it possible to demote a mimmutable mapping's permissions from RW to R.
Further mimmutable-related work in libc's malloc created the same

the pointer to the expired clockintr during the dispatch loop in
clockintr_dispatch() after reentering cq_mtx. This means we will not
be able to safely check for the CLST_IGNORE_REQUESTS flag.
So replace the CLST_IGNORE_REQUESTS flag in cl_flags with the
CQ_IGNORE_REQUESTS flag in cq_flags. The semantics are the same.
Both cl_flags and cq_flags are protected by cq_mtx.
Note that we cannot move the CLST_IGNORE_REQUESTS flag to cr_flags in
struct clockrequest: that member is owned by the dispatching CPU and
is not mutated with atomic operations.

Whenever we have a libc major bump, we run the risk that dependent shared
libraries will request a different (major) libc version from the one
requested by the binary itself. For various reasons loading multiple libc
versions is not a good idea, and since the introduction of msyscall(2)
support, system calls will only work when called from one of the two loaded
libcs. This really means that when we have a libc major bump, users must
update all dynamic executables and shared libraries in the system.
However, to ease this transition, change ld.so to only load the first libc
version that we encounter (in a breadth first sense) and substitute that
libc version for all further loads of libc, even if different versions are
requested. This is done silently since I can't come up with a good warning
message. In practice this means the libc version requested by the
executable itself will be loaded. This means that shared libraries may
fail to load if they use a symbol that has been removed. But given the
constraints, this is the best that we can do. Even when we bump the
libc major, the set of changes is typically small and most binaries and
shared libraries will continue to run and allow the user to run pkg_add -u
without any fallout.

Prepare for removing most of the X509_TRUST API
X509_check_trust() is of course used by the verifier. Unfortunately
M2Crypto exposes it. The only other part of the X509_TRUST API that
are still needed are the X509_TRUST_* macros in x509.h, as they are
used via *_set_trust and indirectly via the purpose stuff. The rest
will be removed.
X509_TRUST_add() was defanged recently, in particular it no longer
hangs strdup()'ed strings off the global struct. Nothing ever cleaned
these up. TRUST_cleanup() attempted to do so, but since it checked
the dynamic/dynamic strings flags in the wrong order, that cleanup
call ended up doing nothing, so that code was removed at some point.
As a consequence, the struct can now be made const. Use a CTASSERT()
to ensure size assumptions on X509_TRUST_COUNT, X509_TRUST_MAX, and
X509_TRUST_MIN hold true.
Remove the global variable underlying X509_TRUST_set_default()'s
functionality and move its accessor down to all the other functions
that will be deleted.
Inline a few things in X509_check_trust(), so we can excise the
internals of X509_TRUST_get0(), X509_TRUST_get_by_id(). Since the
default trust function can no longer be changed, call obj_trust()
directly.

Remove check{,obj_cleanup}_defer documentation
Both check_defer() and the global variable obj_cleanup_defer were removed
from the public API two years ago. Now they were removed from the internals
as well, simplifying the cleanup process greatly. We no longer need them
to have a chance to understand the cleanup process. Also remove references
to EVP_cleanup() since this has long been deprecated and now it doesn't
clean up things anymore.

Said bug was fixed in OpenSSL 1.0.0, released 14 years ago. It is of course
