<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This introduces a new logger routine ast_log_safe. This routine should be used for all error messages in code that can be run as a result of ast_log. ast_log_safe does nothing if run recursively or from the logger thread. All error logging in astobj2.c, strings.c and utils.h have been switched to ast_log_safe. One ast_log from stringfields code in utils.c was also changed.
I've also added support for raw threadstorage. This provides direct access to the void* pointer in threadstorage. In ast_log_safe I use NULL to signify that this thread is not already running ast_log_safe, (void*)1 when it is already running. This was done since it's critical that ast_log_safe do nothing that could log during recursion checking.
This review shows the version 13 patch. Version 11 didn't have the backtrace check for MALLOC_FAILURE_MSG, and trunk uses 'ast_callid' instead of 'struct ast_callid *'. Patches for each version are on JIRA.
The idea to use threadstorage to protect certain error logging came from the patch posted by Timo Teräs.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Verified with 'nm -g main/astobj2.o' that ast_log_safe was being used.
Tested by further modifying Asterisk with added calls to ast_log_safe().
* In main() after fully booted.
* In ast_log_safe() after setting in_safe_log.
* From the logger thread.
Only the message after fully booted was shown in the logs, all others were ignored.</pre>
