(gdb-ready): Move declaration from gud.el to here.

(gdb-early-user-input): New variable.
(gdb): Reset gdb-flush-pending-output to nil and set
comint-input-sender here (before gdb-prompt), instead of...
(gdb-init-1): ...here.
(gdb-send): If Emacs is not ready, defer user input to...
(gdb-prompt): ...here.
