some unknown reason, when LOCAL_PATCHES and LOCAL_SCRIPT were originally
added, they were silently ignored if the actual file did not exist. As a
result, if one mistyped the pathname to a patch or script, then the release
silently succeeded. However, it was not built with the desired changes and
no warning was given to inform the builder either. This commit explicitly
checks to see that all of the defined patches and scripts exist up front
and bails if any of them do not exist. I lost several hours of valuable
sleeping time this evening due to this "feature" so I've finally gone and
ripped out. I've tripped over this in the past several other times as
well.

line as the announcement. Someone should probably update the "buffers
remaining" message since we now no longer should have any buffers remaining
at that point.
Until now the function has just returned zero for any event, but
that is downright wrong for MOD_UNLOAD and not very useful for any
future events we add where it may be crucial to be able to tell
if the event was unhandled or successful.
Change the function to return as follows:
MOD_LOAD -> 0
MOD_UNLOAD -> EBUSY
anything else -> EOPNOTSUPP
when the battery is fully charged. That breaks some of the arithmetic in
calculating the remaining capacity (ends up with more than 100%).
This commit makes sure the max is 100.

check to ensure that the caller is not prison root.
The intention is to fix file descriptor creation so that
prison root can not use the last remaining file descriptors.
This privilege should be reserved for non-jailed root users.

reduces the size of the pv_entry structure a small but significant amount.
This is implemented a little differently because it isn't so cheap to get
the physical address of the page tabke page on amd64.. instead of it
being directly accessible from the top level page directory, it is now
two additional tree levels down. However.. In almost all cases, we
recently had the physical address if the page table page a short while
before we needed it, but it slipped through our fingers. This patch
saves it for when we do need it. Also, for the one case where we do not
have the ptp paddr, we are always running in curproc context and so we
can do a vtopte-like trick. I've implemented vtopde() for this purpose.
There is still a CYA entry in pmap_unuse_pt() that needs to be removed. I
think it can be removed now but I forgot to test with it gone.
