Provide a more detailed exception string

What steps will reproduce the problem?  
Run some script and make it raise NoSuchProcess or AccessDenied exception.
Example:

proc = subprocess.Popen('input', shell=1)
p = psutil.Process(proc.pid)
p.name
proc.kill()
proc.wait()
print p.get_children() 

What is the expected output?  


What do you see instead?  
The exception string will look like: 

"psutil.error.NoSuchProcess: process no longer exists" 

This message is pretty anonymous and doesn't give any information 
about the process which caused the exception.
This is particularly painful if the error suddenly occurs when 
running a program which iterates over multiple processes.
When this happens it would be helpful for debugging to know *what* 
process caused the exception, by providing at least its PID and, if available, its name.
Possible variants:

"psutil.error.NoSuchProcess: process no longer exists (pid=100)"
"psutil.error.NoSuchProcess: process no longer exists (pid=100, name='python')"
"psutil.error.AccessDenied: (pid=100)"
"psutil.error.AccessDenied: (pid=100, name='python')"

This is now implemented in r653 in which I also added a "name" 
attribute/parameter to exception classes.

Status: Fixed
