c46219ac34 perf annotate: Introduce ->free() method in ins_ops 
So that we don't special case disasm_line__free, allowing each
instruction class to provide an specialized destructor, like is needed
for 'lock'.

Ditto for many more instructions that take two operands.

fb29fa58e3 perf annotate: Mark jump instructions with no offset 
I.e. jumps that go to code outside the current function, that is denoted
in objdump -dS as:

   399f877a9f: jne    399f87bcf4 <_L_lock_5154>

I.e. without the + after the name of the current function, like in:

   399f877aa5: jmp    399f877ab2 <_int_free+0x412>

The browser will use that info to avoid drawing connectors to the start
of the function, since ops.target.addr was zero.

This is just a proof of concept and works only on x86_64, more work is

should already be useful as-is.

c97cf42219 perf top: Live TUI Annotation 
Now one has just to press the right key, 'a' or Enter on the main 'perf
top --tui' screen to live annotate the symbol under the cursor.

The annotate window starts centered on the hottest line (the one with
most samples so far) then TAB and shift+TAB can be used to go to the
prev/next hot line.

Pressing 'H' at any point will center again the screen on the hottest
line.

The live annotation done in 'perf top' needs to limit the context before
lines that aren't filtered out by the min percent filter, if we don't do
that, the screen in a tty often is not enough for showing what is
interesting: lines with hits and a few source code lines before it.

symbol that is passed everywhere.

Rename "struct sym_priv" to "struct annotation", etc, to clarify this

Rename "struct sym_ext" to "struct source_line", to give it a meaningful
name, that clarifies that it is a the result of an addr2line call, that
is sorted by percentage one particular source code line appeared in the
annotation.

And since we're moving things around also rename 'sym_hist->ip' to
'sym_hist->addr' as we want to do data structure annotation at some
point.
