Unfortunately, they are pretty broken, so I added them into floatmath.c

node: like in BeOS, it *must* own the root node (ie. via publish_vnode()),
unlike in BeOS, it must also drop that reference on unmount (symmetrical
behaviour definitely makes more sense to me than the Be way).
Since all existing file systems for Haiku behaved differently, I brought them
in line (only pipefs already adhered to that new standard for some reason,
rootfs did only released the node, devfs did nothing - despite it's probably
not really useful to be able to unmount them).
fs_mount() will now panic if a file system does not do this correctly (useful
for file system developing).
Unmounting is now theoretically working again: when trying to unmount a BFS
volume, the kernel crashes in the block cache destruction... (but that's work
for tomorrow).

from OS.h, sorry for triggering a complete rebuild.
To avoid doing a syscall for find_thread(0), the assembly
version is now in libroot. For BeOS R5 compatibility,
_kfind_thread_ is retained. This will fix some compile
problems, and provides a cleaner OS.h for future Haiku
versions.

was incorrectly calculated, and could therefore cause all sorts of troubles with
writes over 4 kB.

only a read lock on the inode, or without a lock at all (in case of prefetching) - it
is now using the cache_ref's lock to make sure it's retrieved only once and doesn't
waste/corrupts any memory.
- since that fix made it mandatory to fix write_chunk_into_cache() to not call pages_io()
while holding the cache_ref's lock (was a to-do item before), I changed it to make
that possible.
- It now also supports write-through caches in theory - as there is no way yet to tell
a cache to work this way.
- Optimized for the not so uncommon case of writing the last part of a file that is not
a multiple of the page size - it won't call pages_io() anymore then, but zero the rest
of the page directly.
- vm_page_write_modified() is now calling write_page() without holding the cache_ref's
lock as well.
The updated write_chunk_to_cache() is not so well tested, though, but appears to work
so far.

available.
Broken escape sequences are now properly ignored (read one character too much before).
Since the current line buffer is part of the history, we now delete that buffer when
crossing the current line again while traversing the history (restoring the former
buffer would be the nicest way, but that would require another empty buffer and more
copying).
Cleanup.

movement - IOW, the history of kernel debugger calls is now working also from
the on-screen KDL.

in an error message without checking for a NULL pointer (which happens during
early boot, and even though it would be impossible to get there at that time,
it shouldn't be accidently copied to anywhere else this way).
Added a compile time option to monitor the last thread that successfully
acquired a semaphore (disabled, though, only enable it when needed).
