  Log Message:
  [profile] Add binary ids into indexed profiles

This patch adds support for including binary ids in an indexed profile.
It adds a new field into the header that points to the offset of the
binary id section. The binary id section consists of a size of the
section, and a list of binary ids (if they are present) that consist
of two parts: length and data.

This patch guarantees that indexed profile is backwards compatible
after adding binary ids.
