4da8edd59e Since vfork() was changed to fork(), we have to pass errno back from the
child to the parent somehow.

5a911c6263 Implement a hook to allow us to reclaim the memory used by the first stage
of the bootstrap (the bit which loads /boot/loader).

d58fb9293a To clarify last commit, msmith says:
The reason the Alpha has less room than the i386 is because the bootstrap
is given a 256K mapping by the firmware; to add more requires extra work.

95f5cf3349 Reduce the sbrk() increment from 64K to 4K. There's not much room on the
Alpha, and wasting potentially 64K-4 bytes of RAM just isn't an option.

01a4eb824c Add man pages for many of the functions in the CAM library. This covers
most of the open/close routines, and the buffer/cdb parsing routines
derived from the old scsi(3) library.

The cam_cdbparse(3) man page borrows from the old scsi(3) man page, so the
copyright and history section reflect that.

The many scsi_* functions and other functions that are pulled in from the
kernel aren't documented yet, but will be eventually.

1fd98d7d88 Calls one or more of malloc(), warn(), err(), syslog(), execlp() or
execvp() in the child branch of a vfork(). Changed to use fork()
instead.

Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

621a60d46b Add a "dummy light" (actually two dummy lights) to catch people who don't
have the passthrough device configured in their kernel.

This will hopefully reduce the number of people complaining that they can't
get {camcontrol, xmcd, tosha, cdrecord, etc.} to work.

b2d3d0f097 Avoid the "Cannot allocate memory" problem that appears on heavily
loaded systems by retrying the sysctl() with a larger buffer if it
fails with ENOMEM. For good measure, allocate 10% more memory than
sysctl() claims is necessary.

13a5277c23 Fix a curses bug exposed by the ":numbers" display of systat -iostat.
This bug showed up when you had more than 3 devices displayed.  (thus
requiring a second line of display)

Here's a quote From the PR:

 When wrefresh() is called with a subwindow as argument, __set_subwin
 might be called with reversed arguments if wrefresh() decides to calls
 quickch().  This may cause use of negative array indexes, with a
 resulting segfault.

 Since quickch() manipulates the line structures belonging to curscr,
 it looks like all subwindows of curscr should be updated.

a9d7016af5 Fixed removing of obsolete shared libraries:
- the directory was wrong if ${SHLIBDIR} != ${LIBDIR}.  It's still wrong
  if the installation of the obsolete library was done before /aout was
  appended to LIBDIR.
- the version would have become wrong when the default in ../Makefile.inc
  is changed from 2.0.
- the comment mostly described moving of libraries to /usr/lib/compat, but
  we don't do that.

in the wrong places for a while.
Also, the the libtermlib.so -> libtermcap.so manually for elf, otherwise
the hard link follows the symlink and the result looks rather wierd.  The
*.a files are still hard linked under elf as before.

0890dc6f44 vfork -> fork. The child calls execl() which calls malloc(), so
vfork() can't be used.  We could use alloca() in execl() so that
it can be called between vfork() and execve(), but a "portable"
popen() shouldn't depend on this.  Calling execle() instead of
execl() should be fairly safe, since execle() is supposed to be
callable from signal handlers and signal handlers can't call
malloc().  However, execle() is broken.
