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.
ok guenther, millert, doug (helped with the verification protocol)

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)
ok with the idea millert, ok dms

Use sysctl to get the running kernel version instead of grotting
through kmem. Fixes false positives on machines where the memory
is not cleared between boots. OK deraadt@, tedu@, jaredy@

ansi and protos

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

kill more registers.

millert@ ok

Make kvm_mkdb work again
o testdb() needs to take as an arg the name of the kernel so it can do
the version test correctly.
o add undocumented verbose flag to tell when we are rebuilding the .db file
o DO_* -> _NLIST_DO_*, this prevented kvm_mkdb from doing anything at all.
o preserve a few error messages so you get error output when none of
the exec types match the target.
o check malloc return values
o get_kerntext should not subtract the sizeof(struct exec) from kernel_text

From NetBSD: make testdb() fail if database version string has length zero.
Also, KNF, b* -> mem*, getopt tests against -1, not EOF, and index -> strchr.
Added OpenBSD tags.
