T2345: Replace instances of NULL with nullptr
The following changes have been applied to src and lib folders: regex replace: ([^"_])NULL ⇒ \1nullptr (8968 chgs in src, 1153 in lib) Manually find/change: (void \*) nullptr ⇒ nullptr (1 case) regex find: ".*?nullptr.*?" Manually ~14 cases back to "NULL" in src, ~2 in lib regex finds a few false positive where nullptr appears between two strings in a function call
