linker_unload_file() rather than kern_kldload() and kern_kldunload(). This
ensures that the handlers are invoked for files that are loaded/unloaded
automatically as dependencies. Previously, they were only invoked for files
loaded by a user.
As a side effect, the kld_load and kld_unload handlers are now invoked with
the kernel linker lock exclusively held.

This should not happen and just indicates some configuration error which

rm: /tmp/bsdinstall_etc/fstab: No such file or directory
The two lines are unrelated, and the rm is spurious. Let's add `-f' to
that rm(1) so it doesn't confuse us when debugging an install.

instead of peeking inside in-kernel radix via kget.
This permits us to change kernel structures without breaking userland.
Additionally, this change provide more reliable and faster output.
`Refs` and `Use` fields available in IPv4 by default (and via -W
for other families) were removed. `Refs` is radix-specific thing
which is not informative for users. `Use` field value is handy sometimes,
but a) current API does not support it and b) I'm not sure we will
support per-rte pcpu counters in near future.
Old method of retrieving data is still supported (either by defining
NewTree=0 or running netstat with -A). However, Refs/Use fields are
hidden.

code more naive and robust:
1. When setting ev_value, also always set ev_flags appropriately
2. Always check ev_value and ev_flags before calling free.
Both the value and the EV_DYNAMIC property can come directly from the
consumers of the environment functionality, so it's good to be careful.
And since this code is typically not looked at for long periods of
time, it's good to have it be a little "dumb-looking".
Trigger case for the bug:
env_setenv("foo", 0, "1", NULL, NULL);
env_setenv("foo", 0, "2", NULL, NULL);

GCC 4.2 and previous have always warned about
"No newline at end of file".
Upstream GCC removed the warning completely but
Apple made it an optional warning. Adopt it for
compatibility with older GCC and clang.

- Use make_dev_p() in tty_makedevf() instead of make_dev_cred().
- Always pass MAKEDEV_CHECKNAME flag.
- Optionally pass MAKEDEV_REF flag.
- Provide macro for compatibility with old API.
This fixes races with simultaneous creation and desctruction of
ttys, and makes it possible to call tty_makedevf() from device
cloners.
A race in tty_watermarks() still exist, since the latter drops
lock for M_WAITOK allocation. This will be addressed in separate
commit.

child process that were inherited from its parent. However, this should
not be done in the case of a vfork, since the fork handler ends up removing
the tracepoints from the shared vm space, and userland DTrace probes in the
parent will no longer fire as a result.
Now the child of a vfork may trigger userland DTrace probes enabled in its
parent, so modify the fasttrap probe handler to handle this case and handle
the child process in the same way that it would handle the traced process.
In particular, if once traces function foo() in a process that vforks, and
the child calls foo(), fasttrap will treat this call as having come from the
parent. This is the behaviour of the upstream code.
While here, add #ifdef guards to some code that isn't present upstream.
