Enable users capturing larger traces or traces of larger workloads to specify a buffer size to perf_events.
Adds -buffersize argument that takes a value of the following format:
A number of pages.
A number of bytes, kilobytes, megabytes, or gigabytes by using the suffix B, K, M, or G accordingly.
Example usages include:
-buffersize 20: 20 pages
-buffersize 100M: 100 megabytes
Note: perf will convert the value to a number of pages, and then round up to the nearest power of 2. Thus, we shouldn't see a smaller buffer size, but we may see a larger size than requested.
