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.

macho_sectalign was occasionally misprinted
with macho_setcalign, fix it. No change on functionality.

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.

Put in all constants pecoff v8 states. Most probably we
will never need most of them but lets have them here for
completeness.

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.

This change may have backward compatibility issue but
most probably the sane program never used sections with
base address less then instruction alignment.
Note that alignment may only increase which means if a
section is aligned on 2^5 the align 2^4 will not affect
the section.

We already have "elf" and "macho" aliases for respective
32 bit output formats. Make the same for "win32" in a
sake of consistency.

nasm_opt_val should be able handle various text stream
passed, including tainted ones. Make it so.
Also it fixes the case when Elf section has multiple
attributes such as "progbits align=16" and friends
(introduced by commit bb0745f). The former just ignore
any other options/values except first one.

- no need to split functions even if it a bit longer
then 80 characters, it becomes hard to read it
- initialize "thead" before "tail" is more natural
- use more simple while() instead of for() with a
long initializer
