Change subject: PJPROJECT logging: Made easier to get available logging levels.
......................................................................
PJPROJECT logging: Made easier to get available logging levels.
Use of the new logging is as simple as issuing the new CLI command or
setting the new pjproject.conf option.
Other options that can affect the logging are how you have the pjproject
log levels mapped to Asterisk log types in pjproject.conf and if you have
configured Asterisk to log the DEBUG type messages. Altering the
pjproject.conf level mapping shouldn't be necessary for most installations
as the default mapping is sensible. Configuring Asterisk to log the DEBUG
message type is standard practice for collecting debug information.
* Added CLI "pjproject set log level" command to dynamically adjust the
maximum pjproject log message level.
* Added CLI "pjproject show log level" command to see the currently set
maximum pjproject log message level.
* Added pjproject.conf startup section "log_level" option to set the
initial maximum pjproject log message level so all messages could be
captured from initialization.
* Set PJ_LOG_MAX_LEVEL to 6 to compile in all defined logging levels into
bundled pjproject. Pjproject will use the currently set run time log
level to determine if a log message is generated just like Asterisk
verbose and debug logging levels.
* In log_forwarder(), made always log enabled and mapped pjproject log
messages. DEBUG mapped log messages are no longer gated by the current
Asterisk debug logging level.
* Removed RAII_VAR() from res_pjproject.c:get_log_level().

--- Functionality changes from Asterisk 13.13.0 to Asterisk 13.13-cert1 ------
------------------------------------------------------------------------------
+res_pjproject
+------------------
+ * Added new CLI command "pjproject set log level". The new command allows
+ the maximum PJPROJECT log levels to be adjusted dynamically and
+ independently from the set debug logging level like many other similar
+ module debug logging commands.
+
+ * Added new companion CLI command "pjproject show log level" to allow the
+ user to see the current maximum pjproject logging level.
+
+ * Added new pjproject.conf startup section "log_level' option to set the
+ initial maximum PJPROJECT logging level.
+
res_pjsip_registrar
------------------
* The PJSIPShowRegistrationInboundContactStatuses AMI command has been added
