDGE messages;
ignoring the information from our peers; and always supplying
the Address string from our configuration instead of the
connections ip address.

now we just report the edge information as is.

a5764f8181 pc, pc64: remove mystery "type" bits in pcicfgrw*raw() (fixes qemu, thanks mischief)
the access functions for pci config space in config mode #1
used to set bit 0 in the register offset if the access was
to a device on any bus different from 0.

it is completely unclear why this was done and i can't find
any documentation on this.

but for sure, this breaks all pci config spacess access to
pci devices behind a bridge on qemu. with -trace pci* it
was discovered that all config space register offsets on
devies behind pci brige where off by one.

on real hardware, setting bit 0 in the offset doesnt appear
to be an issue.

thanks mischief for reporting and providing a qemu demo
configuration to reproduce the problem.

ori and echoline are reporting regression on some 6000 cards;

cf8ff0e713 sdnvme: handle machines with more cpu's than submit queues (thanks mischief)
We used to assume a 1:1 pairing of processors to submit queues.
With recent machines, we now got more cpu cores than what some
nvme drives support so we need to distribute the queues across
these cpu's which requires locking on command submission.

There is a feature get/set command to probe the number of submit
and completion queues, but we decided to just handling
submission queue create command error gracefully as it is simpler
and has less chance of regression with existing setups.

Thanks to mischief for investigating and writing the code.

bf18724738 ndb/dns: mark ns record authoritative when in our area for delegation
I have the problem that i need to delegate a subdomain
to another name server that is confused about its own zone
(and its own name) returning unusable ns records.

With this, one can make up a nameserver entry in ndb that
is authoritative and owned by us for that nameserver,
and then put it in the soa=delegated ns entry.

This promotes the ns record in the soa=delegated to
Authoritative, which avoids overriding the ns rr's from
the confused server for the delegated zone.
