2022-10-09Remove extern from function declared in headers. (#13790)vkalintiris
By default functions are declared as extern in C/C++ headers. The goal of this PR is to reduce the wall of text that many headers have and, more importantly, to make the declaration of extern'd variables - of which we have many dispersed in various places - easily and quickly identifiable. Automatically generated with: $ git grep -l '^extern.*(' '**.h' | \ grep -v libjudy | \ grep -v 'sqlite3.h' | \ xargs sed -i -e 's/extern \(.*(.*$\)/\1/' This is a NFC.
