Johnny Chen f6eaba85a8 Add test_display_source_python() test case to TestSourceManager.py which uses
the lldb PyThon API SBSourceManager to display source files.

To accomodate this, the C++ SBSourceManager API has been changed to take an
lldb::SBStream as the destination for display of source lines.  Modify SBStream::ctor()
so that its opaque pointer is initialized with an StreamString instance.

parser.

Greg Clayton bbdabce2f7 Added symbol table access through the module for now. We might need to expose
a SBSymtab class, but for now, we expose the symbols through the module.

Greg Clayton f7d6a2a6a8 Added a less than operator that will compare the internal opaque pointer values so SBBroadcaster objects can be contained in ordered containers or sorted.

Greg Clayton d46c87a1a8 More reverting of the EOF stuff as the API was changed which we don't want to
do. Closing on EOF is an option that can be set on the 
lldb_private::Communication or the lldb::SBCommunication objects after they
are created. Of course the EOF support isn't hooked up, so they don't do 
anything at the moment, but they are left in so when the code is fixed, it 
will be easy to get working again.

Caroline Tice 82305fc59a Add proper EOF handling to Communication & Connection classes:
Add bool member to Communication class indicating whether the
Connection should be closed on receiving an EOF or not.  Update the
Connection read to return an EOF status when appropriate.  Modify the
Communication class to pass the EOF along or not, and to close the
Connection or not, as appropriate.

Jim Ingham f48169bb4f Moved the code in ClangUserExpression that set up & ran the thread plan with timeouts, and restarting with all threads into a utility function in Process. This required a bunch of renaming.
Added a ThreadPlanCallUserExpression that differs from ThreadPlanCallFunction in that it holds onto a shared pointer to its ClangUserExpression so that can't go away before the thread plan is done using it.

Fixed the stop message when you hit a breakpoint while running a user expression so it is more obvious what has happened.

Johnny Chen beae523a20 Fill in more test sequences for Python API SBFrame.LookupVarInScope(name, scope).
Change SBFrame::LookupVarInScope() to also work with "global" scope in addition
to "local" and "parameter" scope.

Greg Clayton 4e78f60660 Added the ability to get more information on the SBThread's stop reason
by being able to get the data count and data. Each thread stop reason
has one or more data words that can help describe the stop. To do this
I added:

    size_t
	SBThread::GetStopReasonDataCount();

	uint64_t
	SBThread::GetStopReasonDataAtIndex(uint32_t idx);

Greg Clayton 7481c20f09 Fixed FileSpec's operator == to deal with equivalent paths such as "/tmp/a.c"
and "/private/tmp/a.c". This was done by adding a "mutable bool m_is_resolved;"
member to FileSpec and then modifying the equal operator to check if the
filenames are equal, and if they are, then check the directories. If they are
not equal, then both paths are checked to see if they have been resolved. If
they have been resolved, we resolve the paths in temporary FileSpec objects
and set each of the m_is_resolved bools to try (for lhs and rhs) if the paths
match what is contained in the path. This allows us to do more intelligent
compares without having to resolve all paths found in the debug info (which
can quickly get costly if the files are on remote NFS mounts).

Greg Clayton 2d4edfbc6a Modified all logging calls to hand out shared pointers to make sure we
don't crash if we disable logging when some code already has a copy of the
logger. Prior to this fix, logs were handed out as pointers and if they were
held onto while a log got disabled, then it could cause a crash. Now all logs
are handed out as shared pointers so this problem shouldn't happen anymore.
We are also using our new shared pointers that put the shared pointer count
and the object into the same allocation for a tad better performance.

Greg Clayton efabb123af Added copy constructors and assignment operators to all lldb::SB* classes
so we don't end up with weak exports with some compilers.

Jim Ingham 399f1cafa6 Added the equivalent of gdb's "unwind-on-signal" to the expression command, and a parameter to control it in ClangUserExpression, and on down to ClangFunction.

Greg Clayton 8f343b09e9 Added support for loading and unloading shared libraries. This was done by
adding support into lldb_private::Process:

    virtual uint32_t
    lldb_private::Process::LoadImage (const FileSpec &image_spec, 
                                      Error &error);

    virtual Error
    lldb_private::Process::UnloadImage (uint32_t image_token);

There is a default implementation that should work for both linux and MacOSX.
This ability has also been exported through the SBProcess API:

    uint32_t
    lldb::SBProcess::LoadImage (lldb::SBFileSpec &image_spec, 
                                lldb::SBError &error);

    lldb::SBError
    lldb::SBProcess::UnloadImage (uint32_t image_token);

Modified the DynamicLoader plug-in interface to require it to be able to 
tell us if it is currently possible to load/unload a shared library:

    virtual lldb_private::Error
    DynamicLoader::CanLoadImage () = 0;

This way the dynamic loader plug-ins are allows to veto whether we can 
currently load a shared library since the dynamic loader might know if it is
currenlty loading/unloading shared libraries. It might also know about the
current host system and know where to check to make sure runtime or malloc
locks are currently being held.

Modified the expression parser to have ClangUserExpression::Evaluate() be
the one that causes the dynamic checkers to be loaded instead of other code
that shouldn't have to worry about it.

Greg Clayton cfd1aced7e Cleaned up the API logging a lot more to reduce redundant information and
keep the file size a bit smaller.

Exposed SBValue::GetExpressionPath() so SBValue users can get an expression
path for their values.

Caroline Tice 20ad3c40f4 Add the ability to disable individual log categories, rather
than just the entire log channel.

Add checks, where appropriate, to make sure a log channel/category has 
not been disabled before attempting to write to it.

Greg Clayton 93aa84e83b Modified the lldb_private::TypeList to use a std::multimap for quicker lookup
by type ID (the most common type of type lookup).

Changed the API logging a bit to always show the objects in the OBJECT(POINTER)
format so it will be easy to locate all instances of an object or references
to it when looking at logs.

Sean Callanan 322f529b37 Added a user-settable variable, 'target.expr-prefix',
which holds the name of a file whose contents are
prefixed to each expression.  For example, if the file
~/lldb.prefix.header contains:

typedef unsigned short my_type;

then you can do this:

(lldb) settings set target.expr-prefix '~/lldb.prefix.header'
(lldb) expr sizeof(my_type)
(unsigned long) $0 = 2

When the variable is changed, the corresponding file
is loaded and its contents are fetched into a string
that is stored along with the target.  This string
is then passed to each expression and inserted into
it during parsing, like this:

typedef unsigned short my_type;
                             
void                           
$__lldb_expr(void *$__lldb_arg)          
{                              
    sizeof(my_type);                        
}
