ncurses: only keep the version with widechar support
Only keep the widechar version of ncurses as libncursesw.so.9
Keep the old name to avoid breaking the ABI compatibility (the non
widechar version libncurses.so.9 is not binary compatible with
libncursesw.so.9) since all ports and base are already only linking
against the widechar version we can simply remove libncurses.so.9
Since the .9 version only lived in the dev branch and never ended in a
release, it is simply removed and not added to any binary compat
package.
Add symlinks to keep build time compatibility for anyone linking against
-lncurses
In libcasper, the first argument to the function is a structure that
represents a connection to Casper. On systems without Casper, macros
are used to interpose the Casper functions to standard libc ones.
This may cause errors/warnings that the variable is not used.
With the inline function, there is no such problem.

uma: Avoid unmapping direct-mapped slabs
startup_alloc() uses pmap_map() to map slabs used for bootstrapping the
VM. pmap_map() may ignore the hint address and simply return a range
from the direct map. In this case we must not unmap the range in
startup_free().
UMA uses bootstart and bootmem to track the range of KVA into which
slabs are mapped if the direct map is not used. Unmap a startup slab
only if it was mapped into that range.

The fsck_ffs program had previously only been able to expand the size
of its lost+found directory by allocating direct block pointers. The
effect was that it was limited to about 19,000 files. One of Peter Holm's
tests produced a filesystem with about 23,000 lost files which meant
that fsck_ffs was unable to recover it. This update allows lost+found
to be expanded into a single indirect block which allows it to store
up to about 6,573,000 lost files.
