Reader.Reset: recover from errors.
...
When a Reader encounters an error, its internal state may be corrupted.
So Reset needs to be extra thorough, to avoid cascading errors.
Based on PR 37 by Sovianum.

Revert "Faster bit writing."
...
This reverts commit c3da72aa01
.
With the sample data from issue 22, one byte in the output file is zero
instead of the correct value. For now at least, we'll go back to the old
way of writing bits.

Use a 64-bit store in writeBits.
...
This is an optimization that was present in the C version (behind an
ifdef). It gives a nice speed boost to the lower compression levels.

Read multiple bytes in findMatchLengthWithLimit
...
Use 64- or 32-bit loads instead of reading a byte at a time. The
original C source did something like this, in a very C-ish way. It
needed to be simplified to translate it to Go. The exact way this works
was suggested by the assembly code in github.com/golang/snappy.

Reuse buffers and objects using sync.Pool
...
This reduces the amount of garbage generated and relieves pressure on
the GC.
For a workload without reusing the Writer (using Writer.Reset) the number of allocations goes from 31 to 9.
While for a workload when you reuse the Writer the number of allocations goes from 25 to 0.
