pjsip/config_auth.c: Add missing whitespace to log messages.

The errors generated when validating 'auth' settings are missing a space which
makes the messages a little confusing.

config: bug: fix truncation of included config files on permissions error

ast_config_text_file_save() currently truncates include files as they
are processed.  If a subsequent include file or the main config file has
a permissions error that prevents writing, earlier include files are left
truncated resulting in a frantic search for backups.

This patch causes ast_config_text_file_save to check for write access
on all files before it truncates any of them.

Will be applied 1.8 > trunk.
