Just provide wrappers for things like ui__warning, ui__dialog_yesno and
if they return K_RESIZE, refresh dimensions, redraw the entries, etc.

We have to deal with the TUI mode in perf top, so that we don't end up
with a garbled screen when, say, a non root user on a machine with a
paranoid setting (the default) tries to use 'perf top'.
Introduce a ui__warning_paranoid() routine shared by top and record that
tells the user the valid values for /proc/sys/kernel/perf_event_paranoid.

And move the event_t methods to the perf_event__ too.
No code changes, just namespace consistency.

Fix it by explaining what can be happening and giving the number of processed
and lost events.
Also holler if unknown events were found, that can be due to processing a
perf.data file collected using a newer tool where newer events got added on
reporting using an older perf tool, that or a bug, so ask for a report to be
made.
Works on both --tui and --stdio.

The loop counter math in trace_event was much more complicated than
necessary, resulting in incorrectly decoding the human-readable
portion of the partial last line of hexdump in "perf trace -D" output:
. 0020: 00 00 00 00 00 00 00 00 2f 73 62 69 6e 2f 69 6e ......../sbin/i
. 0030: 69 74 00 00 00 00 00 00 /sbin/i
With this fixed (and simpler!) code, we get the correct output:
. 0020: 00 00 00 00 00 00 00 00 2f 73 62 69 6e 2f 69 6e ......../sbin/in
. 0030: 69 74 00 00 00 00 00 00 it......

When we moved to using ~/.perfconfig to set the value of use_browser,
it changed from a boolean to an int so that the convention used for
use_pager was followed.
That convention is:
-1: unspecified, that is what use_{browser,pager} is initialized
0: Don't use the browser (should be TUI), because was explicitely
set to 0/off/false on ~/.perfconfig [tui] cmd =, or because
we're redirecting the stdout to a file or piping it to some
other command (!isatty()).
1: Use the TUI
Some code was not properly audited and continued testing it as a
boolean, this seems to be the last one.

OPT_INCR()
Parsing an option from the command line with OPT_BOOLEAN on a
bool data type would not work on a big-endian machine due to the
manner in which the boolean was being cast into an int and
incremented. For example, running 'perf probe --list' on a
PowerPC machine would fail to properly set the list_events bool
and would therefore print out the usage information and
terminate.
This patch makes OPT_BOOLEAN work as expected with a bool
datatype. For cases where the original OPT_BOOLEAN was
intentionally being used to increment an int each time it was
passed in on the command line, this patch introduces OPT_INCR
with the old behaviour of OPT_BOOLEAN (the verbose variable is
currently the only such example of this).
I have reviewed every use of OPT_BOOLEAN to verify that a true
C99 bool was passed. Where integers were used, I verified that
they were only being used for boolean logic and changed them to
bools to ensure that they would not be mistakenly used as ints.
The major exception was the verbose variable which now uses
OPT_INCR instead of OPT_BOOLEAN.

Newt has widespread availability and provides a rather simple
API as can be seen by the size of this patch.
The work needed to support it will benefit other frontends too.
In this initial patch it just checks if the output is a tty, if
not it falls back to the previous behaviour, also if
newt-devel/libnewt-dev is not installed the previous behaviour
is maintaned.
Pressing enter on a symbol will annotate it, ESC in the
annotation window will return to the report symbol list.
More work will be done to remove the special casing in
color_fprintf, stop using fmemopen/FILE in the printing of
hist_entries, etc.
Also the annotation doesn't need to be done via spawning "perf
annotate" and then browsing its output, we can do better by
calling directly the builtin-annotate.c functions, that would
then be moved to tools/perf/util/annotate.c and shared with perf
top, etc
But lets go by baby steps, this patch already improves perf
usability by allowing to quickly do annotations on symbols from
the report screen and provides a first experimentation with
libnewt/TUI integration of tools.
Tested on RHEL5 and Fedora12 X86_64 and on Debian PARISC64 to
browse a perf.data file collected on a Fedora12 x86_64 box.

We were using eprintf in some places, that looks at a global
'verbose' level, and at other places passing a 'v' parameter to
specify the verbosity level, unify it by introducing
pr_{err,warning,debug,etc}, just like in the kernel.

Librarize trace_event() helper so that perf trace can use it
too. Also clean up the debug.h includes a bit.
It's not good to have it included in perf.h because it doesn't
make it flexible against other headers it may need (headers
that can also depend on perf.h and then create a recursive
header dependency).

We have two users of dprintf: report and annotate. Another one
is coming with perf trace. Then factorize it into the debug
file.
While at it, rename dprintf() to dump_printf() so that it
doesn't conflicts with its libc homograph.

Factorize multiple definitions of high level dso helpers into the
symbol source file.
The side effect is a general export of the verbose and eprintf
debugging helpers into a new file dedicated to debugging purposes.
