Add basic command line parsing test coverage for these utilities. The tests
were automatically generated based on their man pages. These tests can be
expanded by hand for more thorough coverage. The aim is to generate very
basic amount of test coverage for all the utilities in the base system.

efidp_size will return the size, in bytes, of a EFI device path

Rename boot1's wcslen to ucs2len, which we can't use in userland
because wchar in userland is unsigned, not short. Move it into

trailing NUL to transition the FreeBSD boot env vars to being NUL
terminated on the same line...

When bcopy is treated as memcpy/memmove, Clang produces warnings that the
size argument doesn't match the type of the source. This is true, it
doesn't match; we're aliasing the source.
Explicitly cast the source pointer to the expected type to remove the
warning.

SCM_REALTIME and SCM_MONOTONIC from 64-bit to its 32-bit

This modification adds a new gettytab(5) option (iM) to specify a
program to run that will generate the initial (banner) message that is
displayed before the login prompt. Such a capability is useful when
dynamic information is needed in the banner message that cannot be
supplied by the set of % substitution sequences available in the "im"
option.

While __read_mostly groups variables together, their placement is not
specified. In particular 2 frequently used variables can end up in
different lines.
This annotation is only expected to be used for variables read all the time,
e.g. on each syscall entry.

While these locks are guarnteed to not share their respective cache lines,
their current placement leaves unnecessary holes in lines which preceeded them.
For instance the annotation of vm_page_queue_free_mtx allows 2 neighbour
cachelines (previously separate by the lock) to be collapsed into 1.
The annotation is only effective on architectures which have it implemented in
their linker script (currently only amd64). Thus locks are not converted to
their not-padaligned variants as to not affect the rest.

Add the required structure bits in order to support a backpressure
indication with ratelimited connections aswell as non-ratelimited
ones. The backpressure indicator is a value between zero and 65535
inclusivly, indicating if the destination transmit queue is empty or
full respectivly. Applications can use this value as a decision point
for when to stop transmitting data to avoid endless ENOBUFS error
codes upon transmitting an mbuf. This indicator is also useful to
reduce the latency for ratelimited queues.
