Introduce ALPM_BUFFER_SIZE constant

This takes the place of three previously used constants:
ARCHIVE_DEFAULT_BYTES_PER_BLOCK, BUFFER_SIZE, and CPBUFSIZE.

In libarchive 3.0, the first constant will be no more, so we can ensure
we are forward-compatible by removing our usage of it now. The rest are
unified for consistency.

By default, we will use the value of BUFSIZ provided by <stdio.h>, which
is 8192 on Linux. If that is undefined, a default value is provided.
