xml dump: Added function attribute in scope
Fixed #5978 (false positive: Array 'm_pool_vector[-1]' accessed at index 0, which is out of bounds.)
xml dump: added 'astIsFloat' utility function in cppcheckdata.py
htmlreport: fix #5998, crash on some files with "UnicodeDecodeError".
For those files that we can't decode, don't generate a html-preview but note into index.html that we couldn't process the file.

xml dump: add more token attributes
htmlreport: sort error-data per line (in index.html page as well as in the defect list of the respective files.)
htmlreport: if no arguments are passed, print --help output; when done generating the report, print where index.html is (take report_dir into account).
htmlreport: don't crash when pygments fails to determine filetype of a file we want to highlight. This happens for files with no extension (for example "foo" instead of "foo.c").
htmlreport: on the index page, print stats of which warning ID occured how often.
