c536ef83f0 Fix the real problem that broke the Alpha loader this last week. It
was not the fault of the module code, nor FICL.  The malloc code requires
sbrk() to return addresses that were at least 16 byte aligned.  If the
Alpha loader happened to be 8 byte but not 16 byte aligned in length, then
you would get a zfree() panic at startup.

Incidently, this affected the i386 loader as well, and explains why
the static heap changed things and why jlemon had trouble when the bss
was not ending at a multiple of 8 bytes.

My fix is to 16 byte align it on all arches, even though the x86 version
only required 8 byte alignment (struct MemNode is smaller there).  We could
page align it if we wanted to be paranoid, but it isn't presently necessary.

72c520e887 We compile expressly on the alpha with -mno-fp-regs - so do not use them
explicitly here. This was the original cause of instruction faults on
the Alpha in loader. (not this code, but the same problem in libficl.a)

f12d45d9d6 Do not attempt to free a nfs node if it is the root node. The root
node is statically allocated and is not guarded, so free will panic
in nfs_close.

c6ff3a1bf7 Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

c35874acaa Add two new functions cd9660_readfile() & cd9660_readdir(), which
cd9660_read() now uses to read CDROMs.  With these changes FreeBSD/Alpha
can now boot from a bootable CDROM.

c447342094 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

59e1f32482 Tidy up some loose ends. nullfs_read/write were returning the wrong value.
Fix some ctype problems - isascii() caused a warning if fed an unsigned
char - it's always > 0 and libstand is compiled with -Wall.

0fbac2a6c5 longjumperror() and abort() don't exist in libstand.. Don't test
for a condition we can't handle (like the x86 longjmp).  This was
highlighted by attempting to build FICL into the alpha loader.

dcb0ae4ed8 More egcs warning fixes:
o use braces to avoid potentially ambiguous else
	o don't default to type int (and also remove a useless register
	  modifier).
	o Use parens around assignment values used as truth values.
	o Remove unused function.

a79658408c POSIX introduced optreset to deal with multiple invocations
of getopt (as in, multiple input lines :). This is documented in the
man page and is used in the code, but unistd.h and stand.h do not
declare it. Incidentally, it prevents me fixing a bug in loader's
code... :-)

b8ffd2a51c Well I never. Seems like _setjmp()/_longjmp() are just what the doctor
ordered.  This brings the Alpha back to parity, and should bring us
BootForth on both platforms.

25c3957dfd Move setjmp/longjmp implementations here from libc; no signal handling
in libstand, only for i386 until I locate an alpha setjmp/longjmp.

Minimal 64-bit gcc integer support for i386.  This is kinda nasty, and
should be revisited once we decide whether the bootblocks need
quad arithmetic.

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.

95b50c2be3 Replace the old and extremely icky Mach/NetBSD allocator with a similarly
compact and much better one donated by Matt Dillon.  Implement a simple
sbrk() which uses the existing setheap() api.

Remove the custom allocator from the UFS code.  It wasn't working quite
right, and it shouldn't be needed with the new allocator.

Fix a serious problem with changing the value of already-existent
environment variables.  Don't attempt to modify the supposedly-const
argument to putenv()

Fix an off-by-one sizing error in the zipfs code detected by the new
allocator.
