Mostly, several functions that take pointers as arguments, almost
always char * pointers, had those pointers qualified with "const".
Those that returned pointers to previously const-qualified arguments
had their return values qualified as const. Some structure members
were qualified as const to retain that attribute from the variables
from which they were assigned.
Several unused functions removed from dispatch_tcp_test.c (left over
from when it was copied from dispatch_test.c).
Minor other ISC style cleanups.
Cleanup of redundant/useless header file inclusion.
ISC style lint, primarily for function declarations and standalone
comments -- ie, those that appear on a line without any code, which
should be written as follows:
/*
* This is a comment.
*/
return an isc_logconfig_t. isc_log_cretechannel and isc_log_usechannel
now take an isc_logconfig_t instead of an isc_log_t; this is to address
reconfiguration in a multithreaded environment.
isc_logconfig_create, isc_logconfig_get, isc_logconfig_use and
isc_logconfig_destroy were added to work with the new isc_logconfig_t type.
isc_logregister_categories and dns_log_init are now both void rather than
returning isc_result_t.
