69b0488d7a Separated the DWARF index for types from that the index of the namespaces
since we can't parse DW_TAG_namespace DIEs as types. They are only decls in
clang. All of the types we handle right now have both clang "XXXType" classes
to go with the "XXXDecl" classes which means they can be used within the 
lldb_private::Type class. I need to check to see which other decls that don't
have associated type objects need to float around the debugger and possibly
make a lldb_private::Decl class to manage them.

36f3b369d2 Added support for breakpoint conditions. I also had to separate the "run the expression" part of ClangFunction::Execute from the "Gather the expression result" so that in the case of the Breakpoint condition I can move the condition evaluation into the normal thread plan processing.
Also added support for remembering the "last set breakpoint" so that "break modify" will act on the last set breakpoint.

8f92f0a35c Fixed an expression parsing issue where if you were stopped somewhere without
debug information and you evaluated an expression, a crash would occur as a
result of an unchecked pointer.

Added the ability to get the expression path for a ValueObject. For a rectangle
point child "x" the expression path would be something like: "rect.top_left.x".
This will allow GUI and command lines to get ahold of the expression path for
a value object without having to explicitly know about the hierarchy. This
means the ValueObject base class now has a "ValueObject *m_parent;" member.
All ValueObject subclasses now correctly track their lineage and are able
to provide value expression paths as well.

Added a new "--flat" option to the "frame variable" to allow for flat variable
output. An example of the current and new outputs:

(lldb) frame variable 
argc = 1
argv = 0x00007fff5fbffe80
pt = {
  x = 2
  y = 3
}
rect = {
  bottom_left = {
    x = 1
    y = 2
  }
  top_right = {
    x = 3
    y = 4
  }
}
(lldb) frame variable --flat 
argc = 1
argv = 0x00007fff5fbffe80
pt.x = 2
pt.y = 3
rect.bottom_left.x = 1
rect.bottom_left.y = 2
rect.top_right.x = 3
rect.top_right.y = 4


As you can see when there is a lot of hierarchy it can help flatten things out.
Also if you want to use a member in an expression, you can copy the text from
the "--flat" output and not have to piece it together manually. This can help
when you want to use parts of the STL in expressions:

(lldb) frame variable --flat
argc = 1
argv = 0x00007fff5fbffea8
hello_world._M_dataplus._M_p = 0x0000000000000000
(lldb) expr hello_world._M_dataplus._M_p[0] == '\0'

10ad799386 Modify "process handle" so that if no signals are specified it lists/updates them all,
if no update commands are specified it just lists the current values, and show that
it always shows the new values for a signal after it has been updated.  Also updated
the help text to match the new functionality.

c066ab4385 Add an initial version of test that exercise the lldb commands: 'process signal'
and 'process handle'.  The test suite would like to control the asynch/sync
execution of the interpreter during the middle of the test method, so the
CommandInterpreter::SetSynchronous(bool value) is modified to allow the mode to
be changed more than once.

In practice, it would be advisable to control the process and to set the
async/sync mode from a single thread, too.

Add missing break statment to case statement in Process::ShouldBroadcastEvent.

Add new command, "process handle" to allow users to control process behavior on
the receipt of various Unix signals (whether the process should stop; whether the
process should be passed the signal; whether the debugger user should be notified
that the signal came in).

247399230d Fixed C++ class clang type creation and display by making sure we omit
artifical members (like the vtable pointer member that shows up in the DWARF).
We were adding this to each class which was making all member variables be off
by a pointer size.

Added a test case so we can track this with "test/forward".

Fixed the type name index in DWARF to include all the types after finding
some types were being omitted due to the DW_AT_specification having the
DW_AT_declaration attribute which was being read into the real type instances
when there were forward declarations in the DWARF, causing the type to be
omitted. We now check to make sure any DW_AT_declaration values are only
respected when parsing types if the attribute is from the current DIE.

After fixing the missing types, we ran into some issues with the expression
parser finding duplicate entries for __va_list_tag since they are built in
types and would result in a "duplicate __va_list_tag definition" error. We
are now just ignoring this name during lookup, but we will need to see if
we can get the name lookup function to not get called in these cases.

Fixed an issue that would cause an assertion where DW_TAG_subroutine_types
that had no children, would not properly make a clang function type of:
"void (*) (void)".

e02b850483 Modified the "breakpoint set --name NAME" to be the auto breakpoint set
function. It will inspect NAME and do the following:
- if the name contains '(' or starts with "-[" or "+[" then a full name search
  will happen to match full function names with args (C++ demangled names) or
  full objective C method prototypes.
- if the name contains "::" and no '(', then it is assumed to be a qualified
  function name that is in a namespace or class. For "foo::bar::baz" we will
  search for any functions with the basename or method name of "baz", then
  filter the results to only those that contain "foo::bar::baz". This allows
  setting breakpoint on C++ functions and methods without having to fully
  qualify all of the types that would appear in C++ mangled names.
- if the name contains ":" (not "::"), then NAME is assumed to be an ObjC
  selector.
_ otherwise, we assume just a plain function basename.

Now that "--name" is our "auto" mode, I introduced the new "--basename" option
("breakpoint set --basename NAME") to allow for function names that aren't 
methods or selectors, just basenames. This can also be used to ignore C++
namespaces and class hierarchies for class methods.

Fixed clang enumeration promotion types to be correct.

450e3f3c77 Fixed the Objective C method prototypes to be correct (the selectors weren't
being chopped up correctly). The DWARF plug-in also keeps a map of the ObjC
class names to selectors for easy parsing of all class selectors when we parse
the class type.

46747022d2 Added the ability to get error strings back from failed
lldb_private::RegularExpression compiles and matches with:

    size_t
    RegularExpression::GetErrorAsCString (char *err_str, 
                                          size_t err_str_max_len) const;
    
Added the ability to search a variable list for variables whose names match
a regular expression:

    size_t
    VariableList::AppendVariablesIfUnique (const RegularExpression& regex, 
                                           VariableList &var_list, 
                                           size_t& total_matches);


Also added the ability to append a variable to a VariableList only if it is 
not already in the list:

    bool
    VariableList::AddVariableIfUnique (const lldb::VariableSP &var_sp);

Cleaned up the "frame variable" command:
- Removed the "-n NAME" option as this is the default way for the command to
  work.
- Enable uniqued regex searches on variable names by fixing the "--regex RE"
  command to work correctly. It will match all variables that match any
  regular expressions and only print each variable the first time it matches.
- Fixed the option type for the "--regex" command to by eArgTypeRegularExpression
  instead of eArgTypeCount

864174e100 Added a new test case to test signals with.
Added frame relative frame selection to "frame select". You can now select
frames relative to the current frame (which defaults to zero if the current
frame hasn't yet been set for a thread):

The gdb "up" command can be done as:
(lldb) frame select -r 1
The gdb "down" command can be done as:
(lldb) frame select -r -1

Place the following in your ~/.lldbinit file for "up" and "down":

command alias up frame select -r 1
command alias down frame select -r -1

Greg Clayton
6d7e77b9dc Added new options to memory read to allow saving memory to disk
as binary bytes or as an ASCII text dump. 
- The output file is specified with the  "--outfile FILE" option.
- The memory can be appended to an existing file using the "--append" option. 
- The memory will be written as an ASCII text dump by default, or as 
  binary with the "--binary" option. 

Added new options to memory write to allow writing all or part of
a file on disk to target memory:
- The input file is specified using the "--infile FILE" option
- The offset at which to start in the file defaults to zero, but
  can be overridden using the "--offset OFFSET" option. If the
  size is not specified, the remaining number of bytes in the file
  will be used as the default byte size.
- The number of bytes to write defaults to the entire file byte
  size, but can be changed with the "--size COUNT" option.

c6ed542c90 More SWIG cleanup. Moved the breakpoint callback function back to the

05faeb7135 Cleaned up the SWIG stuff so all includes happen as they should, no pulling
tricks to get types to resolve. I did this by correctly including the correct
files: stdint.h and all lldb-*.h files first before including the API files.
This allowed me to remove all of the hacks that were in the lldb.swig file
and it also allows all of the #defines in lldb-defines.h and enumerations
in lldb-enumerations.h to appear in the lldb.py module. This will make the
python script code a lot more readable.

Cleaned up the "process launch" command to not execute a "process continue"
command, it now just does what it should have with the internal API calls
instead of executing another command line command.

Made the lldb_private::Process set the state to launching and attaching if
WillLaunch/WillAttach return no error respectively.
