Ilia K b2b0170c0e Allow to construct CMIUtilString using std::string directly + cleanup CMIUtilString (MI)
Summary:
Allow to construct CMIUtilString using std::string directly + cleanup CMIUtilString (MI)

This patch cleans up lldb-mi code, and serves to simplify
the following case:
```
  std::string strGoodbye = "!Hello";
  CMIUtilString strHello(strGoodbye.substr(1).c_str());
```

With CMIUtilString(std::string) we can omit .c_str():
```
  std::string strGoodbye = "!Hello";
  CMIUtilString strHello(strGoodbye.substr(1));
```

Also, it removes 2 ctors because they aren't needed:
# CMIUtilString::CMIUtilString(const char *const *vpData)
# CMIUtilString::CMIUtilString(const char *vpData, size_t nLen)
and cleans up CMIUtilString::operator=(const std::string &vrRhs).

Dawn Perchik b01310008f [lldb-mi] Fix the handling of files in -data-info-line and -symbol-list-lines.
This fixes -data-info-line and -symbol-list-lines to parse the filename
and line correctly when line entries don't have the optional column
number and the filename contains a Windows drive letter. It also fixes
-symbol-list-lines when code from header files is generated.

Bruce Mitchener 7dd8c12d84 [lldb-mi] Clean up CMICmdArgSet usage.
Summary:
CMICmdArgSet stores a vector of non-const pointers to the arguments
that it is validating. It owns them and is responsible for deleting
them.

We don't need to pass a const reference to the argument to
CMICmdArgSet::Add and then take the address and const_cast it
when we can just pass the argument pointer in directly.

This lets us remove some noise at every call site for CMICmdArgSet::Add
and then clean up a couple of bits inside CMICmdArgSet to remove
const_casts.

Hafiz Abid Qadeer 8647f4381f Fix -data-evaluate-expression for array.
Summary:
For an array declared like "blk[2][3]", this command was showing:
-data-evaluate-expression blk
^done,value="{[0] = [3], [1] = [3]}"

After this fix, it shows:
-data-evaluate-expression blk
^done,value="{[0] = {[0] = 1, [1] = 2, [2] = 3}, [1] = {[0] = 4, [1] = 5, [2] = 6}}"

The code to do the right thing was already available and used by other commands.
So I have just used that and removed the half-baked previous implementation.

Bruce Mitchener 1425b47773 [LLDB-MI] Properly detect missing mandatory arguments to MI commands
Summary:
Previously if an MI command had **X** mandatory and **Y** optional arguments you could provide **X** or more optional arguments without providing any of the mandatory arguments, and the argument validation code wouldn't complain.

For example this would pass argument validation even though the mandatory **address** and **count** arguments are missing:

-data-read-memory-bytes --thread 1 --frame 0

Part of the problem was that an empty string was considered a valid value for a mandatory argument, which didn't make much sense.

Patch by Vadim Macagon. Thanks!

Test Plan:
./dotest.py -A x86_64 -C clang --executable $BUILDDIR/bin/lldb tools/lldb-mi/

No unexpected failures on my Ubuntu 14.10 64bit Virtualbox VM.

- The -o (offset) option is now properly handled, not just silently ignored.
- The --thread option is now properly handled.
- A new --frame option has been added for consistency with GDB.
- Added a new test to verify old and new functionality.

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.
