Fix an inconsistency in treatment of trailing / in path::const_iterator

When using a //net/ path, we were transforming the trailing / into a '.'
when the path was just the root path and we were iterating backwards.
Forwards iteration and other kinds of root path (C:\, /) were already
correct.

Replace the F_Binary flag with a F_Text one.

Forgetting to set F_Text produces one that cannot be read in notepad, which
is a better failure mode :-)

Simplify remove, create_directory and create_directories.

Before this patch they would take an boolean argument to say if the path
already existed. This was redundant with the returned error_code which is able
to represent that. This allowed for callers to incorrectly check only the
existed flag instead of first checking the error code.

Instead, pass in a boolean flag to say if the previous (non-)existence should be
an error or not.

Callers of the of the old simple versions are not affected. They still ignore
the previous (non-)existence as they did before.

Use mkdir instead of stat+mkdir.

This is an optimistic version of create_diretories: it tries to create the
directory first and looks at the parent only if that fails.

Use mkdir instead of stat+mkdir.

This is an optimistic version of create_diretories: it tries to create the
directory first and looks at the parent only if that fails.

Running strace on "mkdir -p" shows that it is pessimistic, calling mkdir on
every element of the path. We could implement that if needed.

In any case, with both strategies there is no reason to call stat, just check
the return of mkdir.

Path: Recognize Windows compiled resource file.

Some background: One can pass compiled resource files (.res files) directly
to the linker on Windows. If a resource file is given, the linker will run
"cvtres" command in background to convert the resource file to a COFF file
to link it.

What I'm trying to do with this patch is to make the linker to recognize
the resource file by file magic, so that it can run cvtres command.
