Subject: Add env-var to set initial log-levels

name of environment variable: DLT_INITIAL_LOG_LEVEL

Syntax:
   <apid1>:<ctid1>:<loglevel1>;<apid2>:<ctid2>:<loglevel2>;...
   apid: application id (up to 4 chars), if empty all applications will match
   ctid: context id (up to 4 chars), if empty all contexts will match
   loglevel: either -1..6 or a symbolic name (default, off, fatal, error,
                                              warning, info, debug, verbose)

Examples:
DLT_INITIAL_LOG_LEVEL=TEST:LOG:0
-> turn off logging for appid TEST and contextid LOG

DLT_INITIAL_LOG_LEVEL=:LOG:warn
-> for contexts with name "LOG" set log-level to warning (3)

DLT_INITIAL_LOG_LEVEL=::VERBOSE
-> set log-level of all contexts to VERBOSE

DLT_INITIAL_LOG_LEVEL=::VERBOSE;TEST:LOG:3
-> set log-level of all contexts to VERBOSE except TEST:LOG, set this to WARNING

dlt-example-user: add option -l to specify log-level to be used when sending messages
