[PATCH] make record_insn_max_num uinteger

[Michael Snyder <msnyder@vmware.com>]

Treating this as obvious.  This variable can't be negative, so use
an unsigned.  And use uinteger set command instead of zinteger, so
that it will report itself as "unlimited" when set to zero.

	* record.c (record_insn_max_num): Make unsigned.
	(_initialize_record): Use uinteger instead of zinteger for
	set command, so that it will report "unlimited" for zero.
