SBProcess.GetSTDERR() not getting stderr of the launched process

Since we are launch the inferior with:

    process = target.LaunchSimple(None, None, os.getcwd())

i.e., without specifying stdin/out/err.  A pseudo terminal is used for
handling the process I/O, and we are satisfied once the expected output
appears in process.GetSTDOUT().

Johnny Chen 7cc3d31e15 Simplify the setup leading to the testing of ReadMemory(), ReadCStringFromMemory(), and ReadUnsignedFromMemory().
Instead of getting the location of the variable and converting the hex string to an int, just use
val.AddressOf().GetValueAsUnsigned() to compute the address of the memory region to read from.

Johnny Chen e7e8af807a Add a test sequence of SBProcess.ReadCStringFromMemory() with (char *)my_char_ptr as the address to read from.
char *my_char_ptr = (char *)"Does it work?";

Johnny Chen 49cb85db64 SBProcess.PutSTDIN() needs to be properly typemapped when swigging,
so that we can do Python scripting like this:

        target = self.dbg.CreateTarget(self.exe)

        self.dbg.SetAsync(True)
        process = target.LaunchSimple(None, None, os.getcwd())

        process.PutSTDIN("Line 1 Entered.\n")
        process.PutSTDIN("Line 2 Entered.\n")
        process.PutSTDIN("Line 3 Entered.\n")

Add TestProcessIO.py to exercise the process IO API: PutSTDIN()/GetSTDOUT()/GetSTDERR().

Greg Clayton fe42ac4d0a Cleaned up the SBType.h file to not include internal headers and reorganized
the SBType implementation classes.

Fixed LLDB core and the test suite to not use deprecated SBValue APIs.

Added a few new APIs to SBValue:

    int64_t
    SBValue::GetValueAsSigned(int64_t fail_value=0);

    uint64_t
    SBValue::GetValueAsUnsigned(uint64_t fail_value=0)

Johnny Chen 1d3e880c2c Passing in os.ctermid() as the arg for SBTarget.Launch(...) for stdin_path, stdout_path, and stderr_path
is just wrong and resulted in the inferior's output getting mixed into the GDB remote communication's
log file.  Change all test cases to not pass os.ctermid() and either use SBTarget.LaunchSimple() or
SBTarget.Launch() and pass None as stdin_path/stdout_path/srderr_path to use a pseudo terminal.

Johnny Chen 9a07aba962 The lldbtest.TestBase.DebugSBValue(self, val) method call now does not need the frame argument.
Only the val (of SBValue type) argument is needed.

Johnny Chen 5a0bee7c5f The extra burden for the Python API test case to assign its process object to self.process
in order to have its process cleaned up (terminated) upon tearDown is gone for good.
Let's simplify a bunch of Python API test cases.

Johnny Chen 4ebd019b97 Now that we have added a post-processing step for adding truth value testing to
those lldb objects which implement the IsValid() method, let's change the rest of
the test suite to use the more compact truth value testing pattern (the Python way).

Jim Ingham 78a685aa2d Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the
expressions that are simple enough to get passed to the "frame var" underpinnings.  The parser code will
have to be changed to also query for the dynamic types & offsets as it is looking up variables.

The behavior of "frame var" is controlled in two ways.  You can pass "-d {true/false} to the frame var
command to get the dynamic or static value of the variables you are printing.

There's also a general setting:

target.prefer-dynamic-value (boolean) = 'true'

which is consulted if you call "frame var" without supplying a value for the -d option.

Johnny Chen 930e3ad51e Add a test case ProcessAPITestCase.test_remote_launch() which tests SBProcess.RemoteLaunch()
API with a process not in eStateConnected, and checks that the remote launch failed.

Modify SBProcess::RemoteLaunch()/RemoteAttachToProcessWithID()'s log statements to fix a
crasher when logging is turned on.

Johnny Chen d61816b5b8 Add TestTargetAPI.py:
// When stopped on breakppint 1, and then 2, we can get the line entries using
// SBFrame API SBFrame.GetLineEntry().  We'll get the start addresses for the
// two line entries; with the start address (of SBAddress type), we can then
// resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress().
//
// The two symbol context should point to the same symbol, i.e., 'a' function.


Add two utility functions to lldbutil.py:

o get_stopped_threads(process, reason):

  return the list of threads with the specified stop reason or an empty list if not found

o get_stopped_thread(process, reason):

  return the first thread with the given stop reason or None if not found

Johnny Chen 43766d6f12 Add two utility functions to lldbutil.py:
o int_to_bytearray()
o bytearray_to_int()

They return/interpret the bytearray in the little endian format.
For big endian, simply perform ba.reverse() on the bytearray object.

And modify TestProcessAPI.py to take advantage of the functions.

Johnny Chen cf386e24ab Add an API SBProcess::GetByteOrder() and add test cases which utilizes GetByteOrder(),
among other SBProcess APIs, to write (int)256 into a memory location of a global variable
(int)my_int and reads/checks the variable afterwards.

Johnny Chen 37f99fdb73 Add TestProcessAPI.py which exercises some Python SBProcess API. In particular, this tests
the SBProcess.ReadMemory() API, which, due to SWIG typemap'ing, expects 3 arguments (the location
to read from, the size in bytes to read, and an SBError object), and returns the result as a
Python string object.

On SnowLeopard where this has been tested, the SWIG script needs to be pampered (use the exact
same parameter names as in SBProcess.h) in order for this to work.
