to double check for if the card has probed before. In fact, there's no
reason to single check either. Simplify the code as a result.
$FreeBSD$ added to lxutil.c in a non-standard way to help keep the
diffs with upstream to a minimum.

CloudABI has two separate kernel modules: cloudabi and cloudabi64. The
first module contains all the pointer size independent code, whereas
cloudabi64 contains the actual 64-bits specific system calls and the ELF
loader.

Now each subcommands checks its arguments in a dedicated functions.
This helps improving input validation, code readability/maintainability
While here:
- Add a -y option to pw userdel/usermod so it can maintain NIS servers if
nispasswd is not defined in pw.conf(5)
- Allow pw -r <rootdir> to remove directory with userdel -r
- Fix bug when renaming a user which was not renaming the user name it groups
it is a member of.
- Only parse pw.conf(5) when needed.
o remove disabled code;
o if nexthop address is link-local, use embedded scope zone id to
determine outgoing interface;
o properly fill ro_dst before doing route lookup;
o remove LLE lookup, instead check rt_flags for RTF_GATEWAY bit.

First they are redundant with the tests we currently have on pw(8)
Second they to modify the host database instead of being self contained withing
the test directory
- Rather than assuming that a process is listening on 127.0.0.1:22, use
nc(1) to find an available port and bind to it for the duration of the
test.

doubt most people will read to the end... Note the use of sys/cdefs.h
for pre-C11 compilers...
I didn't included a note about being compatibile w/ userland since a
C11 feature should be obviously usable in userland...

When a process is exiting, there is a narrow window where p_cred may be
NULL while its threads are still executing. Specifically, the last thread
to exit a process sets the process state to PRS_ZOMBIE with the proc
spinlock held and then calls thread_exit(). thread_exit() drops the spin
lock, permitting the process to be reaped and thus causing its cred struct
to be released. However, the exiting thread may still cause DTrace probes
to fire by calling sched_throw(), resulting in a double fault if such a
probe enabling attempts to access the GID or UID DIF variables.
The thread's cred reference is not susceptible to this race since it is not
released until after the thread has exited.

This field is only used in a KASSERT that verifies that no locks are held
when returning to user mode. Moreover, the td_locks accounting is only
correct when LOCK_DEBUG > 0, which is implied by INVARIANTS.

Some of FDT blobs for AM335x-based devices use pinmux pullup/pulldown
flag to setup initial GPIO ouputp value, e.g. 4DCAPE-43 sets LCD DATAEN
signal this way. It works for Linux because Linux driver does not enforce
pin direction until after it's requested by consumer. So input with pullup
flag set acts as output with GPIO_HIGH value

Summary:
Use the newly created `kern_shm_open()` function to create objects with
just the rights that are actually needed.

This allows you to specify the capabilities that the new file descriptor
should have. This allows us to create shared memory objects that only
have the rights we're interested in.
The idea behind restricting the rights is that it makes it a lot easier
for CloudABI to get consistent behaviour across different operating
systems. We only need to make sure that a shared memory implementation
consistently implements the operations that are whitelisted.

The first one never triggers because bpf_canfreebuf() can only be true for
zero-copy buffers and zero-copy buffers are not read with read(2).
The second also never triggers, because we check the free buffer before
calling ROTATE_BUFFERS(). If the hold buffer is in use the free buffer
will be NULL and there is nothing else to do besides drop the packet. If
the free buffer isn't NULL the hold buffer _is_ free and it is safe to
rotate the buffers.
Update the comment in ROTATE_BUFFERS macro to match the logic described
here.
While here fix a few typos in comments.
