perf tools: Factorize high level dso helpers 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.

perf report: Implement initial UI using newt 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.

perf tools: Fix TUI helpline output In commit e2f4351 "perf ui/helpline: Introduce ui_helpline__vshow()" the test for the browser used made ui_helpline__vshow() to be called only for the GTK browser. The TUI one then was not used and vfprintf(stderr, ...) was used instead, making the TUI scroll the screen instead of just printing on the last line. Fix it by doing the proper check, that is to call ui_helpline__vshow to be called for both the TUI and GTK browsers.
