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.
required good entropy only when 'param' (to dst_key_generate) was non-zero.
Since the default was always to require good entropy, that default behavior
has been restored and now a non-zero param means that pseudorandom is ok.
- 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
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.
The macro DE_CONST is used to deal with a handful of very special
places where something is qualified as const but really needs to have
its const qualifier removed.
rdata.c now defines macros for the prototypes of the basic rdata functions,
and all of the lib/dns/rdata/**/*.c files now use them.
Some minor integer-compatibility issues. (IE, ~0x03 is a signed int,
so assigning it to an unsigned int should use a cast. The type of an
enum member is int, so there are some conversion issues there, too.)
A pointers-to-function should not be cast to a pointer-to-object.
Variables should not be named for C reserved identifiers.
One or two set-but-not-used variables removed.
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.
*/
