Currently the parsers objects (bison/flex related) are each time perf
is built. No matter the generated files are already in place, the
parser generation is executed every time.

Changing the rules to have proper flex/bison objects generation
dependencies.

The parsers code is not rebuilt until the flex/bison source files
are touched. Also when flex/bison source is changed, only dependent
objects are rebuilt.

Now you can do

$ make tools/<toolname>

from the toplevel kernel directory and have the respective tool built.

If you want to build and install it, do

$ make tools/<toolname>_install

$ make tools/<toolname>_clean

should clean the respective tool directories.

If you want to clean all in tools, simply do

$ make tools/clean

Also, if you want to get what the possible targets are, simply calling

$ make tools/

should give you the short help.

$ make tools/install

installs all tools, of course. Doh.

This patch prints the number of samples and the count of performance
events separately.

This allows comparing performance of different applications with each
other.

Previously, the sample count was displayed against an 'Events:' heading.
With this patch, the header now reads (for example):

Samples: 5K of event 'instructions'
Event count (approx.): 2993026545

     2f:       jne    ffffffff81265494 <__list_del_entry+0x84>
<SNIP>
     84:       mov    %rdi,%rcx

The offset view will be the default as soon as operations that deal with
offsets in a function are handled accodringly, i.e. in offset view the
above will become:

     2f:       jne    __list_del_entry+0x84
<SNIP>
     84:       mov    %rdi,%rcx

And then a follow up patch will allow navigating thru jumps, just like
we handle callq instructions.

And by default use "magenta" for it.

Both the --stdio and --tui routines follow the same semantics.

Tools that want to change parts of the line to a different color and
then restore the previous one will use this, starting with the annotate
browser that will change the color of addresses if not on the current
entry, i.e. the selected one.

This routine was checking only if the provided address was after
sym->end, not if it was before sym->start.

Fix that by checking for both and return in both cases -ERANGE, so that
tools can communicate this to the user properly, or if they chose so, to
abort.

This problem was reported previously but the fixes involved either doing
what was being done for the > end case, i.e. silently drop the sample,
returning 0, or aborting at this function, which is in a lib (or better,
is slated to be at some point) and shouldn't abort.

The 'report' tool already checks this value and uses pr_debug to warn
the user.

This patch makes the 'top' tool check it too and warn once per map where
such range problem takes place.

If there's an event with no samples in data file, the perf report
command can segfault after entering the event details menu.

Following steps reproduce the issue:

 # ./perf record -e syscalls:sys_enter_kexec_load,syscalls:sys_enter_mmap ls
 # ./perf report
 # enter '0 syscalls:sys_enter_kexec_load' menu
 # pres ENTER twice

Above steps are valid assuming ls wont run kexec.. ;)

The check for sellection to be NULL is missing. The fix makes sure it's
being check. Above steps now endup with menu being displayed allowing
'Exit' as the only option.

When a process exec()'s, all the maps are retired, but we keep the hist
entries around which hold references to those outdated maps.

If the same library gets mapped in for which we have hist entries, a new
map will be created.  But when we take a perf entry hit within that map,
we'll find the existing hist entry with the older map.

This causes symbol translations to be done incorrectly.  For example,
the perf entry processing will lookup the correct uptodate map entry and
use that to calculate the symbol and DSO relative address.  But later
when we update the histogram we'll translate the address using the
outdated map file instead leading to conditions such as out-of-range
offsets in symbol__inc_addr_samples().

Therefore, update the map of the hist_entry dynamically at lookup/
creation time.

We were only decaying the entries for the offsets that were associated
with an objdump line.

That way, when we accrued the whole instruction addr range, more than
100% was appearing in some cases in the live annotation TUI.

Fix it by not traversing the source code line at all, just iterate thru
the complete addr range decaying each one.
