[python] Documentation fixes for gdb.Frame.

[Thiago Jung Bauermann <bauerman at br dot ibm dot com>]

Hi,

Just committed this.

gdb/
	* python/python-frame.c (gdbpy_initialize_frames): Mark comment as a
	note instead of a FIXME.

gdb/doc/
	* gdb.texinfo (Basic Python): Document `gdb.solib_address'.
	(Frames In Python): Document `Frame.unwind_stop_reason' and
	`Frame.block'.  Reword documentation for `Frame.read_var_value'.
