As a convenience, equivalent to pressing Enter in a line with a kernel
symbol and then selecting "Zoom" into the kernel DSO.

Taking into account the current status of the callchain, i.e. if folded,
show "Expand", otherwise "Collapse", also show the name of the entry
that will be affected and mention the hotkeys for expanding/collapsing
all callchains below the main entry, the one that appears with/without
callchains.

Since previously pressing ENTER toggled expansion/collapse of callchain
entries and now brings up the same menu used when callchains are not
present, add an entry so that users can quickly figure out the change in
behaviour.
Its worth mentioning that we also always had 'e'/'c' to expand/collapse
all entries in a hist entry and 'E'/'C' for all hist entries.

When callchains are present the ENTER key switches from bringing up the
menu that offers Annotation, Zoom by DSO, etc to expanding/collapsing
one callchain level, causing confusion, fix it by making it consistently
bring up the menu and use '+' to expand/collapse one callchain level.
Next patch will also add an entry to the menu to allow
expanding/collapsing, so that people used to ENTER expanding one
callchain level can quickly find it and use it instead.

This patch supports jumping from tui total cycles view to symbol source
view.
For example,
perf record -b ./div
perf report --total-cycles
In total cycles view, we can select one entry and press 'a' or press
ENTER key to jump to symbol source view.
This patch also sets sort_order to NULL in cmd_report() which will use
the default branch sort order. The percent value in new annotate view
will be consistent with the percent in annotate view switched from perf
report (we observed the original percent gap with previous patches).

It would be nice if we could jump to the assembler/source view (like the
normal perf report) from total cycles view.
This patch moves the block_hists_tui_browse from block-info.c to
ui/browsers/hists.c in order to reuse some browser codes (i.e
do_annotate) for implementing new annotation view.

So that we pass that substructure around and with it consolidate lots of
functions that receive a (map, symbol) pair and now can receive just a
'struct map_symbol' pointer.
This further paves the way to add 'struct map_groups' to 'struct
map_symbol' so that we can have all we need for annotation so that we
can ditch 'struct map'->groups, i.e. have the map_groups pointer in a
more central place, avoiding the pointer in the 'struct map' that have
tons of instances.

'symbol' pointers
We are already passing things like:
symbol__annotate(ms->sym, ms->map, ...)
So shorten the signature of such functions to receive the 'map_symbol'
pointer.
This also paves the way to having the 'struct map_groups' pointer in the
'struct map_symbol' so that we can get rid of 'struct map'->groups.

1. Since we have used use_browser in report__browse_block_hists
to support stdio mode, now we also add supporting for tui.
2. Move block tui browser code from ui/browsers/hists.c
to block-info.c.
v6:
---
Create report__tui_browse_block_hists in block-info.c
(codes are moved from builtin-report.c).
v5:
---
Fix a crash issue when running perf report without
'--total-cycles'. The issue is because the internal flag
is renamed from 'total_cycles' to 'total_cycles_mode' in
previous patch but this patch still uses 'total_cycles'
to check if the '--total-cycles' option is enabled, which
causes the code to be inconsistent.
v4:
---
Since the block collection is moved out of printing in
previous patch, this patch is updated accordingly for
tui supporting.
v3:
---
Minor change since the function name is changed:
block_total_cycles_percent -> block_info__total_cycles_percent

Pruning a bit more the includes dependency tree. Building this thing on
lots of containers takes time, we better reduce the time per build, each
container is doing 6 builds when clang and clang-devel are available,
and the plan is to do a 'make -C tools/perf build-test' that have many
more.
Also helps when doing normal development, as touching some random file
will have a much reduced chance of triggering lots of rebuilds.

In places where the equivalent was already being done, i.e.:
free(a);
a = NULL;
And in placs where struct members are being freed so that if we have
some erroneous reference to its struct, then accesses to freed members
will result in segfaults, which we can detect faster than use after free
to areas that may still have something seemingly valid.

We got the sane_ctype.h headers from git and kept using it so far, but
since that code originally came from the kernel sources to the git
sources, perhaps its better to just use the one in the kernel, so that
we can leverage tools/perf/check_headers.sh to be notified when our copy
gets out of sync, i.e. when fixes or goodies are added to the code we've
copied.
This will help with things like tools/lib/string.c where we want to have
more things in common with the kernel, such as strim(), skip_spaces(),
etc so as to go on removing the things that we have in tools/perf/util/
and instead using the code in the kernel, indirectly and removing things
like EXPORT_SYMBOL(), etc, getting notified when fixes and improvements
are made to the original code.
Hopefully this also should help with reducing the difference of code
hosted in tools/ to the one in the kernel proper.

initialization
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.

Fix the argv ui browser code to correctly display more entries than fit
on the screen without crashing. The problem was some type confusion with
pointer types in the ->seek function. Do the argv arithmetic correctly
with char ** pointers. Also add some asserts to find overruns and limit
the display function correctly.
Then finally remove a workaround for this in the res sample browser.
Committer testing:
1) Resize the x terminal to have just some 5 lines
2) Use 'perf report --samples 1' to activate the sample browser options
in the menu
3) Press ENTER, this will cause the crash:
# perf report --samples 1

Now 'perf report' can show whole time periods with 'perf script', but
the user still has to find individual samples of interest manually.
It would be expensive and complicated to search for the right samples in
the whole perf file. Typically users only need to look at a small number
of samples for useful analysis.
Also the full scripts tend to show samples of all CPUs and all threads
mixed up, which can be very confusing on larger systems.
Add a new --samples option to save a small random number of samples per
hist entry.
Use a reservoir sample technique to select a representatve number of
samples.
Then allow browsing the samples using 'perf script' as part of the hist
entry context menu. This automatically adds the right filters, so only
the thread or cpu of the sample is displayed. Then we use less' search
functionality to directly jump the to the time stamp of the selected
sample.
It uses different menus for assembler and source display. Assembler
needs xed installed and source needs debuginfo.
Currently it only supports as many samples as fit on the screen due to
some limitations in the slang ui code.

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.
