ramfs: Properly acquire/release references to the vnode in VMCache.

This is what AcquireStoreRef/ReleaseStoreRef are for. We don't use
VMVnodeCache here because that is a non-"temporary" cache that
writes its pages back to disk, while we need a store for the pages
that won't discard unmodified ones when memory is low.

Add a close() to the mmap_cut_tests, which triggers the case where
this is important (a file is unlinked, mmap'ed, and then the lone
FD referring to it is closed, triggering the file's deletion unless
the mmap also acquired a reference to the vnode.)

Fixes KDLs with Firefox test builds.

kernel/vm: Add "unmergeable" flag to VMCache.

ramfs needs to create caches that are both temporary and unmergeable,
so add another flag to make this state possible.

Otherwise, mmap'ed files from ramfs might wind up in VMCache
trying to merge the caches when the last one is closed, which
we don't want.

ramfs: Use VM_PRIORITY_USER not VM_PRIORITY_SYSTEM.

This way, allocation failures on ramfs have a chance of
not bringing down the whole system with them.

ramfs: Style fixes to DataContainer.

No functional change.

ram_disk & ramfs: Use BStackOrHeapArray for the vm_page* arrays.

ram_disk & ramfs: Unify the _GetPages/_PutPages code.

Solves a TODO. No functional change intended.

* While we will likely never drop %Ld support,
lets clean house and set a better example.

ramfs: Switch from an embedded to a separately allocated small buffer.

This saves 16 bytes in the class vs. the old size, but more importantly
allows us to avoid allocating VMCaches and wasting an entire page for
any attribute larger than 32 bytes; instead, attributes can be up to
1024 bytes before we allocate a full page for them.

Unfortunately small files cannot take advantage of this optimization
right now as the cache is always used for them. I added a TODO about
this.

It isn't yet adapted to the new VFS API, so the build is still somewhat
broken.

Mmh, apparently I have to check the copied directory itself in first.
