/**
* GDB/MI thread list parsing.
*
* Example 1:
*
* -thread-info
* ^done,threads=[
* {id="2",target-id="Thread 0xb7c8ab90 (LWP 7010)",
* frame={level="0",addr="0x08048bba",func="my_func",args=[{name="arg",value="0xbff056f5"}],
* file="my_test.cc",fullname="/home/francois/GDB/my_test.cc",line="26"},
* state="stopped"},
* {id="1",target-id="Thread 0xb7c8b8d0 (LWP 7007)",
* frame={level="0",addr="0x08048a77",func="timer",args=[{name="duration",value="0xbff056f5 \"10\""}],
* file="my_test.cc",fullname="/home/francois/GDB/my_test.cc",line="39"},
* state="stopped"}
* ],current-thread-id="2"
*
*
* Example 2:
*
* -thread-info 2
* ^done,threads=[
* {id="2",target-id="Thread 0xb7c8ab90 (LWP 7010)",
* frame={level="0",addr="0x08048bba",func="my_func",args=[{name="arg",value="0xbff056f5"}],
* file="my_test.cc",fullname="/home/francois/GDB/my_test.cc",line="26"},
* state="stopped"}
* ]
*
*
* Example 3 (non-stop):
*
* -thread-info
* ^done,threads=[
* {id="2",target-id="Thread 0xb7d6d6b0 (LWP 14494)",state="running"},
* {id="1",target-id="Thread 0xb7c8b8d0 (LWP 7007)",
* frame={level="0",addr="0x08048a77",func="timer",args=[{name="duration",value="0xbff056f5 \"10\""}],
* file="my_test.cc",fullname="/home/francois/GDB/my_test.cc",line="39"},
* state="stopped"}
* ],current-thread-id="1"
*
*
* Example 4 (non-stop):
*
* -thread-info 1
* ^done,threads=[{id="1",target-id="Thread 0xb7d6d6b0 (LWP 14494)",state="running"}]
*
*
* Example 5 (Dicos):
*
* -thread-info 1
* ^done,threads=[
* {id="1",target-id="Thread 162.32942",details="JUnitProcess_PT (Ready) 175417582794 8572423",
* frame={level="0",addr="0x1559a318",func="mainExpressionTestApp",args=[],
* file="/local/home/lmckhou/TSP/TADE/example/JUnitProcess_OU/src/ExpressionTestApp.cc",
* fullname="/local/home/lmckhou/TSP/TADE/example/JUnitProcess_OU/src/ExpressionTestApp.cc",line="279"},
* state="stopped"}]
*
* With GDB 7.1, a new 'core' field is present to indicate which core the thread is on.
* The parsing of this new field is handled by {@link MIThread}
*
* -thread-info
* ^done,threads=[
* {id="1",target-id="process 1307",
* frame={level="0",addr="0x08048618",func="main",args=[],
* file="a.cc",fullname="/local/lmckhou/testing/a.cc",line="9"},
* state="stopped",
* core="2"}],
* current-thread-id="1"
