Subject: scripts/gdb: improve types abstraction for gdb python scripts
Change the read_u16 function so it accepts both 'str' and 'byte'
as type for the arguments.
When calling read_memory() from gdb API, depending on if
it was built with 2.7 or 3.X, the format used to return the
data will differ ( 'str' for 2.7, and 'byte' for 3.X ).
Add a function read_memoryview() to be able to get a
'memoryview' object back from read_memory() both with
python 2.7 and 3.X .
Tested with python 3.4 and 2.7
Tested with gdb 7.7
