2010-06-07compact IEEE 754 double encoding in external binary format for eiSteve Vinoski
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. 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.

Debug trace output for connection activity could be enabled setting the trace level as an integer to the EI_TRACELEVEL environment variable. This option could also be read and set from a running program using ei_get_tracelevel(void) and ei_set_tracelevel(int).
