The const is actually misplaced. const plist_t evaluates to void *const
instead of const void *. const qualification of the former makes no
sense in function declarations.

calloc is faster for big allocations. It's also simpler.

This will prevent an assert if a NULL pointer is passed, and can make
writing some code easier and cleaner without the need for a NULL check.
For example, plist_copy(plist_dict_get_item(dict, "abc")) would give us
a copy of the dict's node if the dict has a value for the given key, or
NULL without any further checks.

In ctime64_r, the call to localtime64_r can fail. If we don't check for
this and then call asctime64_r, the results are garbage.

As mentioned in #142, plist_copy_node() was not correctly handling the hash
tables when cloning array or dict nodes; it incorrectly filled the hash table
with the original child node info, which effectively would lead to a
segmentation fault / UaF if the original array/dict would be freed followed
by an attempt to access an element in the new hash table.

... and const versions of three member functions, each returning const_iterator:
* Plist::Dictionary::Begin()
* PList::Dictionary::End()
* PList::Dictionary::Find()

Bug: when creating a new Dictionary object (for example through PList::Node::FromPlist(plist_t node) ), the dictionary_fill function is called from Dictionary() constructor in line 50. It seems that the intended way of calling dictionary_fill() is to pass the _map object by reference, however it is actually passed by value. Thus the changes to the map object made by dictionary_fill() are discarded when the function returns.
Fix: pass _map by reference to keep the changes

Also fixes #126 by skipping the strlen() in the assert() if for some reason NULL is returned as data

Similar to #PLIST_DICT, an iterator can now be used for #PLIST_ARRAY
nodes. Get an iterator with plist_array_new_iter() and use
plist_array_next_item() to iterate over the elements.

directly
As Xiao Deng pointed out in #131, plist_dict_next_item() was very inefficient.
For each iteration, node_nth_child() was called with the iterator value, which
would walk through the child node list on EVERY iteration. If the dictionary
is large this makes things very slow. More than that, after reaching the key
node the code was calling node_nth_child() AGAIN (with iterator value + 1) to
reach the value node, which would walk through the node list once more.
This commit changes the iterator to be a node_t pointer so that the iteration
is done on the node list directly.
