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

This allow us to keep compatibility layer without
needing the separated struct ofmt for this and
elf_init_hack routine.

In case if we can't open "malloc.log" for writing
we should not hang out but rather switch to stderr
and continue processing.

We need to compensate the index for two specials, not just one. While
we're at it, actually derive the number of specials from the list.

Distinguish the case of no directive present (D_none) from the case of
an unknown specified directive (D_unknown). This is reflected in
different error messages.
Furthermore, change the special case symbols to lower case in case we
ever have a directive called [none] or [unknown].

The former changes have been committed to binutils.

| opcodes/
| * i386-dis.c (OP_LWP_I): Removed.
| (reg_table): Do not use OP_LWP_I, use Iq.
| (OP_LWPCB_E): Remove use of names16.
| (OP_LWP_E): Same.
| * i386-opc.tbl: Removed 16bit LWP insns. 32bit LWP insns
| should not set the Vex.length bit.
| * i386-tbl.h: Regenerated.

So there is no 16 bit instructions anymore.
Also xop.l field should be set to 0.
