-- Split input plugin checks out of configure.ac into m4/input.m4
-- Move m4/vcd.m4 (previously split out from configure.ac) into m4/input.m4
-- Fold m4/dl.m4 into configure.ac
-- Various miscellaneous cleanups throughout configure.ac and m4/*.m4

Some tests were rearranged (AC_TRY_LINK moved out of AC_TRY_RUN
cross-compilation case, with arrangements to maintain the semantics) to
avoid autoupdate errors.
Factored out common (duplicate) code in aa.m4.
Tested with autoconf 2.61; needs testing with 2.60.
