Fix a few bugs in ion_system_heap: Initialize the list node in the info block. Don't store size_remaining in a signed long, allocating >2GB could overflow, resulting in a call to sg_alloc_table with nents=0 which panics. alloc_largest_available will never return a block larger than size_remanining, so it can never go negative. Limit a single allocation to half of all memory. Prevents a large allocation from taking down the whole system.
