#941 LOG: Log service configuration not backwards compatible

[elunlen]

Problem

Application and System/Notification stream (mailbox queue) limits can be configured in the log service configuration object:
logStreamSystemLowLimit SA_UINT32_T 0 (0x0)
logStreamSystemHighLimit SA_UINT32_T 0 (0x0)
logStreamAppLowLimit SA_UINT32_T 0 (0x0)
logStreamAppHighLimit SA_UINT32_T 0 (0x0)

Previously environment variables where used (defined in logd.conf file). If a configuration object exists environment variables possibly from an older configuration are ignored. This breaks backwards compatibility.

See also [#841] LOG: Wrong default logStreamAppHighLimit (1)

Solution

The above attributes shall be handled as follows:
- If value is 0 and a corresponding environment variable exists the value in the environment variable shall be used.
- If the value is not 0 environment variable is ignored
- Configuration of the attributes is always logged in the syslog
