Apparently some people still care about compiling native on MS-DOS,
and we don't have a significant number of files which need adjustment.

Peter proposed to expand local single macros unconditionally.
This should not hurt but give us more cleaner code in result.

Introduce an ability to expand multi-line macros parameters in
a range/sequence manner.
For this purpose a special form is introduced %{x:y} which means to
expand %{x:y} to %{x},%{x+1},%{x+2},...,%{y}.
Both arguments could be negative or positive but MUST NOT be zero.
The arguments take into account possible %rotate as well.
Note that unlike the approach implemented in yasm we refer :-1 as
_last_ argument passed to a macro call, this makes possible to refer
the last element from macro via record as %{-1:-1} which could be
a convenient trick.
Also you can refer the argument in reverse order, ie it's legitime
to write %{5:4}, or even to reverse the all arguments %{-1:1}.
An example
|
| %macro mpar 1-*
| db %{1:-2}
| %endmacro
|
| mpar 1,2,3,4,5,6
in result we'll get the sequence of 1,2,3,4,5

ARRAY_SIZE is a well known name pointing out that
we're dealing with array in macro argument.
Also to be on a safe side prefix_name helper should
check the index been in bounds more precisely.

TOK_OTHER is legitime to follow TOK_PREPROC_ID so don't forget to handle it as well.

When we have switched to unified token pasting code we loose
backward compatibility. Restore it.
Note that new code MUST not expluatate this facility but rather
use paste macro %+ explicitly.
N.B. this patch is probably the candidate for revert, though
to give it a chance I commit it.

Add OUT_REL1ADR (one-byte relative address) and support for
OUT_ADDRESs with size == 1. Add support for it in
outbin and outdbg. *It still needs to be added to other backends*,
both the OUT_REL*ADR and OUT_ADDRESS codepaths need to be handled.

format_mode is always set to 1 so there is no need to
keep this variable. "Old chicken bit" (c) :)

Section alignment is broken due to not being
direct "align -> power of two set" mapping but
rather including second addition operation.
Fix it by introducing coff_sectalign_flags helper.
This also allow us to use this helper for getting
rid of open coded computation as well.

Add ilog2_{32,64}() and alignlog2_{32,64}() ... the latter is intended
for alignment statements and return -1 for non-power-of-2 other than 0
(which returns 0).

Achieved via sectalign call. Note that not all output
targets (ie formats) may handle sectalign yet, most
of them just ignore this entity.
