[eclipse-pmc] API request renaming of StatusAdapter#getHandlingHint()

[Tod Creasey <Tod_Creasey@xxxxxxxxxx>]

REQUEST 
Change of the following API 

int StatusAdapter#getHandlingHint() to be renamed to  int
StatusAdapter#getStyle() 
void StatusAdapter#setHandlingHint(int
handlingHint) to be renamed to StatusAdapter#setStyle(int style)

Addition of the following API
int StatusManager#BLOCK - block the
return from handleStatus until the user has responded
int StatusManager#NO_BLOCK - do not
block the return from handleStatus until the user has responded

GOALS/BENEFITS: 
The name of the handlingHint in the status handling facility should be
renamed to be consistent with Eclipse conventions such as SWT. This flag
is also stronger than a hint and so the name hint is misleading.

RISKS
No known risks as we are currently the only consumers .
