perf tools: Add new perf_atoll() function to parse string representing size in bytes
This patch modifies util/string.[ch] to add new function:
perf_atoll() to parse string representing size in bytes.
This function parses (\d+)(b|B|kb|KB|mb|MB|gb|GB) (e.g. "256MB")
and returns its numeric value. (e.g. 268435456)
