- Added desc.c to handle file descriptors (avoid dupped, register handlers, ..) - Fix some bugs and optimize io paths - Added resolution methods - Maps are incomplete but better interfaced. Needs more work - Added io/t/map.c test program (not yet working) * Some fixups in many vapi files - Fix broken ones (syntax parsing error) - Complete them a bit more * Initial working version of a demo of list.h vala interface - Implemented as a Generic class - Designed as an Iterator, so 'foreach' can be used to iterate - Added example program iterating from vala and generating a list in C
