Format and typelimit warnings (#169)

* merge with origin 4fc7dbc3 8daa8346

* fixed whitespace diff

* added .gitignore

* added format warning flags to C_FLAGS
added typelimit check to C_FLAGS and CXX_CLAGS

* Revert "added format warning flags to C_FLAGS"

Apply to branch format_and_typelimt branch

This reverts commit bf7467e82e.

* check for format warnings to top level C_FLAGS
added typelimit warnings to top level C_FLAGS and CXX_FLAGS
beset effort attempt to remedy warnings
removed unused param names in hex_log baseclass methods due to multitude of unused-warnings
