In the 17 years since r30796, the mandatory keyword has never been used
in any files as far as I can tell, and is currently unused. Retire it.
Don't believe we have a requirement until after we've checked all the
known key words. This will make error messages slightly better in
weird corner cases, but should otherwise be a nop.
Move the check for standard keyword + optional inclusion specifier to
its proper location. Otherwise you could have 'file.c standard pci'
without an error. This construct isn't in our tree, and has no well
defined meaning.
Remove some unnecessary code.  The offsets read from the first block are
overwritten a few lines bellow.

Fix a logic error.  Because of this inflateReset() wasn't being called and
the output buffer wasn't being cleared between the inflate() calls,
producing zeroed output after the first inflate() call.

This fixes the read of mkuzip(8) images with geom_uncompress(4).

Slight cleanup to the error messaging to compress code vertically...
Fix a bug introduced in r261437 that failed to honor "optional
profiling-routine" to work, since profiling-routine is not really an
option or a device, but a special case elsewhere in the code.
Convert the loop by gotos into a for loop to improve readability. I
did this only with the inner loop for the token parsing, and not the
outer loop which was understandable enough when the extra layers of
looping went away...

Avoid doing unnecessary nested TLB invalidations.

Prior to this change the cached value of 'pm_eptgen' was tracked per-vcpu
and per-hostcpu. In the degenerate case where 'N' vcpus were sharing
a single hostcpu this could result in 'N - 1' unnecessary TLB invalidations.
Since an 'invept' invalidates mappings for all VPIDs the first 'invept'
is sufficient.

Fix this by moving the 'eptgen[MAXCPU]' array from 'vmxctx' to 'struct vmx'.

If it is known that an 'invept' is going to be done before entering the
guest then it is safe to skip the 'invvpid'. The stat VPU_INVVPID_SAVED
counts the number of 'invvpid' invalidations that were avoided because
they were subsumed by an 'invept'.

libc/net: Fix some issues in inet6_opt_init() (from RFC 3542):

* The RFC says (in section 10.1) that only when extbuf is not NULL,
extlen shall be checked, so don't perform this check when NULL is
passed.

* socklen_t is unsigned, so checking extlen for less than zero is
not needed.
