Support for Win32 safeseh (BR 195417)
This is basically not a bug report, but a feature request.
It's desired to be able to link .obj modules compiled with 'nasm -f
win32' with Microsoft 'link /safeseh'. As well as to register symbols
(commonly subroutine's entry points or even external symbols) as "safe
handlers." In order to achieve this, several points are required.
First of all, object module has to have absolute symbol named @feat.00
with value of 1. This can actually be achived by adding 'absolute 1'
and '@feat.00:' to source code, but it's desirable that it's
autogenerated for win32 modules.
Handler registration is essentially symbol's *index* in current
module's symbol table in .sxdata, segment with 0x200 segment flags, an
"info" segment. It's also essential that symbol has type 0x20 (see
below). All this is depicted in following framgents of 'objdump -xD'
output:
Sections:
Idx Name Size VMA LMA File off Algn
0 .sxdata
00000004 00000000 00000000 0000003c 2**2
CONTENTS, READONLY, DEBUGGING
SYMBOL TABLE:
...
[ 5](sec -1)(fl 0x00)(ty 0)(scl 3) (nx 0) 0x00000001 @feat.00

...
<.sxdata>
0: 06 00 00 00
Note [6] and (ty 20) in _handle line in SYMBOL TABLE. "06 00 00 00" in
.sxdata is little-endian 6, _handler's index. This is what makes up
"registration." It's impossible to achieve this with current nasm
facilities and it's probably appropriate to introduce a directive for
it, 'safeseh _handler' is probably most natural choice.

All singleton registers need to be displayable from register flags
alone!
When using the new 0360..0363 codes, make sure we appropriate avoid
displaying the legacy use of the prefixes.

Fix buffer overflow in preproc.c (BR 1942146)
Fix buffer overflow in preproc.c due to an incorrect test. In the
code:
for (r = p, s = ourcopy; *r; r++) {
if (r >= p+MAX_KEYWORD)
return tokval->t_type = TOKEN_ID; /* Not a keyword */
*s++ = tolower(*r);
}
*s = '\0';
... the test really needs to be >= since for the pass where there are
equal:
a) a nonzero byte means we have > MAX_KEYWORD characters, and
b) s = ourcopy+MAX_KEYWORD; but if the test doesn't trigger,
we can write one more character *plus* the null byte, overflowing
ourcopy.

UDx instructions are 186+, not 286+
The UDx instructions are valid as far back as the #UD trap, which is
the 186, not the 286.
