enlarging font
Fix the following error if shrink / enlarge font is used with the help
window.
Traceback (most recent call last):
File "tools/perf/scripts/python/exported-sql-viewer.py", line 2791, in ShrinkFont
ShrinkFont(win.view)
AttributeError: 'HelpWindow' object has no attribute 'view'
Committer testing:
Before, matches above output:
$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db
Traceback (most recent call last):
File "/home/acme/libexec/perf-core/scripts/python/exported-sql-viewer.py", line 2780, in EnlargeFont
EnlargeFont(win.view)
AttributeError: 'HelpWindow' object has no attribute 'view'
$
After:
No more tracebacks, but the fonts don't get enlarged, which is kinda
frustrating...

As preparation for adding support for copying to clipboard, create view
in TreeWindowBase instead of derived classes.
Committer testing:
Tested using an old .db used to test some older patches:
$ python ~acme/libexec/perf-core/scripts/python/exported-sql-viewer.py ~/c/adrian.hunter/simple-retpoline.db
Nothing breaks.

The compiler might optimize a call/ret combination by making it a jmp.
However the thread-stack does not presently cater for that, so that such
control flow is not visible in the call graph. Make it visible by
recording on the stack a branch to the start of a different symbol.
Note, that means when a ret pops the stack, all jmps must be popped off
first.
Example:
$ cat jmp-to-fn.c
__attribute__((noinline)) int bar(void)
{
return -1;
}
__attribute__((noinline)) int foo(void)
{
return bar() + 1;
}
int main()
{
return foo();

Committer testing:
Install the python2-pyside package, then select these menu options
on the GUI:
"Reports"
"Context sensitive callgraphs"
Then go on expanding the symbols, to get, full picture when doing this
on a fedora:29 with gcc version 8.2.1 20181215 (Red Hat 8.2.1-6) (GCC):
jmp-to-fn
PID:TID
_start (ld-2.28.so)
__libc_start_main
main
foo
bar
To verify that indeed, this fixes the problem.

The scripts in scripts/python are intended to be run from 'perf script'
and the Python version used is dictated by how perf was built (PYTHON=).
Also most distros follow pep-0394 which recommends that /usr/bin/python
refer to Python2 and so may not exist on the system (if PYTHON=python3).
- Remove the explicit shebang
- Install the scripts as mode 644

re-ordered
Table rows can be re-ordered by selecting a column to sort by. After
re-ordering, the "find" operation was highlighting the wrong row, fix
it.

Add a window to display help. It is also possible to display the help
only, by using the option "--help-only" instead of a database name.

Fetching data from the database can be slow. Add a report that provides
the ability to select a subset of branches.

/usr/local/lib/libxed.so
Fall back to /usr/local/lib/libxed.so to cater for distributions that do
not have /usr/local/lib in the library path by default.

Add a report to display branches in a similar fashion to perf script. The
main purpose of this report is to display disassembly, however, presently,
the only supported disassembler is Intel XED, and additionally the object
code must be present in perf build ID cache.
To use Intel XED, libxed.so must be present. To build and install
libxed.so:
git clone https://github.com/intelxed/mbuild.git mbuild
git clone https://github.com/intelxed/xed
cd xed
./mfile.py --share
sudo ./mfile.py --prefix=/usr/local install
sudo ldconfig
