When we assign a value to err, make sure to also check for it being nil
afterwards. If those were intentionally unchecked, we should remove the
assignment in the first place. Those checks certainly never harm, but please
review thoroughly and let me know.

Two problems are fixed:
- Buffers are not returned to the pool in the case of errors.
- Per https://golang.org/pkg/bytes/#Buffer.Bytes, the slice returned
from bytes.Buffer.Bytes() is only valid until the next modification
of the buffer, so it must be copied before the buffer is returned to the pool.
Running `go test -race` detected the following:

The MaxOpenDescriptors option provides a middle ground solution between keeping
all packfiles open (as offered by the KeepDescriptors option) and keeping none
open.

Previously the error message when the connection was closed while
fetching was "object not found" and was misleading. Now when the
packfile size is 0 the error "unable to fetch packfile" is returned.

After clone only resolved deltas were added to the cache. This caused
slowdowns in small repositories where most objects can be held in cache.
It also makes packfiles reuse delta cache from the store. Previously it
created a new delta cache each time a packfile object was created. This
also slowed down a bit accessing objects and had an impact on memory
consumption when bases are added to the cache.

In the latest change the order was changed from offset order in
packfiles to hash order. This makes reading all the objects not as
efficient as before. It also created problems when the previous order
was expected.
Also added EntriesByOffset to indexes.

It uses less memory and is faster as slices don't have to be converted
from/to MemoryObject and they are indexed by offset.
