6425fed7e6 LinuxKPI: Additions to rcu list. 
- Add rcu list functions.
- Make rcu hlist's foreach macro use rcu calls instead of the non-rcu macro.
- Bump FreeBSD version so we have a checkpoint for the vboxvideo drm driver.

1ef5e651fd Make the linuxkpi's alloc_pages() consistently return wired pages. 
Previously it did this only on platforms without a direct map.  This
also more closely matches Linux's semantics.

Since some DRM v5.0 code assumes the old behaviour, use a
LINUXKPI_VERSION guard to preserve that until the out-of-tree module
is updated.

6a65ca35dd LinuxKPI: Finalize import of seq_file. 
seq_file.h and linux_seq_file.c was imported form ports earlier but
linux_seq_file.c was never compiled in with the module. With this
commit base seq_file will replace ports seq_file and it required a
few modifications to not break functionality and build.

442d12d89c Fix regression issue after r346645 in the LinuxKPI. 
The S/G list must be mapped AS-IS without any optimisations.
This also implies that sg_dma_len() must be equal to sg->length.
Many Linux drivers assume this and this fixes some DRM issues.

Put the BUS DMA map pointer into the scatter-gather list to
allow multiple mappings on the same physical memory address.

The FreeBSD version has been bumped to force recompilation of
external kernel modules.
