Hafiz Abid Qadeer e73e82f2be Fix multiple problems of lldb-mi blocking on input monitoring and needing a return.
Summary:
One of the problem is reported here.
http://llvm.org/bugs/show_bug.cgi?id=22411

A fix was committed for this problem that works only for OSX. This revision
extends that fix to other system. The select system call has some limitation with
multi-threaded application which have been addresses here.

LLDB-mi exits if quit command is given but needs an extra retur if -gdb-exit is
given. That issue has also been addressed.

Hafiz Abid Qadeer dc0e4915b0 Fix test case for data-disassemble instruction in lldb-mi.
Previously the offset field showed the offset from the section base.
I have fixed it so that first disassembled instruction has offset of 0.
Also made a little modification in the test case to match the output coming
form the lldb-mi.

Hafiz Abid Qadeer 93ad6b31ec Fix a handling of full path in break-insert.
For some time, eclipse (CDT) uses full path of the file in break-insert command
when putting breakpoint on a source line. On windows, a typical command looks
like the following.
56-break-insert -f F:\\work\\ws\\test\\main.c:49

Current implementation in lldb-mi have problem in 2 ways.
1. It was assuming that there will be only one : in the path which is wrong if full
path is supplied.
2. CDT sends out path with double backslashes in windows which gives error on 
resolution.

Fixed the : issue in lldb-mi. Changed FileSpec::Normalize to make sure that it
handles the path with \\ correctly. Added test cases to check for full path in
both lldb-mi and lldb. Also added a test case to check SBFileSpec with double
slashes.

Ilia K 761a7a4b67 Fix evaluation commands (MI)
Summary:
These changes include:
* Fix -var-create to be able use current frame '*' (MI)
* Fix print-values option in -var-update (MI)
* Fix 'variable doesn't exist' error in -var-show-attributes (MI)
* Mark print-values option as 'handled-by-cmd' in -var-update (MI)
* Fix SBValue::GetValueDidChange if value was changed
* Fix lldb-mi: -data-evaluate-expression shows undef vars. Before this fix -data-evaluate-expression perceives undefined variables as strings:
```
(gdb)
-data-evaluate-expression undef
^done,value="undef"
```
* Minor fix: -data-evaluate-expression uses IsUnknownValue()
* Enable MiEvaluateTestCase test

All test pass on OS X.

Hafiz Abid Qadeer 94e222f943 Fix a typo.
The member m_nTimes is used in rest of lldb-mi to represent hit count.
In one place, it was assigned a wrong value (number of locations). This
resulted in lldb-mi showing a hit count of variable 1 when it was created.

Committed as obvious.

Hafiz Abid Qadeer d1f606ff0f Fix a race condition in lldb-mi.
lldb-mi has 3 threads.
1. One that waits for user intput.
2. Another waits for 1st thread to get input command.
3. Waits for events from lldb.

2 & 3 needs to be synchronized so that they don't end up
doing things at same time. For example, while "break insert" is
processing, we can get a breakpoint event. Depending on where we
are in "break-insert", it can have different behavior. In some
cases, it can cause breakpoint to be deleted too. I have added a 
mutex so that command processing and event processing are done 
exclusively and they are not running at the same time.

In longer term, I think thread 2 & 3 should be merged to be only 
one thread which can wait on command or events.

Hafiz Abid Qadeer 9a0d572750 Restore the signal handler for Windows as it is not presistent there.
On windows, signal handler is reset to default once a signal is received. 
This causes doing ctrl-c twice on console (or pressing suspend button twice
in eclipse ide which uses SIGINT to stop the debuggee) to crash lldb-mi on 
windows. Although there is very tiny window (after signal handler is called
and before we restore the handler) where default handler will be in place.
But this is hardly a problem in practice as IDEs generally disable their suspend
button once it has been presses.

Hafiz Abid Qadeer 0d51c1563b Fix CLI commands in lldb-mi.
This patch fixes execution of CLI commands in MI mode. The CLI commands are 
executed using "-interpreter-exec" command. The bug was in the 
CMICmnLLDBDebugSessionInfo class which contained the following members: 
SBProcess, SBTarget, SBDebugger and SBListener, but CLI commands don't affect
them and they aren't updated. Therefore some members can contain incorrect 
(or obsolete) reference and it can cause an error. My patch removes these 
members and uses getters that provides the updated instance every time it is used.

Patch from Ilia K ki.stfu@gmail.com. Approved by Greg.

Hafiz Abid Qadeer 6a4ea636f3 Fix log file generation in lldb-mi.
When it runs, lldb-mi creates a log file. There is an option --noLog
to disable the creation but it does not work and you end up with log 
file. This happens as log is enabled in a few places in the code 
although it has been disabled by this option.

This commit tried to fix the problem in the following way.

Log file generation is disabled by default.
You can enable it by giving --log option. It is the only way to enable
it. Rest of the call have been removed.

So the code basically remove the calls that enable the log 
unconditionally and changes the option --noLog to --log.

Hafiz Abid Qadeer fcbc3cdf3c Replace ioctl with select to reduce processor usage by lldb-mi on OSX.
This saga started with a hang on OSX. 2 solutions were proposed.
1) 'select' based solution works ok on OSX but slows down test completion time
on Linux many times.
2) 'ioctl' base solution also works but it causes heavy processor usage on OSX
as reported by Ilia K.

But as the original hang did not occur on Linux so this commit re-introduces the
'select' in conditional code so that it only runs for OSX. There is no need for
this 'fix' to run on Linux.

Initial patch by Ilia K <ki.stfu@gmail.com>. A few changes were made by me.

bug. Also added test case for -stack-list-local and -stack-list_arguments.
