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.

<title>perf scripts: Fallback to syscalls:* when raw_syscalls:* is not available</title>

<content type='text'>
Older kernels (e.g., RHEL6) do system call tracing via the
syscalls:sys_{enter,exit} tracepoints rather than using raw_syscalls:*.

Update perf python and perl scripts to fallback to syscalls:* when
raw_syscalls:* isn't available.

They convey no information, perhaps I was bitten by some snake at some
point, complete the detox by naming the last of those arguments more
sensibly.

765532c8 (perf script: Finish the rename from trace to script,
2010-12-23) made a mistake during find-and-replace replacing
"../../../util/trace-event.h" with "../../../util/script-event.h", a
non-existent file.  Fix this include.

We can read /proc/kallsyms in a fraction of a second, so why waste
a further fraction of a second showing progress?

The sort order of dictionaries in Python is undocumented.  Use
tuples instead, which are documented to be lexically ordered.

<content type='text'>
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.

This works much better if we don't treat protocol numbers as addresses.

<title>perf perl scripts: Fix SIGALRM and pipe read race for rwtop</title>

<id>urn:sha1:b22e79395c0fe4c86dd35745a929366034386ccc</id>
<content type='text'>
Fixing rwtop script race. The issue is caused by rwtop script triggering
SIGALRM and underneath pipe reading layer reporting error when
interrupted.

Fixing this by setting SA_RESTART for rwtop SIGALRM handler, which
avoids interruption of the pipe reading layer.

The discussion for this issue &amp; fix is here:
