Some compilers will complain when using a member of a struct to
initialize another member, in the same struct initialization.
For instance:
debian:8 Debian clang version 3.5.0-10 (tags/RELEASE_350/final) (based on LLVM 3.5.0)
oraclelinux:7 clang version 3.4.2 (tags/RELEASE_34/dot2-final)
Produce:
ui/browsers/annotate.c:104:12: error: variable 'ops' is uninitialized when used within its own initialization [-Werror,-Wuninitialized]
(!ops.current_entry ||
^~~
1 error generated.
So use an extra variable, initialized just before that struct, to have
the value used in the expressions used to init two of the struct
members.

The scripts menu traditionally only showed custom perf scripts.
Allow to run standard perf script with useful default options too.
- Normal perf script
- perf script with assembler (needs xed installed)
- perf script with source code output (needs debuginfo)
- perf script with custom arguments
Then we automatically select the right options to display the
information in the perf.data file.
For example with -b display branch contexts.
It's not easily possible to check for xed's existence in advance. perf
script usually gives sensible error messages when it's not available.

The annotation line percentage is compared and inserted into the rbtree,
but the percent field of 'struct annotation_data' is an array, the
comparison result between them is the address difference.
This patch compares the right slot of percent array according to
opts->percent_type and makes things right.
The problem can be reproduced by pressing 'H' in perf top annotation view.
It should highlight the instruction line which has the highest sampling
percentage.

We have more current function tto get the title for annotation,
which is hists__scnprintf_title. They both have same output as
far as the annotation's header line goes.
They differ in counting of the nr_samples, hists__scnprintf_title
provides more accurate number based on the setup of the
symbol_conf.filter_relative variable.
Plus it also displays any uid/thread/dso/socket filters/zooms
if there are set any, which annotation__scnprintf_samples_period
does not.

This is not useful only for the TUI, we'll want to somehow mark the
--stdio2 lines with the most jump sources too.
And moving this will allow us to change some function signatures from
annotate_browser to ui_browser, reducing boilerplate.

To reduce the boilerplate to get to the symbol being annotated from the
struct browser ->priv area.

Out of the TUI code, since now all it touches is what is in 'struct
annotation'.

For the TUI, that is interactive, its interesting to have a
configuration that one can go on changing and then when moving from one
symbol annotation to another symbol, the options set while browsing the
first symbol to be kept.
But since we're trying to make this code reusable by a --stdio
formatter, we better have a pointer in struct annotation and in the TUI
case set it to the global, but use something else for other cases, such
as --stdio2.

Out of the TUI code, as it has nothing specific to that UI and should be
used in the other output modes as well.

This is needed to reduce the differences between the TUI mode and the
other annotation UIs, next csets will move that code to the UI-neutral
annotation library. Leaving it in place for now to ease review.

This is to pave the way to have more functions shared between TUI, stdio
and the upcoming stdio2 formatting, that will use the __scnprintf
functions used by --tui in a --stdio fashion.
This partially addresses the comments added in cset 30e863bb6f ("perf
annotate: Compute IPC and basic block cycles"):
/*
* This should probably be in util/annotate.c to share with the tty
* annotate, but right now we need the per byte offsets arrays,
* which are only here.
*/
The following patches will address the rest.

This will be useful when making parts of the TUI browser generic enough
to be used for a new stdio mode, available even when the TUI is not
built in, for explicit user decision or when the necessary library devel
files, for the slang library currently, are not available in the build
system.

This first happened with a gcc function, _cpp_lex_token, that has the
usual jumps:
│1159e6c: ↓ jne 115aa32 <_cpp_lex_token@@Base+0xf92>
I.e. jumps to a label inside that function (_cpp_lex_token), and those
works, but also this kind:
│1159e8b: ↓ jne c469be <cpp_named_operator2name@@Base+0xa72>
I.e. jumps to another function, outside _cpp_lex_token, which are not
being correctly handled generating as a side effect references to
ab->offset[] entries that are set to NULL, so to make this code more
robust, check that here.
A proper fix for will be put in place, looking at the function name
right after the '<' token and probably treating this like a 'call'
instruction.
For now just don't draw the arrow.
