2012-12-14erts: Reduce max heap sizesBjörn-Egil Dahlberg
Reduces max heap sizes to max addressable memory space. In reality this could be even less since we need at least twice as much adressable memory to do a garbage collection. The rest of the system also uses memory thus further constraining heap memory space and in the 64 bit case we really only have 48 bits mappable memory.

2012-12-14erts: Reintroduce mseg options amcbf and rmcbfBjörn-Egil Dahlberg
Used with new sbc cache
2012-12-14erts: Optimize erl_alloc_util.c by substitute MBC_BLK_SZSverker Eriksson
with either MBC_ABLK_SZ or MBC_FBLK_SZ in all cases when we already know what kind of block it is.
2012-12-14erts: Fix bug when allocating size near sbc_thresholdSverker Eriksson
A block larger than sbc_threshold can be allocated in MBC if the subsequent "residue block" is smaller than min_block_size. Solved by lowering sbc_threshold to ("hard limit" - min_block_size).
2012-12-14erts: Make gc sizes fit into MB Carrier blocksBjörn-Egil Dahlberg
* Account for block header size in gc-sizes * Also slow down growth to 20% instead of 25% when size threshold is reached

2012-11-30erts: Change default of erl_crash.dumpBjörn-Egil Dahlberg
* Create an erl_crash.dump if no heart exists and no ERL_CRASH_DUMP_SECONDS is set (behaviour changed) * Don't create an erl_crash.dump if heart do exists and no ERL_CRASH_DUMP_SECONDS is set (behaviour not changed) This changes the behaviour back to the R15B02 default considering if a beam was running with no heart. The motivation is that we want a fast heart to fast restart erlang if it crashes but to be able to get non-truncated erl_crash.dumps via setting ERL_CRASH_DUMP_SECONDS if we so desire.

2012-11-22Teach erts_bs_append not to dump corePatrik Nyblom
When erts_bs_append() calls the garbage collector, it has set the PB_ACTIVE_WRITER flag in the ProcBin for the binary object is about to be appended to. Therefore, it is expected that the garbage collector should neither move nor shrink the binary object. But if the garbage collector does a minor collection (thereby clearing the PB_ACTIVE_WRITER flag in the ProcBin) and there is still not enough heap space, there will be a second major garbage collection. During the major collection (since the the PB_ACTIVE_WRITER flag was cleared), the binary object may be shrunk or moved (depending on sizes and how many other writable binaries there are in the process). Avoid the problem by clearing the PB_ACTIVE_WRITER flags in a separate pass after the garbage collection(s). Thanks to Denis Titoruk for helping us find this bug.
