Ravitheja Addepally d5d8d91c1d Initial implementation of SB APIs for Tracing support.
Summary:
This patch introduces new SB APIs for tracing support
inside LLDB. The idea is to gather trace data from
LLDB and provide it through this APIs to external
tools integrating with LLDB. These tools will be
responsible for interpreting and presenting the
trace data to their users.

The patch implements the following new SB APIs ->
-> StartTrace - starts tracing with given parameters
-> StopTrace - stops tracing.
-> GetTraceData - read the trace data .
-> GetMetaData - read the meta data assosciated with the trace.
-> GetTraceConfig - read the trace configuration

Tracing is associated with a user_id that is returned
by the StartTrace API and this id needs to be used
for accessing the trace data and also Stopping
the trace. The user_id itself may map to tracing
the complete process or just an individual thread.
The APIs require an additional thread parameter
when the user of these APIs wishes to perform
thread specific manipulations on the tracing instances.
The patch also includes the corresponding
python wrappers for the C++ based APIs.

"The lldb module contains the public APIs for Python binding.
Some of the important classes are described here:
o SBTarget: Represents the target program running under the debugger.
o SBProcess: Represents the process associated with the target program.
o SBThread: Represents a thread of execution. SBProcess contains SBThread(s).
o SBFrame: Represents one of the stack frames associated with a thread. SBThread
contains SBFrame(s).
o SBSymbolContext: A container that stores various debugger related info.
o SBValue: Represents the value of a variable, a register, or an expression.
o SBModule: Represents an executable image and its associated object and symbol
files. SBTarget contains SBModule(s).
o SBBreakpoint: Represents a logical breakpoint and its associated settings.
SBTarget contains SBBreakpoint(s).
o SBSymbol: Represents the symbol possibly associated with a stack frame.
o SBCompileUnit: Represents a compilation unit, or compiled source file.
o SBFunction: Represents a generic function, which can be inlined or not.
o SBBlock: Represents a lexical block. SBFunction contains SBBlock(s).
o SBLineEntry: Specifies an association with a contiguous range of instructions
and a source file location. SBCompileUnit contains SBLineEntry(s)."
