Replace all uses of kern_mmap with kern_mmap_req move the old kern_mmap.
Reand rename kern_mmap_req to kern_mmap .
The helper saved some code churn initially, but having multiple
interfaces is sub-optimal.

nids(4) was a clever idea in the early 2000's when the market was
flooded with 10/100 NICs with Windows-only drivers, but that hasn't been
the case for ages and the driver has had no meaningful maintenance in
ages. It only supports Windows-XP era drivers.
Also remove:
- ndis support from wpa_supplicant
- ndiscvt(8)

When diff hits certain access errors, function diffreg() shows the error
message, and then returns to the calling function, which calls
print_status() with the return value.
However, in these cases, the return value isn't changed from the initial
default value of D_SAME.
Normally, print_status() with a value of D_SAME does nothing, so this
works out ok, however, if the "-s" flag is set, a message is displayed
showing identicality:
case D_SAME:
if (sflag)
printf("Files %s%s and %s%s are identical\n", path1, entry, path2, entry);
break;
This then produces such results as:
% diff -s /COPYRIGHT /var/run/rpcbind.sock
diff: /var/run/rpcbind.sock: Operation not supported
Files /COPYRIGHT and /var/run/rpcbind.sock are identical
% diff -s /COPYRIGHT /etc/master.passwd
diff: /etc/master.passwd: Permission denied
Files /COPYRIGHT and /etc/master.passwd are identical
Create a D_ERROR status which is returned in such cases, and
print_status() then deals with that status seperately from D_SAME

This is unnecessary when cross-building from Linux/macOS.
Additionally, cp -p appears to be broken on macOS Big Sur
(https://openradar.appspot.com/8957219).
For some unknown reason this commit appears to fix
freezes when building on macOS Big Sur.
This also fixes building in docker with volume mounts
with ACLs, since setting the ACL with cp -p fails otherwise.

We provide these for compat with other queue.h headers since some software
assumes it exists (e.g. the libevent contrib code), but we are not
encouraging their use (NULL should be used instead).
This fixes the following warning (which should arguable be an error since
it results in a function call to an undefined function):

These tests are basic fuzz tests that permute input to trigger crashes
rather than regression or unit tests. Additionally, some of them take a
rather long time to run and should probably be run on a dedicated fuzzing
job instead. Moreover, these simple tests use rand() instead of a real
fuzzing tool that generates interesting inputs (e.g. LLVM libFuzzer) so are
unlikely to find anything interesting when run in CI.
This allows removing one BROKEN_TESTS case due to timeouts and speeds up
running tests on emulated platforms such as QEMU.

The NS_MOREFRAG flag can be set in a netmap slot to represent a
multi-fragment packet. Only the last fragment of a packet does
not have the flag set. On TX rings, the flag may be set by the
userspace application. The kernel will look at the flag and use it
to properly set up the NIC TX descriptors.
On RX rings, the kernel may set the flag if the packet received
was split across multiple netmap buffers. The userspace application
should look at the flag to know when the packet is complete.

lualoader was previously not processing \ as escapes; this commit fixes
that and does better error checking on the value as well.
Additionally, loader.conf had some odd restrictions on values that make
little sense. Previously, lines like:
kernel=foo
Would simply be discarded with a malformed line complaint you might not
see unless you disable beastie.
lualoader tries to process these as well as it can and manipulates the
environment, while forthloader did minimal processing and constructed a
`set` command to do the heavy lifting instead. The lua approach was
re-envisioned from building a `set` command so that we can appropriately
reset the environment when, for example, boot environments change.
Lift the previous restrictions to allow unquoted values on the right hand
side of an expression. Note that an unquoted value is effectively:
[A-Za-z0-9-][A-Za-z0-9-_.]*
This commit also stops trying to weirdly limit what it can handle in a
quoted value. Previously it only allowed spaces, alphanumeric, and
punctuation, which is kind of weird. Change it here to grab as much as it
can between two sets of quotes, then let processEnvVar() do the needful and
complain if it finds something malformed looking.
My extremely sophisticated test suite is as follows:
<<EOF
X_01_simple_string="simple"
X_02_escaped_string="s\imple"

Future work may provide a stub loader module in userland so that we can
formally test the loader scripts rather than sketchy setups like the above
in conjunction with the lua-* tools in ^/tools/boot.

Older glibc headers did some very nasty things that have since been
sanitised. We could also fix this by adding a linux/getopt.h wrapper
alongside the existing common/getopt.h that #undef's __need_getopt, but
that seems a little more hacky and complicated.
