When building with docker, we don't have a _full_ git repo.

docs: add ship date and next release issue opening time

docker: libdl dependency

Adds estimated shipping date (can be fuzzy) to the release issue template and clarifies the time before which the next release issue should be opened. This communicates expectations for when the new release is due and will help with planning of included features. The community could even suggest inclusions.

docs: improvements to the release doc

plugins: add support for plugin configs

* Adds missing items to ToC
* Adds sub-level items to ToC (there's not many, lets allow people to more easily skip to a section)
* Moves release process illustration to the top of the release flow section - it's an overview, it should be at the start not the end
* Fix a typo
* Removes braces in "Goal(s):" where there is clearly more than one

For now, configs specified in `daemon --init-config` and `init CONFIG` are not
available. We should fix this eventually but isn't necessary for now (and
supporting this will be annoying).

Update README.md

Removed OpenBSD line per discussion started with https://github.com/ipfs/docs/issues/254#issuecomment-526372366

doc: remove gmake instructions

This should now "just work". Calling `make` on non-linux platforms will invoke
`gmake` automatically and we now disable fuse on *bsd platforms.

feat: add ability to use existing config during init

doc: expand and cleanup badger documentation

feat: improve plugin preload logic

version: don't print 'VERSION-' if no commit is specified

fixes #6022

dep: update bitswap

fixes a bunch of lock contention.

dep: update deps

Fixes some unsafe uses of the "unsafe" package.

fixes a long-standing race condition

* Swarm: fixes data race.
* Datastore: make delete idempotent.

Update go-libp2p, fix tests with weak RSA keys

"identity" is the official name

We can no longer test this with bad keys. Unfortunately, good keys will likely
contain a newline and we have no way to send such keys to the server due to how
API requests are formatted.

dep: update blockstore + bbloom
