Made them powers of 2 for faster calculations.
500 encoded terms per reductions seemed a bit much, lowered to 32.
TERM_TO_BINARY_SIZE_FACTOR was not used in practice as it was only
applied to small binaries.
Lowered from 500kb to 256kb compressed bytes per trap call.

or if "too much" offheap binaries has been built

after it has built off_heap data
and then done at least one trap call.
The undo mechanism in dec_term does not work
if we build the magic binary after any other off_heap data.

<<131, 77, Len:32, Bits:8, Data/binary>>
badarg if Bits > 8
Used to return internally inconsistent bitstring
badarg if Len==0 and Bits > 0
Used to return invalid *huge* binary (size = (Uint)-1)
badarg if Bits==0 and Len > 0
Used to return valid binary as if Bits was 8

This complements 933e701 (OTP-10209).
Simple error example:
1> <<131,70,63,240,0,0,0,0,0,0>> = term_to_binary(1.0, [{minor_version,1}]).
** exception error: no match of right hand side value <<131,70,0,0,0,0,63,240,0,0>>
2> 1.0 = binary_to_term(<<131,70,63,240,0,0,0,0,0,0>>).
** exception error: no match of right hand side value 5.299808824e-315
But roundtrip always works:
3> 1.0 = binary_to_term(term_to_binary(1.0, [{minor_version,1}])).
1.0

Rewrite and extend of Happi's initial work
Extra_root to process structure to enable GC of state - Changed the
process structure to point to a separate struct, the struct also
contains a destructor function to allow for proper cleanup.
Rewrote encode_size_struct and enc_term to have internal versions with
reduction counters which will result in interrupt for later restart
when the counter reaches zero - removed the EWA_STACK from Happis
version and directly save the ESTACK's and WSTACK's in the above
mentioned struct (or array thereof) that are pointed out from the
process structure. The destructor will take care of the deallocation
in case of process death.
Added ESTACK and WSTACK macros to save and restore stack and to change
allocator, which makes the previously mentioned stack-save work.
Rewrote enc_term to not store pointers on the stack, and use one WSTACK
for commands etc and another ESTACK for Eterms - Slightly different than
Happis version to make halfword code simpler.
Rewrote encode_size_struct2 so that it does not store pointers on the
stack, also switched to ESTACK instead of WSTACK, this also handles
halfword correctly.
Added interfaces for chunkwise compression, that are
used from term_to_binary/2 when the compressed option is given.

The hybrid heap emulator was last working in the non-SMP R11B
run-time system. When the constant pools were introduced in R12B,
the hybrid heap emulator was not updated to handle them.
At this point, the harm from reduced readability of the code is
greater than any potential usefulness of keeping the code.

Still blocking code loading
|
|
|
|
Can still not setup -a, but cerl works.
|
|
Since refc binaries are now supported in literal pools, there is no
longer any need to allow the creation of over-sized heap binaries.
|
|
As a preparation for changing the calling convention for
BIFs, make sure that all BIFs use the macros. Also, eliminate
all calls from one BIF to another, since that also breaks
the calling convention abstraction.
|
|
This BIF's second parameter is a list of options.
Currently the only allowed option is {minor_version, Version}
where version is either 0 (default) or 1.
