This change removes the internal pad function in favor a more opimized paddedAppend function. Unlike pad, which would always alloate a new slice of the desired size and copy the bytes into it, paddedAppend only appends the leading padding when necesary, and uses the builtin append to copy the remaining source bytes. pad was also used in combination with another call to the builtin copy func to copy into a zeroed byte slice. As the slice is now created using make with an initial length of zero, this copy can also be removed. As confirmed by poking the bytes with the unsafe package, gc does not zero array elements between the len and cap when allocating slices with make(). In combination with the paddedAppend func, this results in only a single copy of each byte, with no unnecssary zeroing, when creating the serialized pubkeys. This has not been tested with other Go compilers (namely, gccgo and llgo), but the new behavior is still functionally correct regardless of compiler optimizations. The TestPad function has been removed as the pad func it tested has likewise been removed. ok @davecgh
