grapher: remove _zoomFactor from horizontal scaling calculation
This makes zooming more consistent and less buggy.
* grapher/Graph.cxx (Graph::draw): Set graph time spread using
_zoomFactor.
* grapher/Graph.hxx (Graph::getHorizontalScale): no _zoomFactor
* grapher/GraphWidget.cxx (on_motion_notify_event): Dragging increment
uses _zoomFactor.
(on_scroll_event): Set extents after changing the zoom factor with
the scroll wheel.

grapher: scale from right end of graph
The right side of the graph represents the most recent time. Since
there is never anything interesting to the right of that, it makes
sense to have the origin of the scaling be there.
* grapher/Graph.hxx (getHorizontalScale): new function
* grapher/GraphStyle.cxx (GraphStyleBar::draw, GraphStyleDot::draw,
GraphStyleEvent::draw): Use cairo transform functions to set up
scaling.
(GraphStyleBar::dataIndexAtPoint, GraphStyleEvent::dataIndexAtPoint):
Base calculations on scaling from right.

grapher: fix bug in looking up event under pointer
I don't why I thought this ever worked.
* grapher/GraphStyle.cxx (GraphStyleEvent::dataIndexAtPoint): return
distance from beginning of buffer, not beginning of search bounds.

don't assume buffer passed to pty_write is null terminated
* testsuite/systemtap.examples/general/grapher.stp: Use kernel_char
instead of kernel_string to dig characters out of buffer.
commit 4c18e89e50f274dd905876f725eb1cf98ad6b2df

Date: Tue Dec 22 12:00:41 2009 +0100
grapher: draw axes on multiples of the axis "major unit"
* grapher/Graph.cxx (Graph::draw): Make axis values end up on
multiples of majorUnit.

grapher: scroll continuously with time
Don't scale graph based on how much data will fit. This didn't work
very well and resulted in distracting, weird scale changes. We now
assume that scripts output their time (x axis) in milliseconds.
* grapher/Graph.hxx (setCurrentTime): New function.
* grapher/Graph.cxx (Graph::draw): Assume a fixed default scale of 1
pixel = 5 milliseconds and don't do any autoscaling.
* grapher/GraphWidget.cxx (GraphWidget constructor): Set global time
base on startup.
(on_expose_event): Don't search graphs for earliest time.
* grapher/GraphWidget.hxx (_timeBaseInitialized): delete
* grapher/Time.hxx: new file; interface to timeval.

PR11015 Support shared library reloading (in different processes)
* runtime/task_finder_vma.c (stap_remove_vma_map_info): Return negative
status on failure.
(stap_find_vma_map_info): Likewise.
(stap_find_vma_map_info_user): New function.
(stap_drop_vma_maps): New function.
* runtime/sym.h (addr): Renamed to static_addr, to store addresses for
sections which are always mapped at the same address.
(_stp_module_relocate): Add extra struct task_struct *tsk argument.
* runtime/sym.c (_stp_tf_exec_cb): New callback, calls stap_drop_vma_maps.
(_stp_tf_mmap_cb): Don't store address in module.section, but call
stap_add_vma_map_info() per tsk->group_leader for matched module.
Don't register empty/null modules.
(_stp_module_relocate): Take extra struct task_struct *tsk argument,
cache last tsk used. Only use section->static_addr for none dynamic
modules. Use stap_find_vma_map_info_user() to locate dynamic modules.
(_stp_mod_sec_lookup): Add extra argument unsigned long *rel_addr to
optionally store relative address when module/section found.
(_stp_kallsyms_lookup): Use _stp_mod_sec_lookup to find relative address.
(_stp_sym_init): Register _stp_tf_exec_cb in stap_task_finder_target.
Add error check to see if task finder could be initialized.
* dwflpp.cxx (emit_address): Pass NULL for kernel/modules and current for
user tasks to _stp_module_relocate.
* runtime/transport/symbols.c (_stp_do_relocation): Set new static_addr
_stp_section field.
* runtime/unwind.c (adjustStartLoc): Take new struct task_struct *tsk
argument and pass to stap_find_vma_map_info_user and _stp_module_relocate
to find adjusted addr.
(_stp_search_unwind_hdr): Pass through struct task_struct *tsk.
(unwind_frame): Likewise.
* tapset/context-symbols.stp (probemod): Add NULL to _stp_mod_sec_lookup
call to indicate we aren't interested in relative address.
* tapsets.cxx (dwarf_derived_probe_group::emit_module_init): Pass NULL to
_stp_module_relocate to indicate kernel/module address.
