common: Delete unused functions (#2452)
These functions were not used anywhere within tendermint, or the cosmos-sdk. (The functionality is already duplicated in the cosmos-sdk types package) * common: Delete unused functions within byteslice * remove more unused code from strings.go and int.go * Remove more unused code from int.go * Fix testcase
