Bug fix: Free all memory and give better messages when memory is full.
* plugin-runner.c (add_to_char_array): Bug fix: If realloc fails, do not change old array pointer. (add_environment): Bug fix: If realloc fails, do not change old environment pointer. Also rename "e" to "envdef" for clarity. (main): Bug fix: If realloc fails, do not change old pointers. Also wrap "#pragma GCC" with "#ifdef ___GNUC___". * plugins.d/mandos-client.c (incbuffer): Bug fix: if realloc fails, free old buffer. (run_network_hooks): Moved variables "directory" and "ret" to their innermost possible scope. (take_down_interface): Moved variables "sd", "ret_errno", and "ret_setflags" to their innermost possible scope. (main): Removed variable "interfaces_hooks_size". Also, if argz_add fails when adding all found interfaces, the error message will now be correct. Also print error message if, after having taken up an interface, argz_add fails to add interface to list of interfaces to be taken down. * plugins.d/mandos-client.xml (OPTIONS): Explain better what "none" means as argument to "--interface" by negating sense. * plugins.d/password-prompt.c (fprintf_plus): Removed (unused).
