Subject: [PATCH] Optimize writeVarString.

Before:

BenchmarkWriteVarStr4    1000000              1114 ns/op
BenchmarkWriteVarStr10   1000000              1352 ns/op

After:

BenchmarkWriteVarStr4    5000000               291 ns/op
BenchmarkWriteVarStr10  10000000               248 ns/op

This is part ef the ongoing effort to optimize serialization as noted in
conformal/btcd#27.
