Clean up the implementation cleanup mechanism. Also remove ->issymmetric,
since it's easier to just do it in dst_api.c.
Move the memory allocation wrappers into openssl_link.c, since they're
openssl specific.
add dst_key_privatefrombuffer(), which coverts a public key into a private
key.
- dst_lib_init()/dst_lib_destroy() allow dst to use a predefined
mctx and free all resources on exit.
- dst_key_tofile() & dst_key/fromfile() take a directory parameter.
- dst_key_parsefile() removed, replaced by dst_key_fromnamedfile()
- more bug fixes and memory leak fixes
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.
*/
