ValueFlow: Small cleanups
TemplateSimplifier: Fixed crash caused by null pointer dereference. I don't have a testcase. But the code is suspicious, in the loop we check if tok3 is null and then in the loop head we call tok3->next().
Fixed #5981 (FP: nullPointer on repeated switch)
Fixed copy and paste error (Coverity-ID: 1226262 Copy-paste error).
Tokenizer: Added missing comma in string array initialization (This fixes Coverity-ID: 1226263 Missing comma in a string array initialization).
Shorten code by using temp variables, cleanup variable names.
xml dump: remove duplicate attribute
xml dump: output a <variables> with all variables
xml dump: Fixed segfault when dumping symboldatabase variables
xml dump: fixed some minor issues in symboldatabase dump
xml dump: fixed some bad xml output in the token list dump
travis: check --dump
Merge pull request #365 from matthiaskrgr/travis_working

travis: check --dump
Merge pull request #364 from Dmitry-Me/tempVariablesAndBetterNames

Shorten code by using temp variables, cleanup variable names.
xml dump: Added tools/cppcheckdata.py that loads the dump.
xml dump: output some more info in the dump
xml dump: Read scope-type attribute in cppcheckdata.py module
xml dump: fixed cppcheckdata loader so previous/next will work
Use temp variable to omit recomputing the same value.
Fixed #5965 (False positive zerodiv - loop iterating over double variable)
