[PATCH v4 4/5] perf callchain: Move callchain option parsing out of builtin

[Ian Rogers <irogers@google.com>]

record_opts__parse_callchain, record_callchain_opt,
record_parse_callchain_opt are shared by builtin-record, builtin-top
and builtin-trace, they are declared in callchain.h. Move the
declarations to callchain.c for consistency with the header.
