The internal implementations for md5 and sha256 checksums have not been merged
from upstream sources for a long time. Instead of us carrying copies of code
from other projects, we should just support building against multiple libraries
that provide such functionality.
This patch removes the md5 and sha2 code (originally obtained from PolarSSL)
from our repository. The configure script will now error unless at least one
library supporting checksum generation is present, with the only library
currently supported being openssl. It will be relatively simple for other
such libraries (e.g. nettle) to be supported if anyone wishes to add them.

A look at what this does on 64 bit systems since we were using the
unnecessarily large 'unsigned long' type before even though it was 64
bits wide:
$ ~/bin/bloat-o-meter libalpm.so.old lib/libalpm/.libs/libalpm.so
add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-10412 (-10412)
function old new delta
md5_finish 370 356 -14
sha2_finish 547 531 -16
md5_process 3762 2643 -1119
sha2_process 20356 11093 -9263
The code size is nearly halved in the sha2 case (44% smaller code size),
and md5 gets a nice size reduction (27% smaller) as well.
We also move base64 code to <stdint.h> types as well; we can use
'uint32_t' rather than 'unsigned long' for at least two variables in the
decode function. This doesn't net the same size benefit as the hash code
case, but it is more proper.
