perf script: Add callchain to generic and tracepoint events ... This provides valuable information for tracing performance problems. Since this change alters the interface for the python scripts, also adjust the script generation and the provided scripts.

perf: net_dropmonitor: Remove progress indicator ... We can read /proc/kallsyms in a fraction of a second, so why waste a further fraction of a second showing progress?

perf: net_dropmonitor: Do not assume ordering of dictionaries ... The sort order of dictionaries in Python is undocumented. Use tuples instead, which are documented to be lexically ordered.

perf: net_dropmonitor: Fix symbol-relative addresses ... The comparison between traced and symbol addresses is backwards: if the traced address doesn't exactly match a symbol (which we don't expect it to), we'll show the next symbol and the offset to it, whereas we should show the previous symbol and the offset from it.

perf: net_dropmonitor: Fix trace parameter order ... This works much better if we don't treat protocol numbers as addresses.

perf script: Add drop monitor script ... A while back I created the dropmonitor protocol, which allowed users to get reports of dropped frames communicated to them via a netlink socket. While useful, several people have now asked that I integrate the ability to do drop monitoring with perf, so they don't have to run additional tools. This patch adds a drop monitor script to the perf suite, and provides the same output that the netlink socket does.
