strbuf: introduce starts_with() and ends_with()
prefixcmp() and suffixcmp() share the common "cmp" suffix that
typically are used to name functions that can be used for ordering,
but they can't, because they are not antisymmetric:
prefixcmp("foo", "foobar") < 0
prefixcmp("foobar", "foo") == 0
We in fact do not use these functions for ordering. Replace them
with functions that just check for equality.
Add starts_with() and end_with() that will be used to replace
prefixcmp() and suffixcmp(), respectively, as the first step. These
are named after corresponding functions/methods in programming
languages, like Java, Python and Ruby.
In vcs-svn/fast_export.c, there was already an ends_with() function
that did the same thing. Let's use the new one instead while at it.
