[PATCH v2 1/3] builtin/repack.c: change xwrite to write_in_full and report errors.

From: "Randall S. Becker" <rsbecker@nexbridge.com>

This change is required because some platforms do not support file writes of arbitrary sizes (e.g, NonStop). xwrite ends up truncating the output to the maximum single I/O size possible for the destination device. The result of write_in_full() is also passed to the caller, which was previously ignored.
