  Module: Debugger interface.
  Comments:
  It implements the interface with the debugger.

  TODO:
  The most important unimplemented features and unsolved things are:


-----------------------------------------------
Low priority:

General:
* Some stop mechanism to avoid waiting for response time out.
* Some way to revert the "don't show next time" options. Like with the
advices. It means we must concentrate them into one place.
* Mechanism to select a PID from the running processes.

Breakpoints:
* Detect recompilation of the target from "outside", that's without using Run
program. A good moment could be when we are restarting. In this case move the
breakpoints.
* Right click on a line where we have a bkpt should offer to edit it.
* When adding a new breakpoint from the dialog use the current file and
function to field the empty fields.

Inspectors:
* Highlight changed values.
* Add "graphic lines" to the tree.
* Mouse click to un/fold sections.

Watches:
* Highlight changed values.

Data Window:
* Small dialog with all the modes.
* Mouse movement.
* Configure the max length (same warning).
* Things ML had:
 - search(-next,-prev) ^S ^N ^P
 - bookmarks?
 - try to fix 32-bit dependencies
 - change address types to correct types using libgdb.h

Debug Window:
* Save content to disk.

Disassembler Window:
* Keys or similar to change the size used by the registers and the code.
* Some, slow, way to choose the format for the registers. It will imply
fetching its values by batchs with the same format.
* Support syntax hl. for other CPUs.
* The "code" created is pure UNIX \n text, but what about DOS files with
\r\n? (I mean source C/C++ files mixed with asm code).
* Option to avoid the "auto open" (current behavior)

by Function:
void TSetEditorApp::DebugFinishFun()
void TSetEditorApp::DebugReturnNow() (same?)
 Should we check if we are at main? Not sure, the check is expensive:
1) Get the list of frames, 2) Determine if we are at the top, 3) Release the
frames. First time I got the gdb error I got confused, but is quite obvious.

void TSetEditorApp::DebugCallStack()
should I modify mi lib to return something better ...
Move the code to the "parser.c" in migdb

int TDisAsmEdWin::jumpToFrame(mi_frames *f)
We should lock the editor until the end, that's annoying because of the
unlocks on fails.

void TInspector::updateVars(mi_gvar_chg *changed)
What if a variable changes its type? I don't know how can it be but gdb code
seems to support it.

int isValidAddress(const char *taddr, unsigned long &addr)
It determines if something is a pointer using a very weak methode.

void TDataViewer::handleEvent(TEvent & event)
It does a complete redraw when 1 char is inserted, it looks like an overkill.

-----------------------------------------------
Whish gdb could:

HAVE LESS BUGS!!!!

Eval/Modify:
* Set the format for results, currently you must inspect the variable to do it.

Disassembler Window:
* Choose the format for registers individualy, not for all.
* Avoid reporting wrong functions. Like when I stop during a getchar and it says
it was executing read but the read symbol is 800 KB away from the real address.


IMPORTANT NOTES!!!

1) Breakpoints are very tied to splines. Splines associate an *absolute*
file name with some lines. But breakpoints usually are specified as
*relative* file names. It means that when we search for a breakpoint using
its name we must expand it. Is gdb the one in charge to keep its name
relative because we always send to gdb absolute file names.

2) Path for sources and similar details.
GDB is smart if we compile using absolute paths. But is quite idiot if we
don't. Specially the one from Debian GNU/Linux Woody (2002-04-01-cvs).
Is quite bizarre that:
 -break-insert /full-path/file.cc:line
 -> file="file.cc"
But latter says that /full-path/file.cc isn't in the symtab.
The CLI dir command or MI -environment-directory seems to solve the
problems. Currently after connecting I'm sending to gdb a list of
directories to look for sources.

3) When gdb stops in a function inside a library (no debug info) the
reported function can be bogus. In my tests with getchar it says we stopped
in read (when sending a sigint or attaching), but read is 800 KB away in
another library. So in the middle we have a gap with unaccessable memory. So
when we ask gdb to disassemble read we cross the gap and gdb dies. Here I see
two bugs: 1) Wrong function name and 2) Crashing just because reading
unaccessable memory.

  Watches Window

  "~W~atch an expression"

  I first implemented the "variable objects" mechanism provided by gdb
(according to docs that's what Cygnus' Insight uses). But the way it works is
confusing, specially for RHIDE users. So I added watches that works like the
ones found in RHIDE and they are the "normal".
  As the "v.o." mechanism takes care of the scope I named them "with scope".
  For long lists the "with scope" watches should be faster because we know
which ones changed and we don't evaluate all.
