perf tools: Remove hists from evsel
...
Now tools that deals want to have an hists per evsel need to call
hists__init() before creating any evsels, which can be as early as when
parsing the command line, so do it before calling parse_options().
The current tools using hists/hist_entries are report, top and annotate,
change them to request per evsel hists.
This is in preparation for making evsels usable by 3rd party tools, that
not necessarily live in perf's source code repository.

perf tools: Check recorded kernel version when finding vmlinux
...
Currently vmlinux_path__init() only tries to find vmlinux file from
current directory, /boot and some canonical directories with version
number of the running kernel. This can be a problem when reporting old
data recorded on a kernel version not running currently.
We can use --symfs option for this but it's annoying for user to do it
always. As we already have the info in the perf.data file, it can be
changed to use it for the search automatically.
Before:
$ perf report
...
# Samples: 4K of event 'cpu-clock'
# Event count (approx.): 1067250000
#
# Overhead Command Shared Object Symbol
# ........ .......... ................. ..............................
71.87% swapper [kernel.kallsyms] [k] recover_probed_instruction
After:
# Overhead Command Shared Object Symbol
# ........ .......... ................. ....................
71.87% swapper [kernel.kallsyms] [k] native_safe_halt
This requires to change signature of symbol__init() to receive struct
perf_session_env *.

perf top: Convert to hist_entry_iter
...
Reuse hist_entry_iter__add() function to share the similar code with
perf report. Note that it needs to be called with hists.lock so tweak
some internal functions not to deadlock or hold the lock too long.

perf hists: Check if accumulated when adding a hist entry
...
To support callchain accumulation, @entry should be recognized if it's
accumulated or not when add_hist_entry() called. The period of an
accumulated entry should be added to ->stat_acc but not ->stat. Add
@sample_self arg for that.
