but we need buffer of MLEN bytes. This isn't just a simplification,
but important fixup, because previous commit shrinked sizeof(struct
mbuf) down below MSIZE, and instantiating an mbuf on stack no longer
provides enough data.

The following series of patches addresses three things:
Now that array of pages is embedded into mbuf, we no longer need
separate structure to pass around, so struct mbuf_ext_pgs is an
artifact of the first implementation. And struct mbuf_ext_pgs_data
is a crutch to accomodate the main idea r359919 with minimal churn.
Also, M_EXT of type EXT_PGS are just a synonym of M_NOMAP.
The namespace for the newfeature is somewhat inconsistent and
sometimes has a lengthy prefixes. In these patches we will
gradually bring the namespace to "m_epg" prefix for all mbuf
fields and most functions.
Step 1 of 4:
o Anonymize mbuf_ext_pgs_data, embed in m_ext
o Embed mbuf_ext_pgs
o Start documenting all this entanglement

mac_bsdextended(4), when enabled, causes ordinary operations to send many
more VOP_GETATTRs to file system. The fusefs tests expectations aren't
written with those in mind. Optionally expecting them would greatly
obfuscate the fusefs tests. Worse, certain fusefs functionality (like
attribute caching) would be impossible to test if the tests couldn't expect
an exact number of GETATTR operations.
This commit resolves that conflict by making two changes:
1. The fusefs tests will now check for mac_bsdextended, and skip if it's
enabled.
2. The mac_bsdextended tests will now check whether the module is enabled, not
merely loaded. If it's loaded but disabled, the tests will automatically
enable it for the duration of the tests.
With these changes, a CI system can achieve best coverage by loading both
fusefs and mac_bsdextended at boot, and setting
security.mac.bsdextended.enabled=0

The changes in r359374 added various sanity checks in sessions and
requests created by crypto consumers in part to permit backend drivers
to make assumptions instead of duplicating checks for various edge
cases. One of the new checks was to reject sessions which provide a
pointer to a key while claiming the key is zero bits long.
IPsec ESP tripped over this as it passes along whatever key is
provided for NULL, including a pointer to a zero-length key when an
empty string ("") is used with setkey(8). One option would be to
teach the IPsec key layer to not allocate keys of zero length, but I
went with a simpler fix of just not passing any keys down and always
using a key length of zero for NULL algorithms.

Specifically, this removes support for the following ciphers:
- des-cbc

The addition of the HSM SBI extension to OpenSBI introduces a new
breaking change: secondary harts will remain parked in the firmware,
until they are brought up explicitly via sbi_hsm_hart_start(). Add
the call to do this, sending the secondary harts to mpentry.
If the HSM extension is not present, secondary harts are assumed to be
released by the firmware, as is the case for OpenSBI =< v0.6 and BBL.
In the case that the HSM call fails we exclude the CPU, notify the
user, and allow the system to proceed with booting.

Factoring some of the code in nfsm_dissct() out into separate functions
allows these functions to be used elsewhere in the NFS mbuf handling code.
Other uses of these functions will be done in future commits.
It also makes it easier to add support for ext_pgs mbufs, which is needed
for nfs-over-tls under development in base/projects/nfs-over-tls.
Although the algorithm in nfsm_dissct() is somewhat re-written by this
patch, the semantics of nfsm_dissct() should not have changed.
This option was added as a transition aide when symbol versioning was
first added. It was enabled by default in 2007 and is supported even
by the old GPLv2 binutils. Trying to disable it currently fails to
build in libc and at this point it isn't worth fixing the build.

The previous interface was pretty bad, and required the caller to get some
implementation details correct that it really shouldn't need to (e.g.
loader_conf_files handling) and pass in an empty table for it to use.
The new and much improved interface, readConf, is much less of a hack;
hiding these implementation details and just doing the right thing.
config.lua will now use it to process /boot/defaults/loader.conf and the
subsequent loader_conf_files from there, and read-conf will also use it.
This improvement submitted by Olivier (cited below), loader_conf_files
handling from the original patch was changed to just clobber it before
processing and not bother restoring it after the fact following r360505
where it's now guaranteed to evade the loader environment.
