Replace uses of holdfp() with fget*() or fgetvp*() calls as appropriate
introduce fget(), fget_read(), fget_write() - these functions will take
a thread and file descriptor and return a file pointer with its ref
count bumped.
introduce fgetvp(), fgetvp_read(), fgetvp_write() - these functions will
take a thread and file descriptor and return a vref()'d vnode.
*_read() requires that the file pointer be FREAD, *_write that it be
FWRITE.
This continues the cleanup of struct filedesc and struct file access
routines which, when are all through with it, will allow us to then
make the API calls MP safe and be able to move Giant down into the fo_*
functions.
o Fix a number of wrong statements
o Clarify the structure of the files and the C structures theirselves
o Add cross-references to login(3), logout(3), logwtmp(3)

Without this, you'll see following messages when 'MAKEDEV all':

- Renumber labels since the previous revision removed one.
- Remove useless and wrong comment.
- Repeating the function name is just redundant.
- The previous revision made the comment about %edx useless.
- The comment about %eax was wrong (but did explain why %eax used to be
fixed up).

In src/Makefile rev 1.232, environment variable PATH is set explicitly
to /sbin:/bin:/usr/sbin:/usr/bin. As a result, binaries located on
non-standard path cannot be executed without full-path (it's the change
of this revision).
However, cvsup is not in our base system -- you lose if you try to
"make update" without setting SUP in make.conf or command line argument.
I think it is safe to assume that cvsup is located at /usr/local/bin,
and it would help other people who first try to do "make update".

Fix the WARNS 1 warnings except unused variables.
Add prototype for log_netobj().
Don't compare signed/unsigned.
Cast u_int64_t to 'unsigned long long' and print using %llu.
Fix constness of string arrays.
Use a cast to avoid an unused parameter in a signal handler.
alarm(2) can't fail, so don't check for it.
ANSI'ify some functions.
- Restore inferior() to being iterative rather than recursive.
- Assert that the proctree_lock is held in inferior() and change the one
caller to get a shared lock of it. This also ensures that we hold the
lock after performing the check so the check can't be made invalid out
from under us after the check but before we act on it.

reading cr.ivr, as well as writing to cr.eoi.
o use global variables to pass information to os_boot_rendez
so that it doesn't have to jump through hoops to find it
out. This avoids traps on the AP without it even being
initialized. This fixes SMP configurations.
o Move the probing of the MADT to the end of cpu_startup,
instead of at the start of cpu_mp_probe. We need to probe
the MADT for non-SMP configurations as well. This fixes
uniprocessor configurations.
o Serialize AP wake-up by waiting for the AP. We need to do
this since we use global variables to for the AP to use.
As a side-effect, we can use printf() more easily to see
what's going on.
to avoid the need for rpc.lockd to perform client locks. Using
this option a user can revert back to using local locks for NFS mounts
like we did before we had rpc.lockd.
