Dan McGee 7a873a8f12 Give libalpm native support for both libdownload and libfetch
This should remove the need for any additional patching to run on platforms
that have libfetch available but not libdownload. It isn't the prettiest,
but we have kept our libdownload impact down to just a few files, so it can
be easily done.

# UPDATING VERSION NUMBERS FOR RELEASES
#
# libalpm:
# current
# The most recent interface number that this library implements.
# revision
# The implementation number of the current interface.
# age
# The difference between the newest and oldest interfaces that this library
# implements. In other words, the library implements all the interface
# numbers in the range from number current - age to current.
#
# 1. Start with version information of `0:0:0' for each libtool library.
# 2. Update the version information only immediately before a public release of
# your software. More frequent updates are unnecessary, and only guarantee
# that the current interface number gets larger faster.
# 3. If the library source code has changed at all since the last update, then
# increment revision (`c:r:a' becomes `c:r+1:a').
# 4. If any interfaces have been added, removed, or changed since the last
# update, increment current, and set revision to 0.
# 5. If any interfaces have been added since the last public release, then
# increment age.
# 6. If any interfaces have been removed since the last public release, then
# set age to 0.
