Part of the project renaming, issue #981.
After this, users will need to mv their $GOPATH/src/camlistore.org to
$GOPATH/src/perkeep.org. Sorry.
This doesn't yet rename the tools like camlistored, camput, camget,
camtool, etc.
Also, this only moves the lru package to internal. More will move to
internal later.
Also, this doesn't yet remove the "/pkg/" directory. That'll likely
happen later.
This updates some docs, but not all.
devcam test now passes again, even with Go 1.10 (which requires vet
checks are clean too). So a bunch of vet tests are fixed in this CL
too, and a bunch of other broken tests are now fixed (introduced from
the past week of merging the CL backlog).

improving proxycache
- added fuller sample config to the package documentation
- switched the stats caching from sorted.kv to the stats blobserver
- added a cleaning mechanism to evict the least recently used blobs
- implemented StatBlobs to actually inspect the local cache. It still
always consults the origin, but only for the blobs necessary after
giving the cache a 50ms headstart.
- logging a few errors that were previously ignored
- added tests modeled after the tests for the localdisk blobstore
- added a method to verify the cache, and call it on initialization
- added a strictStats option to always get stats from the origin
- filling in cacheBytes on initialization
improving stats blobserver
- implemented a few more of the blobserver interfaces, Enumerator and
Remover
- Fixed a bug(?) in ReceiveBlob that seemed to prevent it from actually
storing stats
- added a test
minor improvements include:
- blobserver/memory: allowing the memory blobserver to hold actually
infinite items, if desired
- blobserver: closing dest in the NoImpl blobserver, as required by the
BlobEnumerator interface
- storagetest: not closing dest leads to deadlock
- lru: max entries of 0 now means infinite (maybe do anything <0?)
- test: a helper function to create a random blob using a global random
source that is, by default, deterministic, to make test results more
consistent.
In the future, an improved BlobHub or similar interface could allow a
tighter feedback loop in providing cache consistency. i.e. the cache
could register with backend stores to be notified of content updates,
minimizing the time between backend changes and cache correction.
The proxycache will verify itself at startup, reporting an error if
any of its blobs do not exist in the backend storage or if the backend
storage has a different size for the content than the cache.

Most of it replaced with vendor/go4.org/types and
vendor/go4.org/readerutil
u32 went where needed in pkg/blobserver/*
invertedBool went in pkg/types/serverconfig
atomics64 went in pkg/fs

This is round two of simplifying the BlobStreamer interface. The
continuation tokens are now sent per-item. This permits the following
item (NewMultiBlobStreamer) but also simplifies the return value (only
returns an error now) and permits the use of buffered channels as the
destination without getting out of sync.
The new NewMultiBlobStreamer is like io.MultiReader, but for
BlobStreamers, letting them be stitched together. This will be used by
the blobpacked storage layer to simplify its code, so it doesn't need
to deal with the handoff between loose and packed blobs itself. This
MultiBlobStreamer needs a 1 element buffer, which wasn't compatible
with the old BlobStreamer interface, hence the change to include the
continuation tokens with the blob on the channel.
Finally, add a new storagetest function for testing any blobstreamer
and use it for NewMultiBlobStreamer, diskpacked, and later in
blobpacked.
Updates #532

Not just in blob.SizedRef, but in blobserver.Fetch and
blobserver.FetchStreaming, too.
Blobs have a max size of 10-32 MB anyway, and the index.Corpus is now using
uint32 to save memory.

Regressed from rev cb6f423e. Eventually pkg storagetest should test all methods of blobserver.Storage
for all storage target types.

A lot is still broken, but most stuff at least compiles now.
The directory tree has been rearranged now too. Go libraries are now
under "pkg". Fully qualified, they are e.g. "camlistore.org/pkg/jsonsign".
The go tool cannot yet fetch from arbitrary domains, but discussion is
happening now on which mechanism to use to allow that.
For now, put the camlistore root under $GOPATH/src. Typically $GOPATH
is $HOME, so Camlistore should be at $HOME/src/camlistore.org.
Then you can:
$ go build ./server/camlistored
... etc
The build.pl script is currently disabled. It'll be resurrected at
some point, but with a very different role (helping create a fake
GOPATH and running the go build command, if things are installed at
the wrong place, and/or running fileembed generators).
Many things are certainly broken.
Many things are disabled. (MySQL, all indexing, etc).
Many things need to be moved into
camlistore.org/third_party/{code.google.com,github.com} and updated
from their r60 to Go 1 versions, where applicable.
The GoMySQL stuff should be updated to use database/sql and the ziutek
library implementing database/sql/driver.
Help wanted.
