d2b09d854f *: use new errors handling library
Implement a new error handling library based on pkg/errors. It provides
stack saving on wrapping and exports some function to add stack saving
also to external errors.
It also implements custom zerolog error formatting without adding too
much verbosity by just printing the chain error file:line without a full
stack trace of every error.

* Add a --detailed-errors options to print error with they full chain
* Wrap all error returns. Use errors.WithStack to wrap without adding a
  new messsage and error.Wrap[f] to add a message.
* Add golangci-lint wrapcheck to check that external packages errors are
  wrapped. This won't check that internal packages error are wrapped.
  But we want also to ensure this case so we'll have to find something
  else to check also these.

b8c2b4020a db: use context functions
Use the go sql context functions (ExecContext, QueryContext etc...)

The context is saved inside Tx so the library users should only pass it one time
to the db.Do function.

3297244d5d db: retry on sqlite locked error
Since we are using the shared cache with the lock notify we won't receive
SQLITE_BUSY errors but we could receive SQLITE_LOCKED errors due to deadlocks or
locked tables on concurrent read and write transactions.

This patch catches this kind of errors and retries the tx until maxTxRetries.

9b2ce717c7 *: migrate to "golang.org/x/xerrors"
Just a raw replace of "github.com/pkg/errors".

Next steps will improve errors (like remote errors, api errors, not exist errors
etc...) to leverage its functionalities
