In case if section follows itself we should yield
an error, otherwise we hit nil dereference because
there won't be any group of sections.
After all "follow" attribute is rather to group
sections other than self.

If macro is undefined while it's being expanded, use after free occurs,
since the MMacro instance is released, but it is still used to proceed
the expansion.
This change forbids macro undefinition: non-fatal error is raised and
the MMacro instance is not released if it is being processed by NASM
preprocessor.
Consider the following example:
| $ cat test.asm
| %macro m 0
| %unmacro m 0
| %endmacro
| m
| $ ./nasm test.asm
| test.asm:4: error: `%unmacro' can't undefine the macro being expanded
| test.asm:2: ... from macro `m' defined here

Lets run it as win32 since they are sharing
backends in most places but win32 is a way
more widely used.

It is failing right now so I'm not sure if
masm test is correct one. Lets merge it in
this form and update if needed.

Compared to 2.12.xx rdfwriteheader() writes the object length and header
length in flipped order. Issue seems to have been introduced by commit

In 78f14ab1a6 the fix
is incomplete, we should move free procedure out of
the list_for_each traverse.

Better point out explicitly that SMacro::next member
is untouched, thus do not use SMacro::next and an array.

If new list is not needed then we should free memory
allocated by nasm_basename and nasm_dirname calls.

Coverity scan tool complains on rdffile::rdoff_ver member
being called with memcpy uninitialized. Lets zap this

Currently we strip newlines from files on read and write
procedures for better diff output, but as being pointed
by hpa@ this makes quite inconvenient to work with tests
in a manual mode.
Thus lets left outputs as is. We have to update all tests
with template outputs since by default output streams are
ending with newline.

When we process a TOKEN_QMARK we also need to advance p, in order to
get the proper start for the next token.
This fixes travis test br3392707.

Fix circular dependency on asm/warnings.c by factoring out
warnings.$(O) from the dependencies, and use a separate <file>.time
which "generate" the main source file as a "side effect", giving us a
null target.
