preproc: varargscount: bugfix for tokens starting with '(' not being counted

[mwierzbix]

; also introduced unit tests to check the issue

Signed-off-by: Michal Jerzy Wierzbicki michalx.wierzbicki@linux.intel.com

varargscount is macro META_COUNT_VARARGS_BEFORE_COMPILE

Fix for issue #542

[mwierzbix]

I am thinking about removing all whitespaces for this check in the future, as it really doesn't matter whether preprocessor gives us
uint32_t param0 , uint32_t... or
uint32_t param0,uint32_t...
as the compiler doesn't care.

Again, I'd rather not do this in bugfix PR.

New unit tests:

#define PARENTHESIS_PRE() (1+3)/2
#define PARENTHESIS_POST() 4/(3-1)
...
TEST_HERE_DECLARE(func_name, with_parenthesis_pre, 1, PARENTHESIS_PRE())
TEST_HERE_DECLARE(func_name, with_parenthesis_post, 1,PARENTHESIS_POST())

Great, Travis build for SUE hanged during docker pull (it is, even before attempting to build).

This day cannot get any better it seems.

@mwierzbix
Do not worry, I will retrigger the build for you.
And I think Travis have some magic word to rebuild the tset.

If you've sent a pull request: You can close the PR then open it again. This will trigger a new build.

@mwierzbix Fwiw, Travis can be restarted if you click on details and the rebuild.

@lgirdwood@xiulipan Thanks :)
Adding to what you said, you also have to be logged into Travis with your Github account (probably one being contributor to thesofproject) in order to schedule restart.
