freebsd_network: Add missing case for MCLBYTES in m_get2.
The first case is really just a standard mbuf without a cluster.
MCLBYTES should be the second case. This matches what FreeBSD does.

freebsd_network: Fix destruction of ref-counted ext_bufs.
The check as to whether or not the buf should be freed was wrong,
leading to incorrect frees.
Fixes double-free KDLs under the idualwifi driver that occur
on boot extremely frequently.

This returns an ext_buf that can be attached to an mbuf later,

freebsd11_network -> freebsd_network.
FreeBSD 12 has no major changes to the ifnet KPIs that constitute a
source compatibility break, save a single one related to locking
which doesn't really apply to us, and so we don't need to create
a "freebsd12_network" directory to work through the upgrades.

Replaced CACHE_DONT_SLEEP by two new flags CACHE_DONT_WAIT_FOR_MEMORY and
CACHE_DONT_LOCK_KERNEL_SPACE. If the former is given, the slab memory manager
does not wait when reserving memory or pages. The latter prevents area
operations. The new flags add a bit of flexibility. E.g. when allocating page
mapping objects for userland areas CACHE_DONT_WAIT_FOR_MEMORY is sufficient,
i.e. the allocation will succeed as long as pages are available.

slab allocator:
* Implemented a more elaborated raw memory allocation backend (MemoryManager).
We allocate 8 MB areas whose pages we allocate and map when needed. An area is
divided into equally-sized chunks which form the basic units of allocation. We
have areas with three possible chunk sizes (small, medium, large), which is
basically what the ObjectCache implementations were using anyway.
* Added "uint32 flags" parameter to several of the slab allocator's object
cache and object depot functions. E.g. object_depot_store() potentially wants
to allocate memory for a magazine. But also in pure freeing functions it
might eventually become useful to have those flags, since they could end up
deleting an area, which might not be allowable in all situations. We should
introduce specific flags to indicate that.
* Reworked the block allocator. Since the MemoryManager allocates block-aligned
areas, maintains a hash table for lookup, and maps chunks to object caches,
we can quickly find out which object cache a to be freed allocation belongs
to and thus don't need the boundary tags anymore.
* Reworked the slab boot strap process. We allocate from the initial area only
when really necessary, i.e. when the object cache for the respective
allocation size has not been created yet. A single page is thus sufficient.
other:
* vm_allocate_early(): Added boolean "blockAlign" parameter. If true, the
semantics is the same as for B_ANY_KERNEL_BLOCK_ADDRESS.
* Use an object cache for page mappings. This significantly reduces the
contention on the heap bin locks.

* Removed code duplication by merging destruct_pkt_mbuf and mb_free_ext.
This gets rid of one layer of indirection, too.
Also, this removed a potential memory leakage, when deleting external memory
in destruct_pkt_mbuf. In the case where memory of type EXT_JUMBO9 was
previously allocated, this would have been wrongly catched by the condition
(ext_type & EXT_CLUSTER) != 0.
* Renamed some variables to more human readable style.
* Commented some constants in mbuf.h to make more clear what they indicate and
to show that they should not be treatet as flags, as it was the case one
some locations before.
* Removed the EXT_PACKET constant, as it requests the same cache as
EXT_CLUSTER. EXT_PACKET is a optimizing technique from BSD, where a cache
exists holding some preallocated mbuf + cluster memory. Such a thing is not
implemented in the compat layer, at all. Though EXT_CLUSTER tells more
clearly what the size of the external data buffer is.

Also call construct_mbuf() from m_getjcl() as it initializes the mbuf fields. It
also handles the M_PKTHDR flag. Before, the uninitialized fields could be left over
from earlier freed mbufs and on m_freem previous m_next fields could be returned
resulting in random mbufs being freed. This makes the iprowifi4965 work and fixes
#5089.
