I'll change the result to size_t per Jan's request.
I'm kinda worried about putting people to extra effort when they
compile with -Wconversion which is why I went with int (thinking
people would rather just use an int).  But ok.

long long (+ unsigned long long) is ok by me.
I could also rename the functions to read_uleb128_to_ull (unsigned
long long) to allow for a day if/when someone wants
read_uleb128_to_uint64.  Ok?
