all: realign some structs to minimize memory usage

* Request: from 128 to 96 bytes (-32 bytes)
* Session: from 176 to 160 bytes (-16 bytes)
* Statement: from 56 to 48 bytes (-8 bytes)
* session_test.go:24:13: struct with 48 pointer bytes could be 40
* statement_test.go:13:13: struct with 32 pointer bytes could be 16
