[svn-r3602] 
Purpose: Usability enhancement

Description:
	- Added more information about the failure to all the throw's,
	i.e, member function name and more detail about the failure, where
	appropriate.  Also, added exception throws for private functions,
	such as p_close to provide more specific details.

	- Added two api functions: Exception::getFuncName() and
	Exception::getCFuncName() to provide the name of the member
	function where failure occurs.

	- Fixed some typos, one of which caused segn. fault in some
	situations (resetIdComponent was accidentally called twice
	in a couple of places :)

Platforms:
	arabica (sparc-sun-solaris 2.7)
