changes:

* fixed warnings
* support for options - actually only two options are supported -
quite and fatal_errors

these options are +/- useful - main reason for their existence is
testing of support of options - processing on CHECK ... stmt side and
processing on checker function side.

options are send as 2d text array - some like
'{{quite,on},{fatal_errors,on}} - so direct call of checker function
is possible

* regress test for multi check
