    Log Message:
    Fix lost 'unexpected characters' received in ANSI get cursor position response

    Unexpected characters received (maybe typed by the user) were supposed to
    be stuffed in the keyboard input buffer using ungetstr(), but the input string was cleared rather than NUL-terminated before logging the expected character and calling ungetstr(), so nothing (a blank string) was logged and nothing was stuffed in the keyboard input-buffer in this case. Just an off-by-one bug.

    This should fix issue #304. Thanks to Keyop and Nelgin for their persistence
    in reporting and testing (in #synchronet at irc.synchro.net).

    Log Message:
    Fix CID 319174 (Out-of-bounds write) correctly

    This Coverity reported issue was previously resolved (incorrectly) with
    commit 0c441424 which also introduced a bug that ate all the unexpected
    cursor position report characters (causing issue #304).

    The correct fix was to compare the response length against the buffer size minus one, to leave room for the NUL terminator.

    While fixing this and issue #304, I noticed that this function was using the response length ('rsp') as both the state machine state and string length, which didn't work right if a nearly-matching report/response was received:
    the x/y values would have been stripped from the response before stuffing
    in the keyboard input buffer. So a bit of a refactor here using a proper
    state machine variable.

    Remove the call to sync() from ansi_getlines()

    This was needed back in the v2 days to be sure the escape sequence was sent *after* an output buffer before might've been cleared by a user's abort/Ctrl-C action. SYNC/ASYNC called riosync() which called rioctl(TXSYNC) and we have no equivalent in Synchronet for TCP/IP (modern sbbs). A user's Ctrl-C will clear all pending I/O, but won't prevent subsequent output from being sent (until
    the abort condition is cleared) as used to be the case with serial I/O.
