Subject: [PATCH] Remove compare of global array tagsByName to NULL

A 2016 change (57a96d2486c26142ebb168a1f00b0374d35bf044) apparently
changed tagsByName from dynamic allocation to being static, so that
Valgrind would not complain about lost memory. The definition is:

    static headerTagTableEntry tagsByName[TABLESIZE];

But a comparison was left of `tagsByName == NULL` in lib/tagname.c
and compiling with clang gives a warning, saying it is never NULL.
