Subject: [RFC PATCH 01/77] checks: Use consistent type for strspn() returned value

strspn() returns a size_t value.

The function is called in several places and in all places this value is
stored in a size_t variable except in check_node_name_chars_strict().

Fix the variable type used in check_node_name_chars_strict().
