Remove Softdep.

Softdep has been a no-op for some time now, this removes it to get
it out of the way.

Flensing mostly done in Talinn, with some help from krw@

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.

related to the fsck changes, quotacheck must also determine & setup

Convert many atoi() calls to strtonum(), adding range checks and failure
handling along the way.

Replace <sys/param.h> with <limits.h> and other less dirty headers where

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.

FSTAB -> _PATH_FSTAB, the latter is deprecated.
From natano@bitrig, ok deraadt@

As suggested by guenther@ and millert@, replace seek+[read|write] with
p[read|write]. Makes the code much clearer by eliminating extra error
checking and verbiage.

No intentional functional change.

Let quotacheck work with duid based fstab. Missed one open() -> opendev()
from Rogier Krieger's original diff.

Found by and fix tested by dlg@

do not downsize a type before calling malloc

fix some leaks
ok miod@

Hammer fstab entries and command line entries into same format with
realpath() and opendev() so duid and device names work consistantly.
Also lets duid fstab entries work.
