ddb: allow specifying the exact address of the symtab and strtab
When the FreeBSD kernel is loaded from Xen the symtab and strtab are
not loaded the same way as the native boot loader. This patch adds
three new global variables to ddb that can be used to specify the
exact position and size of those tables, so they can be directly used
as parameters to db_add_symbol_table. A new helper is introduced, so callers
that used to set ksym_start and ksym_end can use this helper to set the new
variables.
It also adds support for loading them from the Xen PVH port, that was
previously missing those tables.

ddb/db_main.c:
- Add three new global variables: ksymtab, kstrtab, ksymtab_size that
can be used to specify the position and size of the symtab and
strtab.
- Use those new variables in db_init in order to call db_add_symbol_table.
- Move the logic in db_init to db_fetch_symtab in order to set ksymtab,
kstrtab, ksymtab_size from ksym_start and ksym_end.
ddb/ddb.h:
- Add prototype for db_fetch_ksymtab.
- Declate the extern variables ksymtab, kstrtab and ksymtab_size.
x86/xen/pv.c:
- Add support for finding the symtab and strtab when booted as a Xen
PVH guest. Since Xen loads the symtab and strtab as NetBSD expects
to find them we have to adapt and use the same method.

Finish QCOW version 2 and stop making it conditional.
We have a different ordering for the RC block(s) and L2 tables.
This is expected to be a non-issue, because everything is found
through file offsets in the corresponding RC table and L1 table.
Files that grow organically have RC blocks and L2 tables scattered
all over the place anyway.
The reason for the difference is that mkimg needs to be able to
write to a pipe. We can't seek forward and backward to fill in
the bits in non-sequential order.
Expect ELOOP on Darwin/Linux with "O_NOFOLLOW was specified and the target is a
symbolic link" case. Assume EMLINK on the rest of the OSes (FreeBSD, Solaris,
etc)
Fix the creation of the L2 cluster table for version 1. The blkofs
variable was assigned the image offset in bytes and not in blocks
(i.e. sectors). This had image_data() return FALSE, which meant that
we didn't assign a cluster when we needed and also meant that we
didn't write parts of the L2 table when we should have. The result
being that the actual data clusters were written at the wrong offset.
Improve support for QCOW version 2. We're having the right layout
and even know how many refcnt blocks we need. All we need to do is
populate the refcnt blocks for every cluster we write and allocate
a cluster when we need a new refcnt block. The allocation part is
tricky in that it'll interleave with the assignment of clusters to
L2 tables and data. Since version 2 is not quite done, keep it
compiled out for now.

vm_map_pmap_enter() and pmap_enter_object() are currently not aware of
the wired attribute of the mapping. As result, some pmap
implementations clear the wired state of the page table entries, which
breaks invariants and allows the entries to be lost. Avoid calling
vm_map_pmap_enter() for the MADV_WILLNEED on the wired entry, the
pages must be already mapped.

As per [1] Intel only supports this driver on 64bit platforms.
For now restrict it to amd64. Other architectures might be
re-added later once tested.
Remove the drivers from the global NOTES and files files and move
them to the amd64 specifics.
Remove the drivers from the i386 modules build and only leave the
amd64 version.
Rather than depending on "inet" depend on "pci" and make sure that
ixl(4) and ixlv(4) can be compiled independently [2]. This also
allows the drivers to build properly on IPv4-only or IPv6-only
kernels.
Correct display of bhyve SMBIOS UUIDs with dmidecode by bumping the version.
The mixed little/big-endianness of SMBIOS UUIDs was clarified in v2.6

bhyve's SMBIOS reported as 2.4 though it implemented the 2.6-style of
memory layout. This resulted in dmidecode reporting a different
UUID than one passed in via the -U option.

Rename the tests to something more meaningful. I spent way too long
trying to get the test name right, failed, gave up and used a sequence
number instead. When I realized it wasn't because of the number of
underscores in the name that I really started to think. I didn't have
braces around the variable names ...
Thus: test_1 is now called apm_1x1_512_qcow, which gives you all you
need to run mkimg by hand.
Don't update the baseline file when the result of the test is identical
to the baseline. Since we don't run gzip with the -n option, the output
of gzip varies for identical result files if and when they are created
at different time. Ouch...
Rather than add -n and commit a 600K+ diff for the changes to all the .uu
files, it's less of a churn to uudecode and gunzip the baseline file and
compare that to the new result file to determine if the baseline file
needs to be updated.
This way, "atf-sh mkimg.sh rebase" can be run as many times as people like
and a subsequent "svn status" will not show unnecessary diffs.

Add support for QCOW version 1. Version 2 is partially implemented.
And because of that, it's entirely disabled for now. Both versions
are similar enough that a single header definition works for both
of them. The only "diverting" side-effect is that the union of the
two is larger than the official V1 header.
What this means for our V1 support is that we can't put the L1 table
adjacent to the V1 header (i.e. at offset 0x30 in the file), unless
we revert to hackery and klugery. Let's not. Instead, we align the L1
table at the cluster boundary. This is in line with the V2 layout and
perfectly ok for V1 anyway (ok -- as far as I've seen so far).
Due to the alignment, our V1 image seems to be 1 cluster larger than
the V1 image created by qemu-img (on average).
Compression of the clusters is not supported at this time.

The new naming scheme for keymap files for use with vt(4) introduced a
collision for "no" as a country code with "NO" meaning "do not load any
keymap" (which also has been the default value in etc/defaults/rc.conf
for a long time).
The result of this collision is, that "kbdcontrol -l no" will load the
Norwegian keymap, while "keymap=no" in rc.conf was interpreted as the
lower case spelling of "NO" meaning "no keyboard" (and "no.kbd" was not
loaded).
Fix this by matching only the upper-case spelling "NO" in rc.d/syscons
when deciding whether to load a keymap file.
This will lead to "no.kbd" being loaded, if the until now valid (but
non-default) spelling "no" was used in an individual rc.conf file to mean
"no keyboard". But all alternatives I could think of introduce a larger
violation of POLA ...

Improve transmit sending offload, TSO, algorithm in general.
The current TSO limitation feature only takes the total number of
bytes in an mbuf chain into account and does not limit by the number
of mbufs in a chain. Some kinds of hardware is limited by two
factors. One is the fragment length and the second is the fragment
count. Both of these limits need to be taken into account when doing
TSO. Else some kinds of hardware might have to drop completely valid
mbuf chains because they cannot loaded into the given hardware's DMA
engine. The new way of doing TSO limitation has been made backwards
compatible as input from other FreeBSD developers and will use
defaults for values not set.
