[PATCH 00/13] perf tools: bpf: Improve BPF program ability

[Wang Nan <wangnan0@huawei.com>]

Resend patch set in [1] with sereval improvements based on Arnaldo's
suggestions. This patch set is based on Arnaldo's perf/core.

Patch 1/13 - 2/13 should have already been collected by Arnaldo but
I can't find them in his repository, so I resend them.

Patch 3/13 - 6/13 are improved according to Arnaldo's suggestion: Some
lines are made compat, return values of strdup() are checked, use
named initializers. In addition, error messages are improved to reduce
confusion.

Patch 7/13 - 13/13 are identical to previous version, only cc-lists are
shrinked.
