Overhaul the relnotes page to reorganize the sections.
With the previous layout, the majority of the release
notes were categorized under one main "What's New"
section, which in addition to making the page difficult
to parse relevant bits, also had a few rendering issues,
such as 'Note' blocks visually not appearing as if they
pertain to a particular change.
This change removes the "What's New" section, integrating
it with the introduction. In addition, each section now
provides a brief description of its contents, broken down
further into a subsection for each "topic", making it much
easier to find a specific topic in the page.

The flowid and hashtype should be copied from the originating packet

Reorganize the list of addresses associated with an interface and group them
based on the address family. This should help to recognize interfaces with
multiple AF (e.g. ipv4 and ipv6) with many aliases or additional addresses. The
order of addresses inside a single group is strictly preserved.
Improve the scope_id output for AF_INET6 families, as the
current approach uses hexadecimal string that is basically the ID of an
interface, whilst this information is already depicted by getnameinfo(3) call.
Therefore, now ifconfig just prints the scope of address as it is defined in
2.4 of RFC 2373.

CTL LUN mapping rewrite.
Replace iSCSI-specific LUN mapping mechanism with new one, working for any
ports. By default all ports are created without LUN mapping, exposing all
CTL LUNs as before. But, if needed, LUN mapping can be manually set on
per-port basis via ctladm. For its iSCSI ports ctld does it via ioctl(2).
The next step will be to teach ctld to work with FibreChannel ports also.
Respecting additional flexibility of the new mechanism, ctl.conf now allows
alternative syntax for LUN definition. LUNs can now be defined in global
context, and then referenced from targets by unique name, as needed. It
allows same LUN to be exposed several times via multiple targets.
While there, increase limit for LUNs per target in ctld from 256 to 1024.
Some initiators do not support LUNs above 255, but that is not our problem.

Add a quirk to limit AHCI MSI vectors to one
In 10.1-RELEASE the default number of MSI vectors used was changed from one

This change resulted in an ahci timeouts regression when running on AMD

Do not qualify the mcontext_t *mcp argument for set_mcontext(9) as
const. On x86, even after the machine context is supposedly read into
the struct ucontext, lazy FPU state save code might only mark the FPU
data as hardware-owned. Later, set_fpcontext() needs to fetch the
state from hardware, modifying the *mcp.
The set_mcontext(9) is called from sigreturn(2) and setcontext(2)
implementations and old create_thread(2) interface, which throw the
*mcp out after the set_mcontext() call.

The gpiobus is responsible to keep track of the used pins and serialize

not, until now, make use of the gpiobus locking).
