Luiz Capitulino f2b07f35d2 QDict: Introduce new iteration API
It's composed of functions qdict_first() and qdict_next(), plus
functions to access QDictEntry values.

This API was suggested by Markus Armbruster <armbru@redhat.com> and
it offers full control over the iteration process.

The usage is simple, the following example prints all keys in 'qdict'
(it's hopefully better than any English description):

   QDict *qdict;
   const QDictEntry *ent;

   [...]

   for (ent = qdict_first(qdict); ent; ent = qdict_next(qdict, ent)) {
        printf("%s ", qdict_entry_key(ent));
    }

Luiz Capitulino 0d078b2ade QDict: Introduce functions to retrieve QDictEntry values
Next commit will introduce a new QDict iteration API which
returns QDictEntry entries, but we don't want users to directly
access its members since QDictEntry should be private to QDict.

In the near future this kind of data type will be turned into a
forward reference.

Luiz Capitulino c8bc3cd72b QDict: Small terminology change
Let's call a 'hash' only what is returned by our hash function,
anything else is a 'bucket'.

This helps avoiding confusion with regard to how we traverse
our table.

Blue Swirl 43dc2a645e Replace assert(0) with abort() or cpu_abort()
When building with -DNDEBUG, assert(0) will not stop execution
so it must not be used for abnormal termination.

Use cpu_abort() when in CPU context, abort() otherwise.

Blue Swirl 72cf2d4f0e Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.

Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

Luiz Capitulino fb08dde098 Introduce QDict
QDict is a high-level dictionary data type that can be used to store a
collection of QObjects. A unique key is associated with only one
QObject.

The following functions are available:

- qdict_new()    Create a new QDict
- qdict_put()    Add a new 'key:object' pair
- qdict_get()    Get the QObject of a given key
- qdict_del()    Delete a 'key:object' pair
- qdict_size()   Return the size of the dictionary
- qdict_haskey() Check if a given 'key' exists

Some high-level helpers to operate on QStrings and QInts objects
are also provided.
