Also transitively updates a few golang.org/x/ dependencies, and the grpc and protobuf
dependencies.
Right now, Boulder expects to be able to connect to syslog, and panics
if it's not available. We'd like to be able to log to stdout/stderr as a
replacement for syslog.
- Add a detailed timestamp (down to microseconds, same as we collect in
prod via syslog).
- Remove the escape codes for colorizing output.
- Report the severity level numerically rather than with a letter prefix.
Add locking for stdout/stderr and syslog logs. Neither the [syslog] package
nor the [os] package document concurrency-safety, and the Go rule is: if
it's not documented to be concurrent-safe, it's not. Notably the [log.Logger]
package is documented to be concurrent-safe, and a look at its implementation
shows it uses a Mutex internally.
Remove places that use the singleton `blog.Get()`, and instead pass through
a logger from main in all the places that need it.
