[Patch] PR Python/12692 Add gdb.selected_inferior() to Python interface.

[Kevin Pouget]

Hello,


I would like to introduce a new Python function,
`gdb.selected_inferior()', which returns the Python obj corresponding
to current_inferior; let me know what you think about it.
I named the function `selected_inferior' according to the existing
`selected_thread'.

Cordially,

Kevin

Space before open paren.

This is ok with this changed, pending doc review.
