6ff92c14b7 Implement readahead buffering for non-raw files. This drastically improves 
the efficiency of byte-by-byte read operations on filesystems not already
supported by the block cache (especially NFS).

This should be a welcome change for users booting via PXE, as the loader
now reads its startup files almost instantly, instead of taking tens of
seconds.

a07fee2cdf 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.

0f1968a738 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)

d53e4c1d80 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.

e29cc743ca Move setjmp/longjmp implementations here from libc; no signal handling

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.
