Reduce STDERR logging to only WARNING and above.

Browse Source 
INFO logs are now only viewable in the log file, which is not written
by default. A new command line option --log-file can be used to control
where the log file is written.

INFO logs can be written to STDERR if --log-all-to-stderr is passed.

General:

Command line options:
--language-server
Run as a language server. This implements the language
server spec over STDIN and STDOUT.

--test-unit Run unit tests.
--test-index Run index tests.
--log-stdin-stdout-to-stderr
Print stdin and stdout messages to stderr. This is a aid for
developing new language clients, as it makes it easier to
figure out how the client is interacting with cquery.

--log-file <absoulte_path>
Emit diagnostic logging to the given path, which is taken
literally, ie, it will be relative to the current working
directory.
--log-all-to-stderr
Write all log messages to STDERR.
--clang-sanity-check
Run a simple index test. Verifies basic clang functionality.
Needs to be executed from the cquery root checkout directory.
--help Print this help information.
Configuration:
When opening up a directory, cquery will look for a compile_commands.json
file emitted by your preferred build system. If not present, cquery will
use a recursive directory listing instead. Command line flags can be
provided by adding a file named `.cquery` in the top-level directory. Each
line in that file is a separate argument.

There are also a number of configuration options available when
initializing the language server - your editor should have tooling to
describe those options. See |Config| in this source code for a detailed
list of all currently supported options.
