15.0/relnotes: Mention boot speedup in EC2
Most systems have only had modest improvements, but I did some work which
fixed issues specifically affecting EC2.
releases/15.0R/relnotes: setgroups(2), getgroups(2), initgroups(3) changes
Inline the points that must be audited. For the rest, redirect people
to the proper manual pages, where SECURITY CONSIDERATIONS sections were
added.

15.0: Fix freebsd-update instructions
Contrary to earlier belief, we're going to have freebsd-update
in 15.x after all.
But add a warning about applying the errata update first, since
systems will be rendered inoperative otherwise.
releases/15.0R/relnotes: Document AMD GPU slowness and VM domainset fixes
Replace the LinuxKPI paragraph talking only about handling the
__GFP_NORETRY flag in linux_alloc_pages() with the user-facing reason of
this work and an overview of other fixes towards this goal.
Add a separate paragraph about VM domainset iterator fixes, which were
prompted by the previous but are much larger in scope. One commit is
common to both paragraphs.
releases/15.0R/relnotes: User-facing description for mountd(8) change
Explain what this change means to users. The description from the
commit message was fairly incomprehensible from this point of view.
Fix the commit hash (it pointed to some MFC commit to stable/14).
While here, fix punctuation around the commit links and "Sponsored by
The FreeBSD Foundation" lines (see also note in the previous commit).
