log: provide missing macros

2021-01-17T00:17:11+00:00

With commit d094a0734cee ("log: allow for message continuation") we have
defined a special log level and category for message continuation. Let's
have a macro for using these.

If logging is enabled log_cont() will create a continuation log output with
the same logging level and category as the previous message.

If logging is not enabled, log_cont() will print like printf().

Provide macros for logging levels LOG_EMERG, LOG_ALERT, LOG_CRIT.

cmd: log: Add commands to list categories and drivers

2020-10-30T14:56:10+00:00

This allows users to query which categories and drivers are available on
their system. This allows them to construct filter-add commands without
(e.g.) adjusting the log format to show categories and drivers.

log: Add filter flag to match greater than a log level

2020-10-30T14:55:26+00:00

This is the complement of the existing behavior to match only messages with
a log level less than a threshold. This is primarily useful in conjunction
with LOGFF_DENY.

log: Add filter flag to deny on match

2020-10-30T14:55:26+00:00

Without this flag, log filters can only explicitly accept messages.
Allowing denial makes it easier to filter certain subsystems. Unlike
allow-ing filters, deny-ing filters are added to the beginning of the
filter list. This should do the Right Thing most of the time, but it's
less-universal than allowing filters to be inserted anywhere. If this
becomes a problem, then perhaps log_filter_add* should take a filter number
to insert before/after.
