Implement EC2 map.

EC2 map allows to use AWS services as eclap maps.  For example,
one may use an EC2 tag to map resource names to resource IDs, etc.

* src/ec2map.c: New file.
* src/io.c: New file.
* src/Makefile.am (eclat_SOURCES): Add new files.
* src/eclat.c (dump,eclat_trace_fun)
(dumpxml,write_callback): Move to io.c
(main): Register ec2 map.
Use eclat_io framework.
* src/eclat.h (eclat_io): New struct.
(eclat_io_init, eclat_io_free)
(eclat_io_shutdown, eclat_io_finish): New functions.
(eclat_map_drv_ec2): New extern.
