b7041c0781 For open/openat, if the flags parameter does not contain O_CREAT, the 
3rd (variadic) mode_t parameter is irrelevant.  Many developers in the past
have passed mode_t (0, 044, 0644, or such), which might lead future people
to copy this broken idiom, and perhaps even believe this parameter has some
meaning or implication or application. Delete them all.
This comes out of a conversation where tb@ noticed that a strange (but
intentional) pledge behaviour is to always knock-out high-bits from
mode_t on a number of system calls as a safety factor, and his bewilderment
that this appeared to be happening against valid modes (at least visually),
but no sorry, they are all irrelevant junk.  They could all be 0xdeafbeef.

4b96984bb8 a first cut at requesting and parsing vpd info. 
reading vpd stuff is useful when you're trying to get support
information about a pci device, eg, if you want a serial number,
or firmware versions, or specific part name or number, it's likely
available via vpd. also, im sick of having the diff in my tree.

this relies on the new PCIOCGETVPD ioctl i just committed to the
kernel.

it's a very quick and dirty implementation, hopefully someone will
pick it up and polish it a bit.

c8d17636e0 pcidump(8) only opens devices in O_RDONLY from /dev, and additionally writes a 
`romfile' if -r is used, but since I'm only unveiling after that file is
actually opened there's no need to unveil it as well.

df69c215c7 When system calls indicate an error they return -1, not some arbitrary 
value < 0.  errno is only updated in this case.  Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

b9fc9a728f Replace <sys/param.h> with <limits.h> and other less dirty headers where 
possible.  Annotate <sys/param.h> lines with their current reasons.  Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc.  Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution.  These are the files confirmed
through binary verification.
