btif: Apply clang-format

clang-format doesn't understand block quotes of this form:

/*  This is not handled well
**  because there are two asterisks
**/

cd btif/

 # Replace '**' at the beginning of the line with ' *'

sed 's/^[*][*]/ \*/' -i include/* src/* test/* co/*
clang-format --style=file -i src/* include/* test/* co/*

Test: mma -j32
