[PATCH 3/9] implement ends_with via strip_suffix
From: Jeff King <hidden>

The ends_with function is essentially a simplified version
of strip_suffix, in which we throw away the stripped length.
Implementing it as an inline on top of strip_suffix has two
advantages:
1. We save a bit of duplicated code.
2. The suffix is typically a string literal, and we call
strlen on it. By making the function inline, many
compilers can replace the strlen call with a constant.
