greatroar c9557b2822 internal/repository: Fix LoadBlob + fuzz test
When given a buf that is big enough for a compressed blob but not its
decompressed contents, the copy at the end of LoadBlob would skip the
last part of the contents.

Fixes #3783.

greatroar b7c990871f cmd/restic: Remove trailing "..." from progress messages
These were added after message since the last refactor of the progress
printing code. Also skips an allocation in the common case.

greatroar 0db1d11b2e archiver: Remove cleanup goroutine from BufferPool
This isn't doing anything. Channels should get cleaned up by the GC when
the last reference to them disappears, just like all other data
structures. Also inlined BufferPool.Put in Buffer.Release, its only
caller.

greatroar 5141228e0c repository: Re-tune indexmap allocation strategy
fd05037e1a changed the allocation batch
size from 256 to 128 under the assumption that an indexEntry is 60 bytes
on amd64, but it's 64: structs are padded out to a multiple of 8 for
alignment reasons. That means we'd waste no space in malloc even without
the batch allocation, at least on 64-bit machines. While that strategy
cuts the overallocation down dramatically for many small indexes, it also
seems to slow allocation down (Go 1.18, Linux, amd64, -benchtime=2s):

Instead, this patch sets a batch size of 4, which means no space is
wasted by malloc on 64-bit and very little on 32-bit. It still gets very
close to the savings from not allocating in batches, without requiring
special code for bits.UintSize==64. Benchmark results, again for
Linux/amd64:

The allocation method indexmap.newEntry has also been rewritten in a
form that is a few instructions shorter.

greatroar 2e0f1f5113 repository: Remove RunWorkers, report ctx.Err()
This removes RunWorkers, which had become mere overhead by successive
refactors. It also ensures that each former user of that function
returns any context error that occurs, so failure to complete an
operation is always reported as an error.

Apparently it can take a moment between closing a tempfile marked as
