merge revision(s) 38202,38238,38324,38326: [Backport #7527]
* test/dl/test_func.rb (test_name_with_block, test_bind, test_qsort1):
call unbind to release the callback closure because maximum number
of callbacks is limited to DL::MAX_CALLBACK (== 5) with pure DL
without Fiddle.
* ext/dl/lib/dl/func.rb (DL::Function#unbind, #bound?): suppress
NoMethodError when Fiddle is available. [ruby-core:50756] [Bug #7543]
* test/dl/test_func.rb (test_bound*, test_unbind*): tests for the above.
* ext/dl/lib/dl/func.rb (DL::Function#initialize, DL::Function#bind):
ABI should be set by using CFunc#calltype even when Fiddle is used.
When Fiddle is used and a block is given, name shoud not be ignored.
[ruby-core:50562] [Bug #7514]
* ext/dl/lib/dl/import.rb (DL::Importer#bind_function): should respect
abi and name when Fiddle is used.
* test/dl/test_func.rb (test_name_with_block): test for "name" method
with giving a block.
