Basically it's backport of commits

They were missed to back-merge in a first place.

There is no need to hide this structure into a type.
The former preproc_ops is a way more descriptive.

2.09 series was the last one we support context-thru search
(and we were issuing a warning about that) so drop all-context
from get_ctx() routine.

This reverts commit cb00cd1ba7f07f60f0a94c43cfc4fa7b01e2ff95.
As Victor pointed out some tests do not pass with this commit
so revert it until things get fixed.

It's a bit more than that, also TRACE=1 make
flag added to run this facility on and off
at compiling time.
Debug feature only, doesn't affect regular users.

There is no way to make it as a helper function
for a while, we need to unify list processing
in general (ie to use abstract list type).

This allow us to write the whole expressions
on section alignments, such as
align 0xa+6
or whatever math. Should be a way more convenient
than hardnumbers scheme we had.

We simply allow the following terminals to be concat'ed
if they are written without space or any other separator
inbetween.
a := id | preproc-id | number | float | other
b := id | preproc-id | number | float | other
if match(a,b):
s := concat(a,b)
re-tokenize(s)
Basically it means it's up to code author to write
preproc code a way the sane production appears.
Some notes.
1) We don't concat strings.
2) The 'weirdpaste' test fails now because with relaxed
rules it works as needed and was borken before.
The lacmus snippet is
%define N 1e%++%+ 5
dd N, 1e+5
Previously the output was
dd 1e+%+ 5, 1e+5
which is wrong since we have explicit concat here
with %+ operator. The new code production is correct
and looks like
dd 1e+5, 1e+5
as expected.

__OUTPUT_FORMAT__ must consist of shortname of output format
or its alias, otherwise userspace ABI gets broken.
For example source code still can refer to __OUTPUT_FORMAT__=elf,
instead of __OUTPUT_FORMAT__=elf32.
