09086b0499 Bring back the cd -L and -P options from revision 1.24, but try harder not
to fail when the logical current directory no longer exists. Allow changes
to absolute paths when logical cwd is invalid, fall back to physical cd
if logical cd fails.

baf3e7c14b Temporarily back out revision 1.24; it seems to handle the case where the
current directory no longer exists incorrectly and breaks `make cleandir'.

ddbbc9628d Permit alternative break sequence to break to debugger in GENERIC. Breakage
of serial break on -CURRENT seems rampant for some reason, and I like
being able to get into ddb.

703fc290fb Add appropriate IA32 "pause" instructions to improve performanec on
Pentium 4's and newer IA32 processors.  The "pause" instruction has been
verified by Intel to be a NOP on all currently existing IA32 processors
prior to the Pentium 4.

ec41816009 - td will never be NULL, so the call to soalloc() in socreate() will always
be passed a 1; we can, however, use M_NOWAIT to indicate this.
- Check so against NULL since it's a pointer to a structure.

1515cd22e1 - OR the flag variable with M_ZERO so that the uma_zalloc() handles the
zero'ing out of the allocated memory.  Also removed the logical bzero

2498cf8c42 Add code to make default mutexes adaptive if the ADAPTIVE_MUTEXES kernel
option is used (not on by default).

- In the case of trying to lock a mutex, if the MTX_CONTESTED flag is set,
  then we can safely read the thread pointer from the mtx_lock member while
  holding sched_lock.  We then examine the thread to see if it is currently
  executing on another CPU.  If it is, then we keep looping instead of
  blocking.
- In the case of trying to unlock a mutex, it is now possible for a mutex
  to have MTX_CONTESTED set in mtx_lock but to not have any threads
  actually blocked on it, so we need to handle that case.  In that case,
  we just release the lock as if MTX_CONTESTED was not set and return.
- We do not adaptively spin on Giant as Giant is held for long times and
  it slows SMP systems down to a crawl (it was taking several minutes,
  like 5-10 or so for my test alpha and sparc64 SMP boxes to boot up when
  they adaptively spinned on Giant).
- We only compile in the code to do this for SMP kernels, it doesn't make
  sense for UP kernels.

Tested on:	i386, alpha, sparc64

07107de9bc Introduce the concept of "magic spaces", and implement them in most of
the relevant classes.

Some methods may implement various "magic spaces", this is reserved
or magic areas on the disk, set a side for various and sundry purposes.
A good example is the BSD disklabel and boot code on i386 which occupies
a total of four magic spaces: boot1, the disklabel, the padding behind
the disklabel and boot2.  The reason we don't simply tell people to
write the appropriate stuff on the underlying device is that (some of)
the magic spaces might be real-time modifiable.  It is for instance
possible to change a disklabel while partitions are open, provided
the open partitions do not get trampled in the process.

21b8b7cb3c Make ReadMakefile() operate using the realpath(3) name for the file handed to
it, which means that relative paths will be expanded to absolute paths, and
filenames without a path will end up with their absolute path included as
well.  This aids tremendously in debugging a build using our make(1) with
multiple Makefile's, such as when there is a syntax error in a file in a
sub-directory as per <bsd.subdir.mk>.  Normally we'd end up with just
"Makefile" known about the Makefile in question, which means that an error
would be useless for someone trying to debug their build system, now we
end up with a complete real pathname for the Makefile.

So mostly this is useful in a debugging context, but possibly others too
(I haven't thought of them yet, but they probably are more useful if you
make Dir_FindFile use realpath(3), but that's another story).
