Refactored the clamscan code that determines 'what to scan' in order
to clean up some very messy logic and also to get around a difference in
how vscode and clang-format handle formatting #ifdef blocks in the
middle of an else/if.
In addition to refactoring, there is a slight behavior improvement. With
this change, doing `clamscan blah -` will now scan `blah` and then also
scan `stdin`. You can even do `clamscan - blah` to now scan `stdin` and
then scan `blah`. Before, The `-` had to be the only "filename" argument
in order to scan from stdin.
In addition, added a bunch of extra empty lines or changing multi-line
function calls to single-line function calls in order to get around a
bug in clang-format with these two options do not playing nice together:
- AlignConsecutiveAssignments: true
- AlignAfterOpenBracket: true
AlignAfterOpenBracket is not taking account the spaces inserted by
AlignConsecutiveAssignments, so you end up with stuff like this:
```c
bleeblah = 1;
blah = function(arg1,
arg2,
arg3);
// ^--- these args 4-left from where they should be.
```
VSCode, meanwhile, somehow fixes this whitespace issue so code that is
correctly formatted by VSCode doesn't have this bug, meaning that:
1. The clang-format check in GH Actions fails.
2. We'd all have to stop using format-on-save in VSCode and accept the
bug if we wanted those GH Actions tests to pass.
Adding an empty line before variable assignments from multi-line
function calls evades the buggy behavior.
This commit should resolve the clang-format github action test failures,
for now.
