Our test cases spew a lot of files and directories around $TMPDIR. Make more
thorough use of the testing package's TempDir methods to ensure these are
cleaned up.
In a few cases, this required plumbing test contexts through existing helper
code. In a couple places an explicit path was required, to work around cases
where we do global setup during a TestMain function. Those cases probably
deserve more thorough cleansing (preferably with fire), but for now I have just
worked around it to keep focused on the cleanup.
During file rotation and WAL shutdown, there was a race condition between users
of an autofile and its termination. To fix this, ensure operations on an
autofile are properly synchronized, and report errors when attempting to use an
autofile after it was closed.
Notably:
- Simplify the cancellation protocol between signal and Close.
- Exclude writers to an autofile during rotation.
- Add documentation about what is going on.
There is a lot more that could be improved here, but this addresses the more
obvious races that have been panicking unit tests.
## Description
Internalize some libs. This reduces the amount ot public API tendermint is supporting. The moved libraries are mainly ones that are used within Tendermint-core.
* libs/common: Refactor libs/common 5
- move mathematical functions and types out of `libs/common` to math pkg
- move net functions out of `libs/common` to net pkg
- move string functions out of `libs/common` to strings pkg
- move async functions out of `libs/common` to async pkg
- move bit functions out of `libs/common` to bits pkg
- move cmap functions out of `libs/common` to cmap pkg
- move os functions out of `libs/common` to os pkg

* add changelog entry
* fix goimport issues
* run gofmt
* Enforce file permissions in case they've changed
* test behaviour for autofile
* use testify in tests and rename `fInf` to `fileInfo`
* return an error if file permissions have changed
- if we can't read the file, we'll still panic
* get rid of "github.com/pkg/errors" dependency
* address review comments:
- prefix instead of suffix
- add state to err and construct formatting in Error() method
* address review comments:
- move error to libs/errors
