This can happen on Plan 9 if we we're building
with the 32-bit and 64-bit host compilers, one
after the other.

8c: handle 64-bit switch value

Change the name of cas() in cc to newcase() to avoid a NIX conflict.
cas() is used in cc to create a new Case struct. There is a name
conflict in that cas() is a commonly-used
name for compare and swap. Since cas() is only used internally
in the compiler in 3 places, change the name to avoid a wider
conflict with the NIX runtime. This issue might well come up on
other OSes in the future anyway, as the name is fairly common.

#pragma varargck countpos f 1
says that the first argument to f is
the count of variadic arguments that follow.
#pragma varargck type f t
says that t is one of the allowed types for
a variadic argument to f.
(can be repeated)
combined, these can be used to check the
runtime.stdcall functions in the windows port
or in any other port that needs a vararg list of
uintptrs even on a 64-bit platform (where it is
very easy to pass a less-than-uintptr in the ...).
demo:
typedef unsigned int uintptr;
#pragma varargck countpos f 1
#pragma varargck type f uintptr
#pragma varargck type f void*
int f(int count, ...);
void *v;
char *p;
void
main(void)
{
f(1, v); // ok
f(1, main); // ok
f(1, p); // ok
f(2, v, v); // ok
f(2, v); // found 1 argument after count 2
f(1, 'a'); // invalid type INT in call to f
f(1, 0); // invalid type INT in call to f
}

8a/a.h:
. Removed <u.h> and <libc.h> includes as they work better in "a.y".
. Made definition of EOF conditional as it's defined in the Plan 9
header files, but not elsewhere.
8a/a.y:
. Added <u.h> and <libc.h> because <stdio.h> in Plan 9 needs them.
Sequence <u.h>, <stdio.h>, <libc.h> recommended by RSC.
8a/lex.c:
. Added <u.h> and <libc.h> as now needed by "a.h".
. Dropped <ctype.h>.
cc/lexbody:
. exit() -> exits().
. Dropped unwanted incrementation.
cc/macbody:
. Adjusted a few format specifications.

The Plan 9 tools assume that long is 32 bits.
We converted all instances of long to int32 when
importing the code but missed the print formats.
Because int32 is always int on the compilers we use,
it is never correct to use %lux, %ld, etc. Convert to %ux, %d, etc.
(It matters because on 64-bit gcc, long is 64 bits,
so we were printing 32-bit quantities with 64-bit formats.)

Use OS rather than compiler specific flag the same way that
__FreeBSD__, __APPLE__, __OpenBSD__, and __linux__ are used.
_WIN32 is defined by GCC (and others) on windows for Win32
and Win64 applications. _WIN32 is set by default for several
other windows based compilers: DMC, MSVC, Intel, Watcom, LCC.
Although the change is for consistency, it allows the Go tools
to be compiled with non-Mingw GCC distributions and non-GCC
compilers that support the GCC extensions.

5g/6g/8g: add import statements to export metadata, mapping package path to package name.
recognize "" as the path of the package in export metadata.
use "" as the path of the package in object symbol names.
5c/6c/8c, 5a/6a/8a: rewrite leading . to "". so that ·Sin means Sin in this package.
5l/6l/8l: rewrite "" in symbol names as object files are read.
gotest: handle new symbol names.
gopack: handle new import lines in export metadata.
Collectively, these changes eliminate the assumption of a global
name space in the object file formats. Higher level pieces such as
reflect and the computation of type hashes still depend on the
assumption; we're not done yet.

* switch to real dot (.) instead of center dot (·) everywhere in object files.
before it was half and half depending on where in the name it appeared.
* in 6c/6a/etc identifiers, · can still be used but turns into . immediately.
* in export metadata, replace package identifiers with quoted strings
(still package names, not paths).

getquoted() currently checks for whitespaces and returns nil
if it finds one. this prevents us from having go in a path
containing whitespaces, as the #pragma dynld directives are
processed through the said function.
this commit makes getquoted() accept whitespaces, and this is
also needed for solving issue #115.

Currently, -I switch can't deal with a path containing spaces.
This commit simplify setinclude(), by removing the special case
of a string that had spaces. After this change, setinclude() will
merely add the given directories to the include path, if it does
not yet exist, and this approach works.
Will be needed for solving issue 115.

in a .6 file, an export line
//ffi T localfib remotefib remote.so
means the dynamic linker should initialize
localfib, always a pointer, to the address of
remotefib, either text (T) or data (D) after
loading remote.so.
the C compiler will generate an export section
when given the pragmas
#pragma package fib
#pragma ffi T localfib remotefib remote.so
needing #pragma package is a bit of a kludge
and hopefully could go away later.
this is just the 6 tool chain support.
other architectures will happen once 6 settles down.
code using this to do FFI is in a later CL.

these guys really really want long to be 32-bits,
so ,s/long/int32/ (and then manual fixup).
still passes all tests.
(i started out looking for just those longs that
needed to be int32 instead, and it was just too hard
to track them down one by one.)
the longs were rare enough that i don't think
it will cause integration problems.
