Revert recent changes, which either don't work, or can't be built

as pointed out by simonb, since we've moved to ELF __main() calls
aren't emittid anymore.

rename the C main() function to main_(). this avoids gcc's implicit
call to __main(), and therefore saves the size of the call and the
size of a stub implementation of __main().
in the primary boot block, don't bother saving/restoring the argument
passed in from the caller. There is no such argument (that we care
about, at least) to the primary. (for secondary, it's the firmware
FD being used.)

Bug fix for the bug fix. Be sure to prom_close() in bootxx and boot, but not
in netboot, and not in diskclose(), but after trying all kernelnames[].

Grab booted_dev_fd parameter from bootxx. It won't be there for netboot
but there should be no harm done.

vm_offset_t -> {paddr_t,vaddr_t}, vm_size_t -> vsize_t

Implement the 'i' flag which makes the bootloader ask for the file to
load (as in OSF/1).
Useful for netboot where "-file" doesn't work as needed.

clean up the way bootinfo information is passed and used: move the version
number passed by the boot block into a register, change the kernel's
bootinfo handing so that it always uses bootinfo to get bootinfo-ish values
(filling them in if the boot blocks didn't pass them), and make versioning
a small bit more sane.

While here in alpha/stand, add a technically required imb coherency op
just before transferring to the kernel entry point.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

Experimentation reveals that the implementation of GET_ENV on at least

character arrays to 4-byte boundaries by default, so it's possible to get
unlucky and die in the boot blocks with a "kernel stack not valid halt".

Avoid the problem by using a local, aligned buffer as the argument to GET_ENV,
and copying the result into the caller's buffer.

In putchar(), don't open-code two calls to the prom puts routine. Instead,
