Subject: [PATCH] Add logic to handle memory allocation failures.
More generically, this patch adds handling of fatal errors.
Memory allocation failures are currently the only type of
fatal error.
- New C API config_set_fatal_error_func() allowing caller
to provide a fatal error handler.
- A default handler will write a message to stderr and then
call abort().
- The C++ library installs an internal handler that throws
std::bad_alloc
- Route all malloc/calloc/realloc requests through new
wrapper functions libconfig_malloc(), libconfig_calloc(),
libconfig_realloc(), which call the above and then check
the return value. If it's NULL, they call the fatal error handler.
- Force the flex- and bison-generated code to call the libconfig
alloc functions instead of their default ones.

+Specifies the function @var{func} to call when a fatal error is encountered.
+If @var{func} is @code{NULL}, the default fatal error handler function will
+be reinstated.
+
+@tindex config_fatal_error_fn_t
+The type @i{config_fatal_error_fn_t} is a type alias
+for a function whose signature is:
+
+@deftypefun @w{void} func (@w{const char *@var{message}})
+
+The function receives an error message @var{message}. The function is
+not expected to return to the caller; if it does, the resulting
+behavior is undefined.
+
+@end deftypefun
+
+Fatal errors are unrecoverable, and the only reasonable course of
+action is to abort the calling process. The default fatal error
+handler function writes a message to standard error and then calls
+@code{abort()}. One potential alternate implementation would be to
+call @code{exit()} with an exit status that indicates to the parent
+process (such as a watchdog process) that the current process has
+encountered an unrecoverable condition and should be respawned.
+
+In the current implementation, the only condition that will produce a
+fatal error is a memory allocation failure---that is, a @code{NULL}
+return value from @code{malloc()}, @code{calloc()}, or
+@code{realloc()}.
