logging: Add basic userspace support This commit adds basic userspace support to the logging subsystem. With this change, the following API could be called from user mode: - LOG_() - LOG_INST_(), - LOG_HEXDUMP_(), - LOG_HEXDUMP_INST_(), - LOG_PANIC(), LOG_PROCESS(), - log_printk(), log_generic(), log_buffrered_cnt(), - log_filter_set(NULL, ...) With userspace disabled, the logger behavior and performance is not affected. With userspace enabled, the calls from kernel space have an additional overhead introduced by _is_user_context(). The logger behavior changes when it is called from the user context. All strings logged using LOG_() and LOG_INST_() API from userspace are rendered in place for security reasons and then placed in log_strdup() memory pool, which should be large enough to hold bursts of log messages.
