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.

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.

Fix kernel profiling on MP systems by using per-CPU buffers and teach
kgmon(8) to deal with them, this time without public header changes.

Previously various CPUs were iterating over the same global buffer at
the same time to modify it and never ended.

This diff includes some ideas submited by Thor Simon to NetBSD via miod@.

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable).  these days, people use source.  these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)

From dhill@ last year:
- rename system to sys to stop shadowing the system() call.
- remove variable names in function declarations
- remove extern optarg and optind since it's defined in unistd.h
- use %zu instead of %d to print size_t's

Part one of userland __P removal.  Done with a simple regexp with some minor hand editing to make comments line up correctly.  Another pass is forthcoming that handles the cases that could not be done automatically.
