Replace repeating '==' in documentation with a single one

* README: Replace sequences of repeating '==' identifying section
titles (which is also used by git-apply) with two '=' symbols at the
beginning and at the end of each title.
* TODO: Likewise.
* ChangeLog: Likewise.
* src/atomic_ops/sysdeps/gcc/arm.h: Break a sequence of repeating '=='
(in a comment) with a space.
