Modularize the Adler32 checksum in checksums/adler32

Add a new option --disable-modules which allows for disabling any
set of modules that normally would be autoloaded.

Rename the Botan feature test macros from BOTAN_EXT_BLAH to BOTAN_HAS_BLAH,
which will be much more sensible especially when everything is done in this
fashion (eg, BOTAN_HAS_BLOWFISH or BOTAN_HAS_RSA, etc)
