[PATCH 3/3] use SIDEBAND_*_ERROR constants in pack protocol

[iheffner@gmail.com]

From: Ivan Heffner <iheffner@gmail.com>

Switched calls to send_sideband() for pack protocol errors to use
SIDEBAND_PROTOCOL_ERROR and SIDEBAND_REMOTE_ERROR in place of the
sideband magic numbers of -2 and -1, respectively.
