Currently, the evlist mmap related helpers and APIs accept evlist and idx, and dereference 'struct perf_mmap' by evlist->mmap[idx]. This is unnecessary, and force each evlist contains only one mmap array. Following commits are going to introduce multiple mmap arrays to a evlist. This patch refators these APIs and helpers, introduces functions accept perf_mmap pointer directly. New helpers and APIs are decoupled with perf_evlist, and become perf_mmap functions (so they have perf_mmap prefix). Old functions are reimplemented with new functions. Some of them will be removed in following commits.
