Handle terms (pids,ports and refs) from nodes with a 'creation' value larger than 3. This is a preparation of the distribution protocol to allow OTP 19 nodes to correctly communicate with future nodes (20 or higher). The 'creation' value differentiates different incarnations of the same node (name).

Do not accept Nan and Infinity values
Erlang does not accept these values, so we return an error in the C interface rather than letting them through to the Erlang VM, which rejects the message with a somewhat cryptic "bad external term".

Limited support for unicode atoms in the external format and in the internal representation of the vm. This is a preparative feature in order to support communication with future releases of Erlang/OTP that may create unicode atoms.

Teach lib/erl_interface/configure.in to look for pthreads support in libc (where it can be found on QNX)
A minor tweak such that this configure *fails* if you pass --enable-threads and no pthreads support can be found.

ei: integer overflow in string/atom encoding
ei_encode_atom() and ei_encode_string() use strlen() to get the length of the buffer. As strlen() returns an unsigned long long and both ei functions take a signed integer, the length fields may overflow.
Check so that the results of strlen can be held in a signed integer. (Thanks to Michael Santos)

Fix using sizeof() for array given as function argument
When using the sizeof() operator for an array given as function argument it returns the size of the pointer. In this case, the affected function hex(char digest[16], char buff[33]) will just print 4 or 8 byte instead of the full length of 16 bytes, on 32bit and 64bit systems respectively.

erl_call: remove get_hostent
get_hostent does not properly handle IPv4 addresses on little endian platforms and fails with hostnames beginning with a number. Remove get_hostent and use ei_gethostbyname directly since gethostbyname supports IPv4 addresses.

compact IEEE 754 double encoding in external binary format for ei
Implement the compact IEEE 754 double encoding in external binary format for ei. Encoding for ei now always produces the NEW_FLOAT_EXT format. Decoding and term printing handle both the old ERL_FLOAT_EXT encoding and the new NEW_FLOAT_EXT encoding.
Legacy erl_interface code also handles the new encoding, but still produces the ERL_FLOAT_EXT encoding by default.
Also enable the DFLAG_NEW_FLOATS distribution flag.
ei_get_type() will return ERL_FLOAT_EXT regardless if the external format is encoded with ERL_FLOAT_EXT or NEW_FLOAT_EXT for doubles.
Reduce the number of copies of the code for encoding and decoding doubles throughout ei and erl_interface by instead calling the ei encoding and decoding functions wherever possible.
Restore commented-out float tests in ei_decode_SUITE and ei_encode_SUITE in lib/erl_interface/test. Modify them to make them match the style of other tests in the same suites.
These changes are based on an ei float patch from Serge Aleynikov originally submitted against R12B-2 in July 2008 and reworked by Steve Vinoski May 2010.

ei_print_term interprets a list of integers with values from 0 to 255 as a string. If the original list contains the integer 0, this is considered terminator of the string. This is incorrect. The function has now been modified to not look for '\0' in a string, but always print all characters.
