erts: Add age order first fit allocator strategies

2018-02-12T12:23:15+00:00

ageffcaoff: Age First Fit Carrier, Address Order First Fit (within carrier)
ageffcbf  : Age First Fit Carrier, Best Fit (within carrier)
ageffcaobf: Age First Fit Carrier, Address Order Best Fit (within carrier)

Prefer old carriers, the older the better.

Reduce memory use of system_information:to_file/1

2018-01-11T09:39:57+00:00

The previous implementation generated a term, converted it to plain
text with io_lib:format/2, and then converted that to a binary
before writing it to disk.

We now emit the term as we go, which should make it a bit safer to
extract this information under load.
