[PATCH v2] Add shortcuts for "nexti" and "stepi" commands in Single-Key mode


From: Ruslan Kabatsayev <b7.10110111@gmail.com>

Currently, "layout asm" is not so useful as "layout src" with Single-Key mode:
you have to use multi-key commands like "ni" and "si" to do single-stepping.
This patch adds, in addition to "next" and "step" commands, corresponding
assembly-level ones - "nexti" and "stepi" - to Single-Key mode, with the
shortcuts of "o" (from "step Over") and "i" (from "Step Into") respectively.

gdb/ChangeLog:

	* tui/tui.c: Add "nexti" and "stepi" to the tui_commands list
	* doc/gdb.texinfo: Document the new shortcuts in Single-Key mode
