Add ec_dec_tell() to report the same information as ec_enc_tell() decode side. Remove ec_enc_tell() and replace it with ec_enc_tellf(): just request 0 fractional bits if you want an integer value.

Add ec_enc_tellf, which can return the number of bits used to fractional precision.

Add oc_enc_tell to report an estimate of the number of bits used so far.
...
Remove the special case for 0 in EC_ILOG, as we never pass it 0 and this
generates slightly better code.
Update ec_enc_bits64 to split the encoded values along word boundaries...
this should generate slightly better code, as well as fix a subtle bug (the
proper bits were not being masked out of the low part).
However, this will render previous streams that used this function undecodable
(to my knowledge, no one is actually using it yet).

Updated broken paper URLs.
Cleaned up non-multiply-free range coder documentation (e.g., stop claiming
it's multiply-free).
