No need for probe messages when a TxQ is too full for a post to be done.
Existing drivers check if there is room in the queue before posting
descriptors, even though efx_tx_qdesc_post() does the check itself.
The new SFN Windows driver doesn't perform the check before calling
efx_tx_qdesc_post(), but that means these probes can get frequently
printed out. It's normal driver behaviour so there's no need to print
an error.

Rename MCDI monitors to be consistent with YML.

For non-ERMS case the code used handle possible trailing bytes with
movsb first and then followed it up with movsq. This also happened
to alter how calculations were done for other cases.
Handle the tail with regular movs, just like when copying forward.
Use leaq to calculate the right offset from the get go, instead of
doing separate add and sub.
This adjusts the offset for non-rep cases so that they can be used
to handle the tail.
The routine is still a work in progress.

Given a zeroed struct image_args with an allocated buf member,
exec_args_add_fname() must be called to install a file name (or NULL).
Then zero or more calls to exec_args_add_env() followed by zero or
more calls to exec_args_add_env(). exec_args_adjust_args() may be
called after args and/or env to allow an interpreter to be prepended to
the argument list.
To allow code reuse when adding arg and env variables, begin_envv
should be accessed with the accessor exec_args_get_begin_envv()
which handles the case when no environment entries have been added.
Use these functions to simplify exec_copyin_args() and
freebsd32_exec_copyin_args().

It is possible that we started with a relative path but during the
lookup, found an absolute symlink. In this case, BENEATH handling
code needs the latch, but it is too late to calculate it.
While there, somewhat improve the assertions. Clear the NI_LCF_LATCH
flag when the latch vnode is released, so that asserts know the state.
Assert that there is a latch if we entered beneath+abs path mode,
after the starting point is processed.

While here when setting the clock to the assigned freqeuncy, allow the clock
driver to round down or up the frequency as sometimes the exact frequency cannot
be obtain.
We can no longer use sizeof() to get the path buffer's size. Apply
a straightforward fix for now with the aim of MFCing soon.

Otherwise the free page count will not accurately reflect the physical
page allocator's state. On 11 this can trigger panics in
vm_page_alloc() since the allocator state and free page count are
updated atomically and we expect them to stay in sync. On 12 the
bug would manifest as threads looping in vm_page_alloc().
