The opam-0install-solver library unconditionally prints warnings, errors, notes

[gridbugs]

The library uses OpamConsole.warning and friends to print log messages. The problem with this is these functions print unconditionally; there is no way to set a log level and have, say, notes or warnings be suppressed. This makes it tricky to use this library in applications that want precise control over their output, like tui apps.

To fix this the library could use OpamConsole.log to print its logs as this function checks a configurable debug level before printing. Alternatively, the library could use the logs library which would give applications finer control over how and which log messages are displayed.
